5 Facts About Sunglasses
Higher cost does not mean better UV protection. The price of your sunglasses is not a reasonable indication of how well they block ultraviolet radiation. There are expensive designer sunglasses that do not provide the best UV protection and there are inexpensive sunglasses that adhere to high standards.
Children’s eyes are just as susceptible to sun overexposure and glare as adults eyes are. Children should also wear sunglasses to help protect their eyes from too much radiation.
Overexposure to the sun’s ultraviolet light can aggravate eye growths, cataracts, and macular degeneration. Scientists suspect that too much exposure to damaging ultraviolet light can cause common eye problems much later on in life. Wearing sunglasses that block UV light is one way of minimizing this potential risk.
Ultraviolet radiation is not visible light. UV rays are not visible to the human eye. They are invisible. So your eyes can still be exposed to ultraviolet radiation even on a cloudy day with low available sunlight.
Lens darkness does not indicate greater UV protection. Although darker tinted lens can provide more comfort in bright or harsh and glaring light, it is really the UV absorption ability of your lens that makes the difference in UV protection. However, lens of different colours can provide varying degrees of clearer visibility or contrast.
