How to Protect Eyewear Lenses from Scratches.

Posted by Liz on

Get sunglasses with glass lenses. Glass is known not only for its outstanding optical properties, but also for the scratch-resistance. A lot of eyewear brands offer their signature glass lenses – Serengeti and Ray Ban are some of them. If you need vision correction, some eyeglasses frames can be fitted with Rx glass lenses as well. Though I would not recommend glass if your eyeglasses prescription is high as the lenses will be thick.

Some lens materials like polycarbonate have scratch-resistant coating built-in, some materials like CR-39 don’t. CR-39 requires an additional anti-scratch coating to be applied on top of the lens. If you buy sunglasses, you can check with a sales rep what the lens material is and if the lenses have anti-scratch protection. When buying prescription eyeglasses, you can request an additional anti-scratch coating.

Use a cotton lens cloth to clean the lenses. Avoid rubbing them with a paper towel as it can leave micro-scratches on a lens. Also try to keep your sunglasses in a protective case when you are not using them. A good quality pair of sunglasses or eyeglasses from a decent brand usually comes in a protective case or a pouch and is accompanied by a cleaning cloth.

If you take a good care of your eyewear, it will leave longer.
