Laylas Black Sun Readers offer a stunning translucent frame in a black shade. Also grey graduated lenses and spring hinges for comfort and durability. Filter Category 3 provides extra protection from both visible and UV light. These lenses will usually only allow less than 20% of visible light to penetrate the lens. This means that they will block out 80%+ of light.
Are the more expensive sunglasses of better quality?Not necessarily. While expensive sunglasses usually are high quality, you can also get a good pair for under £20 if you’re a careful shopper. Just make sure to check that the lenses provide adequate protection from UV light and are free of distortions.
Gradient lenses are tinted from the top down, so that the top of the lens is darkest. These lenses are good for reading, because they shield your eyes from overhead sunlight and allow more light through the bottom half of the lens so you can see your book clearly.
What are my options to prevent UV damage to my eyes?
You must wear sunglasses to prevent damage to your eyes. While some contact lenses provide UV protection, they don’t cover your whole eye, so you still need sunglasses.
Look for sunglasses that protect you from 99 to 100 percent of UV light.
When do UV rays affect my eyes?
Most people think that they’re at risk only when they’re outside on a sunny day, but UV light can go right through clouds, so it doesn’t matter if the sky is overcast. The sun’s rays are strongest between 10 am and 2 pm.
Glare and reflections can give you trouble, so have your sunglasses ready if you’ll be around snow, water or sand, or if you’ll be driving (windshields are a big glare source).
The following put you at additional risk: sunlamps, tanning beds and parlors, photo sensitizing drugs and living at high altitudes or near the equator.
