Cheap sun shades are the biggest risk for macular degeneration. Instead of protecting your eyes from intense sunlight, they harm your eyes more, than doing good.
1 How Your Eyes React To Sunlight?
Before wondering how expensive or inexpensive shades really matter as long as the lenses are dark, you need to know what happens to your eyes in the sunlight. In bright sun, your pupils constrict as a natural bodily response to the stimulation of sun’s intense bright light. When you wear cheap shades, your pupils dilate instead, thinking there is no danger and that’s when danger strikes because cheap sunshades then allow ultraviolet rays to filter through and that could seriously damage your eyes. You would be much better off not wearing sunshades at all.
According to Joann Kang, M.D., Asst Professor, Ophthalmology and Visual Sciences at Einstein College of Medicine, New York City, if UV light is allowed to fall on the surface of the eyes, it can lead to abnormal growths called pinguecula and Pterygia. In addition to such a condition, the harmful effects of sunlight on eyes can also lead to cataract and various forms of macular degeneration or even eye cancer.
2 Good Sunglasses Have a UV Factor for Total Protection
When it comes to wearing sunglasses, there shouldn’t be any compromise as cheap sunglasses damage eyes. The safest pair of sunglasses would be those which feature a hundred percent factor of both UVA and UVB protection.
A good pair of sun shades will always carry a label, depicting its UV absorption factor measured in NM which is the wavelength of UV rays. Thus, sunglasses would have this tag mentioned- “UV absorption up to 400NM”, this would then mean that you are fully protected against UV radiation. You may also find the label mentioning the fact that the sunshade has a light blocking factor of 75 to 90%. This means you are thoroughly protected.
3 Good Sunglasses Should be Comfortable on Your Nose
Even if you wear contact lenses, which feature UV protection, it won’t be adequate and you would still need a good pair of sunglasses. If this sounds alarming to you that you may have to spend a lot on sunglasses, then you need not. There are many ophthalmologists and spectacles shops which sell trendy and fashionable sunglasses having the prescribed UV protection within reasonable rates. Of course, if you want that fancy designer Ray Ban, then most probably it would cost a tidy sum, but the main issue of sunglasses is its UV protective feature and its size, which should fit you in a comfortable manner without slipping down the bridge of your nose.
According to Kang, the best kind of Sunglasses which feature a total prevention of sunlight is the wraparound sunglasses. Now that you know that cheap sunglasses damage eyes, avoid them at all costs as prevention is so much better than cure.
