WHAT IS, -AND HOW TO STORE A LIGHT ADJUSTING LENS PRODUCT
Light Adjusting Lenses darken as the brightness of the sun dictates. Darkest on bright days, clear on overcast days.
True Light Adjusting lenses have millions of molecules of substances such as silver chloride or silver halide embedded in them. The molecules are transparent to visible light in the absence of ultraviolet (UV) radiation, which is normal for artificial lighting. But when LA lenses are exposed to ultraviolet rays, as in direct sun light, the molecules undergo a chemical process that causes the molecules to change their shape. The new structure of the new molecules absorbs portions of the visible light, causing the LA lenses to darken. The number of molecules that change shape varies with the intensity of the UV rays. Studies have shown that the transition works even better in cold conditions.
Being UV-reactive they will not react to artificial light so will remain clear when worn indoors, even in bright conditions, providing the optimal level of visibility both indoors and outdoors. Please be advised that some motorcycle helmets comes with visors, with UV filter, and most cars have UV filter in the windows. This means that the molecules can´t absorb the UV rays and the lenses won´t darken.
To get the best out of your Light Adjusting lenses, which have a tint adjustment life of 2 years, we recommend that you always keep your LA lenses stored in the case, when not in use. Leaving the LA Lenses out in the open, exposed to ultraviolet rays, at all times, will decrease the tint adjustment life significantly.
ANTIREFLECTIVE OR ANTI-REFLECTION (AR) COATINGS
Antireflective or anti-reflection (AR) coatings are a type of optical coating applied to the surface of lenses to reduce reflection. This improves the efficiency of the eyeglasses since less light is lost. The primary benefit is the elimination of the reflection itself, This coating on eyeglass lenses improves both your vision through your lenses and the appearance of your glasses.
The result is that you'll see a reduction in glare, annoying reflections and halos around lights. This is a great safety benefit when you're driving at night.
Also, anti-reflective coating reduces both internal and external reflections on the lenses themselves, creating a nicer cosmetic appearance. Internal reflections appear as rings that make lenses look thick. External reflections mask your eyes from a clear, complete view when someone is looking at you. So with an anti-reflective coating, reflections are eliminated and eyeglass lenses look thinner or non-existent, and your eyes are more visible so you can make better eye contact with others.
Anti-reflective coating is also beneficial when applied to the back surface of lenses in sunglasses because it eliminates reflections of sunlight into your eyes from the lenses when the sun is behind you. (Since the purpose of sunglasses is to reduce how much light enters your eyes and because you aren't concerned about making eye contact with others when wearing shades, there is no benefit to having AR coating applied to the front surface of sunglass lenses.)
When cleaning AR-coated lenses, use only products that your optician recommends. Lens cleaners with harsh chemicals may damage the anti-reflective coating.
Also, don't ever attempt to clean AR-coated lenses without wetting them first. Using a dry cloth on a dry lens can cause lens scratches. And because anti-reflective coating eliminates light reflections that can mask lens surface defects, fine scratches will be more visible on AR-coated lenses than on uncoated lenses.
Wiley X Europe offers several different mirror coatings for sunglasses both with and without prescription lenses. Mirror coatings are pure looks, it has no visual effect when using the glasses, and it is individually what people prefer. Read more about the different mirror coatings below.
Silver Flash is a weak mirror, where it is possible to catch a glimpse of the eyes through the lenses. The Silver Flash is not available with prescription lenses.
WX Mirror is an intense mirror coating, which works as a mirror image and you cannot see the eyes of the beholder. This coating is not available with prescription lenses.
Soft Mirror is developed by our prescription lens manufacturer SHAMIR, and it is a combination between the Silver Flash and WX Mirror with an inclination to Silver Flash.
Soft Mirror comes in four different colors: Gold, Silver, Blue and Emerald Green and it is only available with prescription eyewear.
