A lens treatment is a special additive that either bonds with the lens, or is built into the lens during the lens manufacturing process. Lens treatments are available as individual additions to lenses, and are also commonly bundled into single lens products for convenience and maximum benefit to your eyes.
In addition, Blue Light coatings can be applied to lenses that block Blue Light. BluTech Lenses are special lenses specifically designed to selectively filter out blue light, enhancing visual comfort and minimizing eyestrain. These lenses boast a special state-of-the-art filtering agent within the lens material itself that duplicates elements in the eye, called ocular lens pigment and melanin, which the body naturally produces on its own, and which help filter out just the right amount of blue light entering the eye to protect against unfettered blue light penetration, while allowing proper visual contrast.
Recharge is another cutting edge option to help cut down on the harmful effects of blue light. HOYA is the advanced eye care company that produces these lenses, which reflect up to 30% of harmful blue light away from the eye. Between the filtering effect of BluTech and the reflective properties of the Recharge coating, a large percentage of otherwise very harmful blue light never reaches the eye. This is an extremely important element in the long term health of your eyes.
In addition, Conant Lens Inc. has recently launched a new ophthalmic lens material (UV++®) that helps protect eyes from both ultraviolet rays and blue light. UV++® is made from a blue block material which reduces blue light.
