The Reflective Coating For Lens

A common issue with prescription glasses is 'back-glare' which is the light hitting the rear of the lens and bouncing straight into the eye. Therefore, anti-reflective coating improves the visual quality, preventing 'back-glare', and cosmetic appearance for the wearer.Anti-reflective, or AR, coating is applied to the front and rear surface of the lens to eliminate residual reflections on the lens surfaces. Some anti-reflective coating also has scratch resistance properties as standard to protect your lenses against unwanted scratches.
Extensive exposure to the sun's UV rays can cause disorders such as cataracts and muscular degeneration. UV400 Protective reflective coating is a coating applied to the front and rear surface of the lens to eliminate residual reflections on the lens surfaces, and to protect your eyes from the sun's harmful rays. This protective coating is particularly recommended for anyone working outdoors in bright sunlight.
Unfortunately no glasses are ever absolutely guaranteed to never have scratches. However, one can have a scratch resistant coating applied to the front and rear surface of the lens to help prevent scratches. This coating will increase the life of your lenses by reducing the wear and tear and by providing you with better vision and improved cosmetic appearance.Super reflective coating is the ultimate four-in-one coating providing the better value for money out of the coatings available. The coating is applied to the front and rear surfaces of the lens, and has anti-reflective properties which eliminate residual reflections on the lens surface that reduce clarity of vision. Super duper coatings come with enhanced scratch resistance and include UV400 protection. This coating has the added advantage of preventing water, dirt and greasy smudges from sticking to your lens surface so keeping them even cleaner.
