Hi, when should I change the lenses of E80? How should I know?

But how do I know it’s time to change?

Under normal circumstances, it is enough to clean the protective lens. If the protective lens is burned, it needs to be replaced. Burned protective lenses are usually caused by not cleaning the lens in time, causing the lens to absorb the laser and generate high temperature and burn.

Hi Jim,

Unfortunately I did not clean my lense in time and now it has a burn mark in the middle of it. Can I please get the video on how to change the lense?

Thank you,
Brendan
