Foggy lenses are a problem in cold climates and also people that have steamy conditions. An anti-fog lens coating eliminates this issue by avoiding the lens surface from developing condensation. There are fewer choices for anti-fog lenses, because this technology continues to develop. However, an anti-fog coating could be perfect for someone who plays sports or frequently transitions from a cold environment to a warm room.
Luckily, polycarbonate lenses already block out harmful UV rays from the sun. And, unlike various other forms of eyeglass lenses, they don’t require any extra coating for sun protection. Anti-reflective coating (also known as AR coating or anti-glare coating) improves both your vision during your lenses and the appearance of your eyeglasses. Both benefits are as a result of ability of AR coating to get rid of reflections of light from the front and back surface of eyeglass lenses. With fewer reflections, more light passes through the lens to the eye once and for all vision and the lenses look more transparent and attractive.

  • Fog Free could be put on plastic, polycarbonate along with other eyeglass lenses, including high-index lenses and Transitions photochromic lenses.
  • The entire multilayer AR coating stack generally is about 0.2 to 0.3 microns thick, or about 0.02 percent (two one-hundredths of just one 1 percent) of the thickness of a standard eyeglass lens.
  • Reduces glare and allows more light to pass through, enhancing vision and reducing eyestrain.
  • AR coatings also work to reduce both internal and external reflections on the lenses themselves, creating the appearance of a thinner, almost non-existent lens.

work fine without anti-reflective coating, however the relaxation to your eyes and improved vision are often worth it. Regular plastic eyeglass lenses block most UV light, but adding a UV-blocking dye boosts UV protection to completely for added safety. Other eyeglass lens materials, including polycarbonate and most high-index plastics, have 100 percent UV protection built-in, so an extra lens treatment is not required for these lenses. Fortunately, almost all high-index plastic lenses and most sunglasses have 100 percent UV protection built-in. However, CR-39 plastic lenses require a supplementary coating for total UV protection. Eyeglasses with photochromic lenses also block 100 percent UV rays with no need for an extra UV lens coating.
