LENS TECHNOLOGY OPTIONS
Listed below are our most popular lens treatments. There are many others. Dr. Akamine Davidson will discuss them with you during your examination to determine which would be the most appropriate for your visual needs.
PureCoat Anti-Reflection Coating – Anti-reflection coatings eliminate the reflections of light from the surface of the lens allowing for clearer, crisper vision. If you were looking through your windshield at night, you might be able to see. However, if you were to open the window to look outside, everything would be much clearer. That is because you are not looking through glass that has all of the reflections on it. The anti-reflection coatings eliminate the reflections on the lens, allowing you to experience clearer, crisper vision.
PureCoat has a base layer that is rated the hardest, most scratch resistant coating on the market. Also part of PureCoat are multiple, microscopically thin layers of anti-reflection material, which are added to the lens. The result is an extremely clear lens, which is very difficult to scratch.
Not all anti-reflection coatings are created equal. The inexpensive, lesser quality coatings are only applied to the front surface of the lens and will smudge with oils, are difficult to clean and will peel or scratch easily, thereby degrading your vision. We always use the industry’s best coating and warranty it against scratches or defects for a year.

Transitions- Transitions is a photochromic lens technology, which means that it is clear indoors and at night, and when exposed to UV light from the sun, darkens. The lens darkens very quickly and takes a few minutes to clear once you come out of the sun.
These lenses are very convenient for many people who just desire to have one pair of glasses for indoor and outdoor use. Because the windshield of the car blocks most of the UV rays from the sun, the lens does not always darken as much as some people desire, while they are driving with the windows closed. For extended driving or a need for darker lenses, we recommend a second pair of polarized lenses.
Polarized Lenses- Polarized lenses block more glare than tinted lenses. When light hits a flat surface and is reflected off of that surface, the light becomes polarized. That means that all of the wave lengths of light go in the same direction. The polarized lens blocks all of the reflected light, plus the tint of the lens uniformly blocks up to 80% of the light entering the eye. So there is enough light to see, but not too much light to cause glare. We highly recommend polarized lenses for every pair of sunglasses we sell.
