A Guide to Frequently Asked Questions About Sunglasses, Part 1 of 2

Olympic Eyewear addresses several common issues related to eye health concerns.

  • Even if the sun is not bothering someone’s eyes, it’s still important to regularly wear sunglasses that protect against UV rays. Exposure to harmful UV rays can result in pingueculae, photokeratitis and even permanent retinal damage.
  • UV rays contain three different types – UVA, UVB and UVC. UVA rays generally have a longer wavelength, which allows them to easily pass through glass. It is debatable whether this type of UVA ray causes intense eye damage. UVB rays are extremely dangerous and harmful, but appropriate sunglasses protection can prevent penetration directly into the eyes. UVC rays are so high in the atmosphere that they are blocked and do not reach the earth.
  • UV rays can penetrate directly through clouds and dim light. Even if the sky is overcast, the brightest sunrays are between 10AM and 2PM. To help avoid glare, people should make a habit of wearing designer wholesale sunglasses near water, snow, sand or while driving. Additional sources of damaging UV exposure include tanning beds, sunlamps, high altitudes, areas near the equator and even photosensitizing drugs.
  • Some medical problems can even exacerbate UV damage, especially people that have experienced cataract surgery, retinal dystrophies and macular degeneration.
  • To help prevent eye damage, sunglasses are needed. Some contacts offer minor UV protection, but since they don’t cover the entire eye, it’s important to still wear sunglasses. Sunglasses that offer 99% to 100% of UVA and UVB light protection are the best options. Sunglasses that are UV 400 help block light. Wraparound X-Loop sunglasses can help eliminate harmful UV rays from penetrating the corners of the eyes.
  • There are several different types of lens coatings that can help reduce glare and improve vision. Blue-blockers help reduce blue light, which is extremely harmful to the eyes and may lead to macular degeneration. Designed to heighten contrast, these are popular among boaters, hunters, skiers and pilots. Other popular lenses types include polarized lenses, anti-reflective coatings, mirror-coated lenses, gradient lenses, double gradient lenses and photochromic lenses.
  • Impact resistant lenses are required by the Federal Drug Administration and are especially helpful when playing sports, as they offer substantial safety from damaging and harmful impacts.
  • The degree of darkness has nothing to do with UV protection and some lighter tints can even offer higher levels of UV protection. Just because some sunglasses are expensive, doesn’t mean they offer superior protection against the elements or harmful UV rays.
  • Performance wholesale sunglasses are popular among athletes, Olympians and sports enthusiasts. These performance-enhancing lenses can actually increase and enhance vision, which is especially popular among snow sports and golf activities.
