UV (Ultra Violet) rays are invisible rays from the sun. Eyes are very sensitive to UVA/UVB light. Exposure to UV light can result in photokeratitis (eye sunburn), conjunctivitis, cataracts, macular degeneration and eye cancer. Look for sunglass lenses that have 100% UVA/UVB Protection. UVA & UVB are the most dangerous to the eyes, since UVC light is blocked by the ozone layer.
Although most sunglasses feature lenses that block 100% UVA/UVB, the sunglass frame itself is as important as the lenses. If you are wearing a pair of sunglasses that feature UV blocking lenses, but the frame doesn't protect your eyes from unfiltered peripheral light, then your eyes are still being exposed to harmful UV rays.
Lets UV Rays In
Dioptics sunglasses and fits over sunglasses feature designs that conform to the principles of Advanced UV Protection®. Advanced UV Protection® sunglasses not only have lenses that block 100% UVA/UVB, but the frames wraparound to block stray light. Advanced UV Protection® prevents the majority of unfiltered light from reaching your eyes since the frames feature extra protection on the top and sides.
Optify™ Lens Technology
Haven’s Optify™ technology boasts polarized, 100% UVA/UVB blocking, scratch-resistant, optical-grade lenses. Its premium olephobic lens coating repels oil, grime and water for maximum visibility and durability.
All our lens tints used in our fits over sunglasses, clipons and sunglasses deliver 100% polarization* and block 100% of harmful UVA/UVB rays, but lens tints do limit the amount of light that is transmitted to your eyes. They can also alter color perception and contrast. All of our lens tints meet or exceed U.S. Food and Drug Administration (FDA) standards and are safe for daytime driving.
*Eyesential® sunglasses are not polarized due to the needed application of anti-fog coating.
Water can leave annoying streaks on sunglass lenses. Hydrophobic and oleophobic lens coatings repel liquids to bead and roll of the surface of your lenses.
Dirt, oil, grime and fingerprints can hinder visibility. Oleophobic and SmudgeGuard™ lens coatings repel oil and grime leaving your sunglasses free of residue leaving cleaner and clearer lenses.
Standard lenses are highly susceptible to micro scratching, even with ordinary use like setting them on the counter or on the dashboard of your car. These tiny scratches build up and compromise your vision and performance. A tough coat makes lenses two times more scratch-resistant than standard lenses. A tough coat offers optimal durability and extended life.
Most of our lenses are scratch-resistant. Although no lens is scratch-proof, a scratch-resistant lens can withstand the wear and tear of daily use without hazing. Hazing is a common occurrence of lenses that are not scratch resistant. Simply placing a pair of unprotected sunglasses in a purse or on the dashboard of a car can lead to many tiny, barely noticeable scratches. The cumulative affect of thousands of minute scratches is called hazing. The lenses begin to lose the ability to deliver crisp, sharp viewing, as the surface of the lens has been clouded with tiny scratches.
Scratch-resistant lenses have a special coating on both sides of the lens. This coating is designed to prevent the surface of the lens from absorbing scratches. The benefit of having a scratch-resistant lens is that the lifespan of the sunglass is increased. Lenses that are not scratch-resistant can perform perfectly for many years, but care must be taken to always place them in a protective pouch or case.
What does “POLARIZED” mean?
When sunglass lenses are polarized it means they eliminate glare. Glare is all around us and can be extremely dangerous, especially when driving or traveling at speed. Glare is generated by any reflective surface. The road, pavement, sand, water, snow, or almost any surface can create glare. Glare can be reflected light from below, above or any angle.
When your eyes are hit by glare, you may have a tendency to squint. If left untreated, glare can eventually lead to eye-strain and fatigue. It can lead to sore eyes and ultimately headaches. Glare is an uncomfortable distraction and will reduce your visual acuity.
The most effective way to eliminate glare is polarization. 100% polarized sunglasses will eliminate glare, allowing you to see things clearly, without any visual discomfort. Polarization works like a set of chemical horizontal blinds...allowing light to calmly reach your eyes in a controlled and organized fashion.
As one of the leading proponents of polarization, we offer a range of polarized lenses in various tints and quality levels. All of our polarized sunglasses, fits over sunglasses and clipons eliminate glare.
