Why do my lenses always have scratches after not wearing them for long? So we not only need to ask, where did these scratches of the cheapest eyeglasses come from? So how do you wipe off dirty lenses?

Most of them use clothes and napkins to wipe the lenses at any time, not only to wipe but also to use wrist strength, constantly drawing circles to wipe. Every day, every year, your lens scratches are getting more and more.

The surface of resin lenses is generally prone to static electricity, which easily absorbs suspended dust and fine sand particles in the air. These fine sand particles and dust particles will adhere to the surface of the lens.

Not only is the surface of the lens prone to absorbing dust and sand particles, but clothes and napkins are also prone to getting covered in dust. So, if you wipe the lens with a cloth or napkin as soon as it gets dirty, it's like using sandpaper to scrub the lens. So, the surface of the lens was successfully covered with scratches.

A windshield waterproofing agent specifically designed for wipers can also be used to eliminate scratches on glasses.
