SUNGLASSES
It is very important that you have the correct sun-glasses for light sensitivity.
Sunglasses can be used all year round and the correct sunglasses and correct level of tint or colour is most important. If you suffer from a particular eye condition, such as, age-related macular degeneration (AMD), glaucoma or cataracts, then this can increase your sensitivity to light.
Having no sunglasses or the incorrect tinted spectacles can cause discomfort and reduce your sight further. On some days you may find daylight particularly difficult.
As Opticians we have to find the balance for you between reducing sensitivity while still making sure that you still get enough light to make the most of your vision. We must also ensure that your sunglasses have your most up to date spectacle prescription to ensure that your vision is as good as it can be and also achieves the required level of vision for driving.
Regular sunglasses will cut the amount of light entering the eye, but if you do not have the correct prescription fitted in your sunglasses then they will also reduce your sight. Furthermore, they may not give the relief from glare symptoms that you require.
For some people cutting down on the light level entering the eye helps; for others, cutting out certain ranges of light colour helps more. The best combination varies from person to person and there is no current evidence to say which colour is best for particular eye conditions. It’s always best to try a wide range to see what works for you. As Vision Specialists we can show you the range to see which you find best.
Do not choose a pair of glasses based on an advert and style alone. Our advice is to choose a well fitted frame for style and fashion but take advise on the lenses that are fitted to these frames.
It’s best to discuss your symptoms with our vision specialists.You may find that different filters work better for you in different situations. Some patients prefer to have two different pairs; one with a dark tint for sunny days and one with a lighter tint for less bright days. Alternatively, some find photochromic lenses helpful. These lenses change with the light conditions.
A well-fitting frame should sit close to your face comfortably. Eye protection designed for people with sight loss offers more coverage than a standard pair of sunglasses, with top panels and wider arms to block light entering the eye.
As Opticians we will help you ensure you have the right fit.
All sunglasses sold in the UK should have ultra-violet (UV) filter as standard that will also protect your eyes from the harmful UV rays of the sun. These should have a CE mark (European Conformity) and some may have a UV400 mark.
However, take caution when buying abroad. Even in the UK it’s not always clear whether a pair of lenses is correct to the markings on their frame. To be safe, only buy from responsible stockists. It’s also important to be aware that darkness of a lenses’ tint has no bearing on how much protection from UV they give.
Although UV filters don’t help with glare, it's important to protect your eyes from the sun as there is evidence that high exposure to UVA and UVB are risk factors for the development of cataracts. The best lenses will have protection against both UVA and UVB light.
