Pure Coat is Scratch Resistant or Scratch Proof coating applied to the lenses. It helps to prevent minor scratches that can easily happen to a regular lens. These minor scratches can damage the surface of the lens and impair vision. Pure coat acts as a protective layer thus making the lenses more durable.The coating does not interfere with how the lenses function and does not affect vision, but creates a permanent bond with the lens that reduces the appearance of hairline scratches which is common to eyeglass lenses.
Pure coat lenses are better than uncoated lenses in several ways.
Anyone can benefit from pure coat lenses, but there are people who need them more than others. If you live an active lifestyle - play sports or engage in outdoor activities regularly, for example - then you need eyeglasses that will be able to withstand physical contact and exposure to the elements.
If you tend to leave your glasses lying around unprotected, or if you don’t usually use the case they come in, then you definitely need scratch-resistant lenses.
Pure coat lenses are particularly suitable for the elderly since they are more likely to forget to take care of their eyeglasses properly. They may overlook using proper cleaning materials. Furthermore, they tend to accidentally drop their glasses.
Kids are probably the ones who need anti-scratch lenses the most. They usually aren’t too concerned about taking care of their eyewear. If they have scratch-resistant lenses, you don’t have to worry about replacing their eyeglasses every time they get too excited in the playground or shove their glasses unprotected into their backpack pockets.
