1. Wearing finger cots, there are substances on the hand that are easy to corrode the glass surface, such as acid and salt. If you directly touch the optical lens with your hand, it will cause imprints on the optical lens. If you do not wipe it for a long time, it may become permanent stains.

2. Handle with care. Many optical lenses are glass products, which are easy to be scratched, chipped, or scratched. Take the edge of the lens and do not directly touch the translucent surface, even if you wear a finger cot.
3. When not in use, place it on a soft surface. Do not place the bare chip directly on glass, metal, desktop or dirty paper, as the lens is very easy to scratch.
4. If you encounter dust on the surface of the lens, blow it a few times with a clean ear ball to blow the dust off.
5. If you encounter stains or sweat stains, wipe gently with lens cleaning paper or silk cloth dipped in alcohol or acetone.
6. When storing, use clean capacitor paper or lens wiping paper to pack, and place it in an environment with a moderate temperature (appropriately about 23°C) and humidity (below 40%), and place it in a drying cabinet if possible.
7. Do not stack the optical lenses together, and do not overlap each lens.
8. Once it is found to be dirty, clean it immediately, but pay attention to prevent scratches. Dust can easily scratch the lens.
