If you like to hit the road during the daytime, always wear good quality sunglasses, says Dr Lee. Look for sunglasses that block 100 per cent of UV rays, and choose close-fitting wraparound styles that help to block light rays coming in from the sides. This is especially important if you spend many hours in the sun.
Even if your contact lenses block UV rays, you still need sunglasses. UV-blocking contacts shield only part of your eyes under the lens. UV rays can still damage the conjunctiva (white of the eye) and other tissues not covered by the contact lens. Wearing sunglasses protects these delicate tissues from UV damage. It is also a good idea to wear a cap when the sun is directly overhead to block off the UV light entering the eyes from the top.
