POLARIZED SUNGLASSES VS UV... WHAT'S THE DIFFERENCE?
Learn why polarized uV400 sunglasses are a must here in trinidad and tobago from blue lightning
First, What is UV?
Ultraviolet, or UV light, is electromagnetic radiation from the sun. We can’t see it, but it penetrates the earth’s atmosphere and reaches your skin and eyes in the form of UVA and UVB waves. These harmful rays can do nasty damage in any season, and there’s no place on earth where you’re immune. Don’t think you’re safe in the shade, either: Wear those sunglasses on overcast days, too, since UV light is coming through even when the sun is hidden behind the clouds.
Long Exposure to UV Radiation Can Damage Your Eyes
Briefly exposing an unprotected eye to UV rays usually won’t cause any symptoms. But prolonged or intense UV exposure without eye protection (including to the sun, welder’s arcs, snow and tanning beds) can cause a condition called photokeratitis. We know that repeated exposure to UV radiation without adequate eye protection can result in permanent eye damage.
Ultraviolet Eye Protection Matters
UV400 protection — which is to nearly 100 percent protection from harmful ultraviolet rays — can protect your precious peepers for a lifetime. Investing in sunglasses that are labeled UV400 blocks 99 to 100 percent of UV light. This rating ensures that all light rays with wavelengths up to 400 nanometers, including both UVA and UVB rays, are blocked out.
Our sunglasses here at Blue Lightning comes with UV400 Protection as standard, which is built directly into the lens, meaning it won’t fade over time!
What are Polarized Lenses & How Do They Work?
Polarized lenses use a special film to further filter reflected light and reduce glare from smooth surfaces. How do polarized sunglasses work, and what does polarized mean, you ask? Polarized lenses have a unique chemical film coating that helps eliminate or reduce glare. Glare is caused when light from the sun is reflected off of water or a solid surface. Have you ever noticed when you are out at the beach or lake, the glare reflecting off the water causes blurry vision? When light is reflected off of water or solid surfaces, the reflected light shines back at your eye and is magnified which results in a glare.
Polarized lenses filter the light that comes in from different angles and allow you view objects clearly. Without polarized protection, depth perception is reduced, distorted view and color perception occur, and in some cases, you could be temporarily blinded. Polarization is useful for many outdoor activities including driving, extreme sports, water sports, and fishing.
Better yet, our Blue Lightning Sunglasses include as standard the highest UV400 protection PLUS Polarization. Meaning, the best of both worlds, protect your eyes from harmful UV rays and reduce glare for maximum results. The benefits of polarized sunglasses are endless and can save your vision!
Finally, while road trips are an awesome way to kick back for some weekend chilling, car windows are another culprit, making UV400 + Polarized Sunglasses an essential piece of gear anytime you hit the road. Whatever adventure or action you have in mind, a pair of sturdy Blue Lightning Sunglasses will hold up.
Final Notes
Think of UV protection sunglasses and polarized eyeglasses as sunscreen. UV protection sunglasses are SPF 45 and polarized are SPF 15. The more protection you have, the better care you are taking of your eyesight. Are you ready to protect your eyes this summer with protective fashionable eyewear?
