4 Things to Know About Scratches on Glass Mousepads

Tiny scratches from normal use won’t affect tracking Modern mouse sensors read surfaces at a microscopic scale and need consistent texture to track movement. Tiny surface scratches from mouse feet are too shallow and random to disrupt that.

Glass scratches are just light scuffs Glass is hard, so normal-use scratches barely change the surface. They don’t alter the texture enough for the sensor to notice.

Deep gouges or peeling coating can cause problems Dropping something heavy can create deep gouges that disrupt tracking. Coated glass pads with peeling coating can also confuse the sensor.

Only scratches you can feel with your fingernail matter If a scratch is deep enough to catch your fingernail, it might cause tracking skips. But that kind of damage doesn’t come from normal mouse use.
