Mirrored Coating: Also called Flash Coating, it is applied to the outside of the lens and can be applied over any base color. New laboratory processes have created coatings that adhere better to the surface of the lens, are less susceptible to scratching, and are available in an expanded palate of colors. Mirror coated lenses absorb anywhere from 10 percent to 60 percent more light than uncoated lenses, depending on the type and degree of coating. The light transmission is further reduced by the base tint of the lens. Due to its reflective property, any mirrored lens will appear darker since it will reflect a certain amount of light trying to reach the eye. A mirrored lens will also add an extra buffer against glare. This makes them ideal for outdoor uses such as skiing. Care and Cleaning: Because most mirror coatings are applied to the surface of the lens, extra care must be taken when cleaning a mirrored lens to prevent scratching and other damage to the surface. Lens cleaning cloths should be used rather than abrasive cotton or paper towels. Dawn dishwashing soap is a good cleaner, but don’t use other household cleaners such as Windex.

Anti-Reflective Coating: This coating can be applied to the outside or inside surface of any lens (clear or sun lens) to minimizing the amount of light reflected by your lenses thus reducing annoying reflections and distracting glare which may cause headaches or interfere with vision clarity. Regular lenses reflect a very small amount of light back into your eye, possibly skewing vision; anti-reflective coating helps to prevent this anomaly. It is best used on the back surface of a sun lens to minimize back glare.

Anti-Scratch Coating: This is applied to the outside of the lens to minimize the likelihood of accidental scratching. This does not make the lens scratch proof, but helps tremendously in reducing fine hair line scratches. All polycarbonate lenses come with an anti-scratch coating.

LENS TYPES

Polarized Lenses: Polarized lenses are unique lenses that work similarly to a Venetian blind. A blind only lets in light at certain angles, which is how a polarized lens works. With the removal of the sun’s glare, objects become more distinct and are seen in their true colors. Reduced glare off water, roads, and other objects make the polarized lens a favorite for water sports, fishing, cycling and driving.

Photochromatic Lenses: These lenses will change color as the light changes. For example, in the bright sunlight, the lenses will be dark however if the wearer then comes indoors, the lens will lighten accordingly.
