As an adult you can chose when you wear your glasses within reason. If you cannot see to read the driving standard line without glasses then you must wear your glasses to drive. The same goes for any jobs that require a certain vision standard. However, in your own time, it's entirely up to you if you want to see the world in focus or not. I'll give some examples below.
The low to moderate myope (shortsighted person)
You are a low to moderate amount of short sightedness (myopia). For example your glasses prescription has a "-" not a "+" and says between -0.25 to -1.50ish.
In this case your close up vision, if you are under 40, will be perfect. Your distance vision will be blurred to some degree. To most people, having a blur in the distance is acceptable. Glasses make things clearer but unless they are specifically watching tv, going to the cinema playing golf or driving, they don't mind not being able to see far away. Also for short-sighted people, focusing close up is less effort for their eyes without their glasses on.
Some low myopes prefer to have perfect vision all the time so will keep their glasses on all the time. There is no such thing as wearing your glasses too much and making your eyes worse. Think about it, you are correcting your vision back to zero, as if you had no prescription. Would you tell someone with perfect eye sight to get some glasses to blur their eyes so that they don't make their vision worse by having it perfect all the time?? Of course you wouldn't, that would be ridiculous! So when people ask if they should "give their eyes a break" from their glasses, the answer is no!
The opposite should also be considered, will wearing my glasses all the time make my eyes worse? Absolutely not! By correcting your prescription and giving your brain a clear image this will not lead to an increase or decrease in your prescription. If it was going to change it would have changed regardless of whether or not you wore your glasses (I'm only talking about adults here). People think that wearing glasses full time will make their eyes reliant on them. The fact is, your brain will prefer the clearer vision and once you've been wearing your glasses all day, when you take them off you'll realise how blurred it was before you put them on by comparison! If you want to go back to not wearing your glasses then give it a few days without them and your brain will be used to living in a blur like it did before you started wearing glasses.
The moderate to high myope
The next patient is the moderate to high myope. Your glasses prescription is around -3.00 to -6.00. Now most of these people will wear there glasses all the time because anything past 20-33 cm is out of focus.
When these patients reach their early 40s they realise they can focus better without their glasses on so they lift them up or remove them to read. As long as their eyes remain healthy, they will always be able to see close up without with glasses because this is naturally where their vision is focused, with no effort from their eye muscles.
When it gets to the point where they have to lift up their glasses to see anything that is close up, approximately age 50-60, they find the glasses are on and off all day long. This is the point they usually switch to a bifocal or varifocal. Even then, when reading a book these patients will often take their glasses off and use their natural focal point again.
The low hyperope (longsighted person)
Next is the low hyperope. This time the glasses prescription has a "+" not a "-" on front of the numbers. Eg +1.00 to +3.00ish. As a young person you can use the muscles that change the shape of your lens (inside your eye) to focus long sightedness and see fine.
Long sight means the eye is too short or the lens inside the eye is too weak. By using the eye muscles either side of the lens to increase the power of the lens, we can bring the focal point that was behind the retina, to be focused clearly onto the retina.
When we are young we can do this all day long with no problems. As we age however, the lens inside the eye gets thicker and the muscles find it more difficult to pull it into shape to focus over any long sight. This can lead to eyestrain and headaches. At this point the low hyperope will usually start to wear glasses, not necessarily to improve the vision but to relax the eye muscles and relieve eyestrain, hopefully prevent the headaches they may have been getting.
Whatever your prescription, when we focus for close up, we do the same, use the muscles in our eyes to increase the strength on the lens to bring near objects into focus. So someone who is longsighted and doing a lot of close work, may find they need to use their glasses to relive some of this strain as their eyes will be trying to focus over the long sight and then extra focusing for close up objects too.
The astigmat. Is that a real word? Who knows! I'm talking about patients with astigmatism. Now you can be long-sighted or short-sighted with astigmatism.
It basically means your lens in your eye or cornea at the front of your eye (or both) are more curved in one direction than the other. This is sometimes referred to as "rugby ball shaped eyes". Now that is a massive exaggeration as your astigmatism would be off the charts if the 2 curvatures were that different but plenty of opticians use this analogy. Also it is only talking about the shape of your cornea and lens, not the whole eye.
Basically having astigmatism means you have 2 focal points in your eye. If you have some long-sight with this then your eye muscles can pull the 2 focal points as close to the retina as possible. If you are short-sighted with astigmatism then your glasses will do this for you. If there is only a small amount of astigmatism -0.25 or -0.50 then you might not need this corrected, especially if it is fairly straight (near to 90 axis or 180 axis on your prescription). If your astigmatism is higher than this or if it is at an oblique angle like 130 or 50 then you're more likely to want to wear glasses to improve the vision.
If you are wearing glasses then any astigmatism will be corrected. We would only leave it uncorrected if you didn't want glasses at all. Astigmatism can also lead to eyestrain and headaches if uncorrected although this varies from person to person.
If you are interested, always ask your optician if you aren't sure whether you are long-sighted or short-sighted and if you have astigmatism. Don't be afraid to ask questions about how often to wear your glasses if you're not sure. Hopefully this blog will help you make up your own mind. I must reiterate, this advise is only for adults. See my last blog about the plastic brain for more info about children's vision. Do not tell a child not to wear their glasses unless you have been specifically told by their own optician/orthoptist/ophthalmologist, especially if the child is under 8 years old.
As always, any questions for me, comment below.
My screw has come loose, what do I do?!
You've had your eye test, you get your new glasses, 2 months later one of the screws has worked loose and come out and the side has fallen off the glasses! That's ok, you pop back to your opticians and they mend it for you. Easy right? But what if you had your eye test at home because you couldn't get to the opticians? Should you call them to come all the way back to see you just to put in a new screw? YES! Definitely yes you should. If the side has fallen off your glasses, either they're un-wearable or very wonky! Making sure you can see as well as possible and as comfortably as possible goes beyond the hour we spend with you for your eye test. If your new glasses come loose and start slipping down your nose, call us and we will come and adjust them for you, no charge. Any problem with your sight or your glasses, we will do our best to help you.
My vision is getting worse but I'm not due another eye test for 6 months, what should I do?
Call your optician and book in another check. This goes for high street opticians as well as home visiting opticians. If your optician has recommended a 1 year check, that is assuming everything is normal. If you notice a change even 1 day after your check, you should book another one in. Sometimes it's just a case of adjusting your glasses, but sometimes it can be a problem with your eye health that needs seeing to urgently.
I'm getting headaches and I never used to get them, who should I talk to?
In this situation, as well as contacting your GP, it is a good idea to also book a check with your optician. There are some headaches which can be caused by your eyes and other more serious headaches that can be detected by checking thr back of your eyes. If there is anything causing swelling on the brain, it will often also cause swelling at your optic nerve which can be detected by looking at the back of your eye with an ophthalmoscope. Your optician can then refer you as urgently as necessary. If you have an eye test and everything is normal then you can tell your GP which will help them rule out some causes of headaches.
I had an eye test and didn't want new glasses at the time but now I fancy a new pair.
If your eye test is in date then you don't need another one. You can use the prescription issued to buy glasses wherever you want. If you had a home visit then book in for a home dispensing appointment to choose new frames. If your eye test was done elsewhere we will happily do a quick check to make sure the prescription is perfect before making your new glasses.
I can't see the tv well enough with glasses, can't you make them a bit stronger?
This is a common misconception for distance vision/tv glasses. Your glasses only correct your long or short sightedness. "Making them stronger" will only move the focal distance closer to you which will in fact blur the distance/tv. However, this can work for reading glasses, the stronger the reading prescription, the larger things seem because they are magnified, but also the closer the focal distance will be. So increasing the magnification of reading glasses can be done to a certain extent but be prepared to hold your book much closer to your face. For some people this works quite well. If you are struggling with very small print then an extra dioptre on your reading glasses could make this manageable. However, if you have significant sight loss then this may not be enough even to read large print. This is where hand held magnifying glasses come in. These can be obtained through the NHS at a hospital low vision clinic or privately though your optician. We carry a range of magnifying glasses which you may try for free then if they help then you can either purchase one or be referred for free ones.

Don't worry, this isn't another lecture about single use plastics and how we shouldn't be using and throwing away plastic straws! It's actually about the plasticity or the brain, in particular, the visual system and how to ensure your child develops normal eyesight.
We don't actually see with our eyes, we see with our brain and for our brain to be able to see the world around us we need a good clear image from both eyes. This allows our brain to put together an accurate representation of the world.
Our visual system is developing up until around the age of 8. So for normal vision to develop, the eyes need to be providing this clear image.
"But my child can see fine!" Can they? How do you know? Children's books are in exceptionally large print, often larger than large print books for people who are partially sighted. Also how do you know both eyes can see? One eye might be seeing fine but if the other cannot then it's difficult if not impossible to obtain normal 3D vision. So what do I need to do? I'll tell you.
1. Get an eye test for your child. Opticians can check your child's prescription at any age but if there is no family history of eye problems then age 3-4 is a good age for their first test. Children are more cooperative by this age and there is plenty of time to prescribe glasses if needed.
If there is a family history of long sightedness, a turn in the eye or lazy eye then come around age 1-2. If you notice a turn or a white reflex in your child's eye, come straight away, any age.
2. Do not allow your child under 8 to have any hair style that covers or partially covers one or both eyes. This will likely lead to the eye becoming lazy (not seeing as well). Even if your 7 year old has perfect eyesight, if you let them have a side fringe that even partially covers one eye, the brain will stop receiving a clear image and even though the eye is healthy, the brain won't see properly through this eye. By all means, if your 10 year old wants their hair across their eyes, go ahead. Your 12 year old wants to be a pirate? Visually speaking, no problem! You can patch an adults eye for a year, take off the patch and their vision will be the exact same. Do that to a 6 year old and they may not be able to read anything on the letter chart when you take off that patch.
3. iPad time. If your child is shortsighted then you should limit any unnecessary close work as evidence suggests it will make your child more shortsighted. There is no evidence to suggest that close tasks will make you more shortsighted if you aren't already. So if you're longsighted then using a tablet or iPad shouldn't make you more shortsighted. Evidence is not clear about long term damage to your eyes due to screens but as a precaution you could get a coating on your glasses to filter out the blue light.
I'll do a separate blog which details the problems children can have with their eyes but if in doubt, see an optician. Children get free eye tests up til the age of 18 if they are still in full time education. If you child has autism or any other health problems that make if difficult for them to get to an optician or to cope at an opticians then we can see them at home for free. We allow 1 hour for every appointment so if your child needs a break during the test that fine.

In this blog I'll discuss all the reasons someone should have glasses and the occasions when someone may be better without them.
One of the most common phrases I hear from relatives is, "my mum has dementia and she doesn't read so she won't need any reading glasses". There are two situations here. The patient isn't reading because they can't comprehend it due to their dementia or they aren't reading because they haven't got any glasses to read with and it's been assumed that's it's due to dementia. Either way, "reading glasses" is really just a term for glasses that help with ANY near task. Looking at family photos, reading birthday cards, card games, board games, and seeing their food to name a few. It can be difficult to get elderly people to eat enough food at the best of times. Maybe allowing them to see what their eating by wearing a pair of glasses may just help a little. Even if it doesn't, wouldn't you like to be able to see what you are eating or what someone is feeding you if you're not able to do it yourself?
It's a similar situation for distance glasses or "driving/tv glasses". Some opticians will name them after the tasks which most people use them for but in actual fact they are just glasses to help the person see everything in general life that is past about a meter. Seeing the faces of family members, the carers, doctors, nurses, anyone who comes to see them.
Often people with dementia can lash out of or become aggressive. One of these reasons could be that they don't recognise who is approaching them because they are blurry. So even if the patient doesn't drive or isn't interested in the television, it doesn't mean they should be living their whole life in a blur. If patients are able to walk and could be at risk of falls, this is another reason to correct their vision with glasses.
I had a patient once who was very short-sighted and her daughter was worried that she was forgetting who she was as she never recognised her when she came to visit. The actual reason was because she couldn't see past 10cm clearly. Her daughter walking in was just a blob of colours. Once she got her new glasses, it was no longer a problem and she wore them all the time.
When are glasses inappropriate?
There are a few situations when glasses won't help or may even be a danger to patient.
1. The patient had dense cataracts or end stage glaucoma or end stage macular degeneration (or any other eye condition that renders the patient unable to see). In these cases glasses will be of no benefit. However, in patients with dementia sometimes they think they can see ok and maybe they've worn glasses all their life. If a patient becomes distressed when their glasses are removed then let them keep them on, even if they aren't benefiting their sight. If their glasses break and they want to replace them, the easiest thing to do it to buy some cheap ready readers as they are just for the feeling of having glasses rather than the sight.
2. The patient doesn't need glasses for distance and doesn't settle down very often, i.e they constantly walk around and often get up even if someone asks them to sit down. In this case I wouldn't prescribe reading glasses in case the patient gets up and starts wandering when wearing them and is then risking falling due to their distance vision being blurred through the reading glasses. I would only prescribe reading glasses if there is someone who can stay with the person while eating or looking at photos and immediately take them off of they start to get up and wander off. The glasses shouldn't be left anywhere where the patient can help themselves and put them on.
3. The patient has one eye that is clear for distance and one that is clear for close. This is done artificially in some cataract patients. One cataract is removed and the eye is corrected for distance vision then when the second cataract is done, it is left clear for close to. Some people have this naturally in which case they have no need for glasses.
4. The patient constantly have their eyes closed.
5. Wearing glasses distresses the patient and they will just throw them off. In this case we should still reassess each year as their a attitude towards glasses will likely change as their dementia changes.
6. Very advanced dementia where a patient has no visual demands at all (not even looking at people who come in so showing any interest or response to photos etc)
Bifocals or varifocals?
I prescribe bifocals or varifocals for the majority of dementia patients who are none mobile. Having a bifocal means they have one pair of glasses which can be kept on to see general vision as well as close up without having to swap between taking glasses on and off or between 2 different pairs. Often the patient won't be cognitively able to take them on and off and put on a correct pair of glasses for a specific task, and also may not realise if they are sat watching tv in their reading glasses. Bifocal or varifocal glasses for patients who are none mobile won't increase risk of falls. I would only prescribe them for patients who walk if they are very stable or have always worn this type of glasses and haven't been falling in them.
A situation when mutifocal glasses are inappropriate is when a patient is bedbound and spends the majority of time lying flat in bed. If their tv is high up on the wall this might be ok. If it is level with the bed then the patient may be watching it at an angle where mutifocal glasses won't be appropriate. If the reading area is in the way then a single vision distance pair is more appropriate for watching tv and separate close glasses for near tasks. This doesn't mean they can't have a bifocal for when they are sat up on bed if they want one.
Dementia eye test
Levels of dementia vary greatly between patients even if they have the same type of dementia. Some can read the chart and carry out a normal eye test whereas some can't tell me what the can or can't see. We have specialist training and equipment that allows us to measure a patient prescription for glasses and that allows us to see the back of the eye to detect any eye problem that may reduce sight. This allows us to know whether glasses would actually benefit the wearer or whether their eyes are too damaged to benefit from glasses correction. I'll do a separate blog post all about the dementia eye test so keep an eye out if you'd like more information.
The simple answer is yes! If you need one then you can! For most people this is a free service funded by the NHS. So many people are unaware that this service exists but it definitely does! If you are entitled to a free eye test at an opticians but you are unable to get out on your own due to physical or mental health constraints, you will be entitled to a free eye test at home too. This includes (but is not limited to) people over 60, people with diabetes and people with glaucoma in their immediate family. There is a link to the full list of who is entitled to a free eye test here.
If you are not entitled to a free eye test then you can still have one at home. Our private fee at Freedom Eyecare Nottingham is £45 and that includes the eye test, glasses fitting and a full aftercare service including any adjustments. This is reduced to £25 if you buy glasses from us. We also provide low vision assessments free for anyone who still struggles to see, even with glasses on, perhaps due to cataracts or macular degeneration.
If you are in hospital, unfortunately the NHS will not fund your eye test until you are home. However, we can provide a discounted private eye test at £25 should you wish to have one done whilst still in hospital. If you lose or break your glasses in hospital and your eye test is in date, we can come out for free to help you to choose some new glasses.
Below are some of reasons people may require a home eye test:
If you're unable to get to an opticians unaccompanied for any reason, then we can come to you.
Here at Freedom Eyecare Nottingham, home eye tests is all we do. If you want to book an eye test for someone but they are not able to communicate, we are still able to test their eyes. Many people with autism, advanced dementia or have suffered a stroke are unable to tell us what they can see or answer any questions about which lenses are better or worse. We have specialist training and equipment that allows us to measure someone's eyes for glasses and to see into their eyes so we know how well they will or won't be be able to see with glasses, even if they can't communicate. When an optician looks into your eyes with an ophthalmoscope, they are not only able to check the health of the eyes but can also detect and monitor other health problems such as diabetes, high blood pressure and even increased pressure in the brain.
For relatives of people with advanced dementia or autism there can be a worry about unpredictable or challenging behaviour. If an eye test is booked but cannot be finished for any reason, we can come back another day. We are experienced in testing people with these conditions and always allow plenty of time for each patient, up to an hour if necessary so there is no rushing around and we can try and make the eye test as easy as possible for each patient.
At Freedom Eyecare Nottingham, we are an independent optician and specialise in home visits. Our patients can benefit with very competitive cost of glasses starting from as little as £49 which includes glasses frames and hard coated lenses. We have a whole range of glasses which we subsidise for patients who are entitled to an NHS voucher so that there is nothing to pay for this range. We also have a range of tough, flexible frames and plenty of other glasses to browse through that patients can put an NHS voucher towards. We can make tv glasses, reading glasses, computer glasses, bifocals, varifocals, sunglasses, glasses that change in the sun, anti glare, anti scratch, you name it and we will try our best to provide it.
If you need help or have any questions about home eye tests, please give us a call on 01157866320. We cover all of Nottinghamshire and can provide eye tests further afield if needed. There are only two of us in the team so if we are both out testing eyes, please leave a message and one of us will get back to you as soon as possible. If you'd rather email us you can contact Info@freedomeyecare.co.uk.

We have experienced one of the hottest summers in history and now as we enter October, the nights are drawing in and the temperature is getting cooler. It now won’t be long before we are having to put the heating on and brace ourselves in the cold and wintery conditions on our daily commute and everyday activities. Take a moment to think about the elderly who may live on their own and have limited mobility. A trip outside to the shops in the winter and snow may not seem too difficult for most of us, but anyone who has a physical disability or impaired mobility, such a task is very daunting and possibly dangerous.
With the NHS reporting an increase of admissions to A and E as a result of falls in the winter, it is understandable how many would be hesitant in going out to have their eyes tested. If a problem with their eyes or vision occurred suddenly, many would worry how they would get to someone to check their eyes. Some people may be fortunate to live near relatives or friends who are able to take them to the opticians, however some may not live near relatives or have anyone who are able to help them. I have spoken to a few patients who explain they feel almost like a burden and would rather not inconvenience anyone. Often many will suffer in silence, but as with any medical condition, the earlier things are detected, the better outcome it can be.
For friends and relatives who work full time they may struggle to get the time off to take their elderly relatives to various health care appointments especially if they have numerous conditions. Sometimes the physical difficulty, tiredness and subsequent stress may be too much for some for both the patient and their carer or relative.
Fortunately there is a solution! Did you know that you can have your eye test done in the comfort of your home if you have any condition that limits your ability to go to an optician unassisted? You can get an NHS eye test at home for free if you qualify for an NHS eye test. Below is a list of who is able to get an NHS eye test.
You qualify for a free NHS funded sight test if:
Ann Hamilton (left) and Stephanie Lipsey-Liu (right) Freedom Eyecare Nottingham's home visiting optometrists.
Stephanie and I created Freedom Eyecare Nottingham, a home visiting opticians service. We are based in Nottingham and we cover all of Nottinghamshire. Set up by myself and Stephanie, we are both optometrists who have worked in hospitals, high street and independent practices who love doing what we do. My late grandma was the reason why I wanted to provide domiciliary eye care. She was house bound in the last four years of her life, but she valued her vision greatly. Although she wasn’t able to get out, she still enjoyed the everyday activities such as watching TV, reading a book and bird watching. It also enabled her to maintain a sense of independence. That is the most important and rewarding part of our job, helping people see better to enjoy life.
The eye test is just like at the opticians (including the ‘puffy eye machine!’). We perform a full and comprehensive eye examination including the glaucoma check. We also bring glasses should you need to change them, our range vary from free NHS ones to designer glasses. We believe in quality and affordability and have a great range of glasses to choose from, we never pressure sell as we never take any money up front, unless you wish to leave deposit and allow a cooling off period should you change your mind. A summary of the order is given at the end of the eye test so the customer knows what they have ordered and that is often required if there is a power of attorney.
We do understand there can be times where the patient needs to be referred for treatment and we are able to refer just like a in-store optician for treatment such as cataracts and wet macular degeneration. For people who are sight-impaired we also provide free low vision assessments and have a wide range of magnifiers and adjustable lighting.
Essentially, we provide a complete eye care service at the comfort of your home. Not surprisingly, not many people are aware that such NHS services exist! If you know anyone who would benefit from having an eye test at the comfort of their own home, please visit www.freedomeyecare.co.uk or call 0115 7866320.
