Flat window manufacturers for you：In the process of lens installation and cleaning, any stickiness, even nail marks or oil drops, will improve the absorption rate of the lens and reduce its service life. Therefore, the following precautions must be taken:
1. Never install lenses with bare fingers. Wear fingertips or rubber gloves.
2. Do not use sharp instruments to avoid scratching the lens surface.
3. When taking out the lens, do not touch the film, but hold the edge of the lens.
4. The lens should be put in a dry and clean place for testing and cleaning. A good worktable surface should have several layers of cleaning tissue or paper swab, and several pieces of cleaning paper.
5. Users should avoid speaking above the lens and keep food, drink and other potential pollutants away from the working environment.
