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. All of Olympic Eyewear's bulk sunglasses comply with US and International UV Protection Standards and the majority of them are made with polycarbonate lenses which have the natural ability to block more than 99% of the sun's UV light.
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. CG Sunglasses, X-Loop Sunglasses, and Biohazard Sunglasses have a variety of kids' sunglasses that reflect popular trends and that will be attractive to children.
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 colors can provide varying degrees of clearer visibility or contrast. Olympic Eyewear has a vast array of sunglasses in bulk that come in with diverse lens colors, from dark to light tints.
Higher altitudes are exposed to more UV rays. The higher up in altitude you go (if you live on a mountain for example), the thinner the earth's atmosphere, and the less effective the ozone layer at blocking radiation. It stands to reason then that people who live at higher altitudes should be a bit more concerned about UV protection.
Gazing at the sun even with sunglasses on is still a bad idea. Although your lenses may protect your eyes from UV radiation, gazing directly at the sun can still damage your retina.
Getting enough daily exposure to the sun is important for your health, but make sure you take the necessary precautions. When you plan to be out long or participate in recreational activities outdoors, remember to grab your sunglasses!
