• All About Lens Coating and Tints

    Wohl offers a variety of tints and coatings, from a multi-layer anti-reflective coating to minimize glare, ultraviolet blockers to protect your eye health, as well as polarized sunglass lenses to offer the ultimate in comfort and vision while outdoors.

    Purchasing eyeglasses should be looked upon as an investment, so let's think and talk about your lifestyle needs carefully when picking out lenses. Do you spend much time outdoors? Are you active in sports? Do you drive a lot? Are you on the computer a lot?

  • Coatings on Lenses

    • Scratch Resistant­ Coating — Generally a good idea for all lenses and comes with 95 percent of plastic lenses. With this lens coating, the lenses are treated front and back with a coating that creates a harder surface on the lens, resulting in more scratch resistant lenses and all around more durable glasses. Please remember, there is no such thing as scratch-proofing your lenses. A scratch-resistant coating is a cost-effective investment in your eyeglasses. Once lenses become scratched, they should be replaced.
    • Anti Reflective Coating — Also known as an anti-glare coating is often bundled with high-index and HD lenses. This AR Coating is a thin coating that helps eliminate the amount of light that reflects off the surface of your lenses. If you have trouble seeing properly when on a computer, driving, and at night, consider them. In the past, Anti-glare coatings were difficult to clean and they were smudge-prone; anti-smudge/anti-fog technology has solved that problem.
    • Ultraviolet Protection Coating — Anti-UVA/UVB lens coating is a good idea for everyone because the UV rays from the sun may boost your risk of cataracts. It is extremely important to protect yourself from the long-term damages of UV rays from sunlight.

      UVA rays can penetrate all the way through to your retinas, which can result in long-term damage and the eventual development of conditions like cataracts (a clouding of the lens that reduces vision), macular degeneration (the deterioration of the central part of the retina that can cause a loss of central vision and lead to eventual blindness), or a thickening of the sclera (the white of the eye) which can then lump up and leave you in great discomfort.

      UVB rays penetrate less deeply and are the more intense of the two. When it comes to your eyes, the cornea is the most affected by UVB rays, and exposure to UVB rays can lead to short-term damage such as the development of a condition known as snow-blindness, an inflammation of the cornea that is really sunburn in your eye.

    • Photochromic Coating — Darkens in sunlight and shields you from UV rays. It’s helpful if you’d rather not carry separate sunglasses. Many do not think this coating does not become as dark as they would like outside. 
    • Blue Light Blocking Coating — Might reduce exposure to computer screens’ LED light. (Some studies suggest that overexposure can damage the retina and increase the risk of age-related macular degeneration and cataracts.) 
  • Color Tints

    Why Use Color Tints — Different lens tint colors provide an array of different looks and cause your eyes to react differently to varying light making certain colors more suitable for certain activities and conditions.

    Color tints can be for aesthetic reasons, but certain color tints can be applied to sunglasses (as well as regular eyeglasses) for aid in things such as night driving, dyslexia and even color blindness.  For example, yellow or orange color tints filter blue light and are used in sports eyewear for cycling, hunting, shooting, skiing, snowboarding, snowmobiling, indoor basketball, handball, racquetball, tennis.

    Gradient Tints — Gradient tints are tints that are darker on the top half of the lens and then lighter on the bottom half. When looking through the top half, it’s tinted just like regular sunglasses. However, when looking through the bottom half, the glasses are crystal clear like regular glasses. This tint is a great lens coating option if you spend a lot of time reading, writing and doing close-up activities outdoors.
