Solid Tints: Plastic lenses bathed in specialty lens tints can take on any color shade and density. The lens actually absorbs the tint color into the lens material, so there is no risk of fading or wash out. Tint density is defined as a percentage, where 0% is completely clear, and 100% permits no light to pass through. A 10% to 20% tint is used for a “fashion” tint, and a 50% to 80% tint is used for outdoor protection from the sun. You may choose your own lens color, and customize your sunglass lenses to your specific needs and applications. Choose from blue, Green, Grey, Brown, Yellow and Amber colors. Amber colored lenses block all blue light and make your surroundings look yellow or orange. The tint supposedly makes distant objects appear more distinct, especially in snow or haze. For this reason, amber sunglasses are popular among skiers, hunters, boaters and pilots.
Photochromic Glass Lenses: A photochromic glass lens automatically darkens in bright light and becomes lighter in low light. Most of the darkening takes place in about half a minute, while the lightening takes about five minutes. They come in a uniform or gradient tint. Although photochromic lenses may be good UV-absorbent sunglasses (again, the label must say that), it takes time for them to adjust to different light conditions.
Photochromic Plastic Lenses: The original plastic photochromic was introduced in 1991 and has since become very popular. This lens isn't designed to take the place of sunglasses. They are designed for people who normally like a tint in their lenses and prefer the light weight of plastic lenses. The added advantage is that they do change to existing light conditions giving more of a tint enhancement. All plastic photochromic lenses come with scratch resistance coating, 100% UVA and 99.8 % UVB protection. They are continually becoming available in more lens styles. Please ask us for a demo.
Polarized Lenses: Polarized lenses have the benefit of filtering out reflected light and glare off water, pavement and snow. This type of lens works great for fishing, boating, driving or any other glare intensive activity. Polarized lenses are the best way to eliminate both glare and UV light. The principle of a polarized lens can best be described by observing the use of a Venetian blind. The blind blocks light at certain angles, while allowing light to transmit through other angles. Polarization is achieved by shutting out 100% of undesirable light and allowing 100% of desired light through the lenses. Many polarized lenses feature Anti-Reflective coating on the back of the lens for even better clarity and reduced back glare. Anti Reflective Coating is an extremely thin layer of film that is deposited on either the front or the back surface of the sunglass lens that virtually eliminates reflections from the back of the lens. Polarized lenses come in variety colors. The most popular colors include dark green and dark gray both at 80%.
