Optical lens cleaning and maintenance

1. It is best to use a small soft brush to wash with clean water to remove the dirt in the seam. When wiping the lenses, use the glasses cloth to wipe in one direction, do not rotate in circles.

2. Generally, the dust accumulation of glasses for a long time is more serious. You can use a professional glasses cleaning cloth to wipe them first, or there are professional ultrasonic cleaning glasses outside now.

3. Because hands often touch the lens, it will be oily, so it is recommended to use detergent to clean it. After washing with detergent without adding water, rinse with water, and then wipe with soft paper or glasses cloth.

4. When cleaning glasses, it is best to hold the bridge of the nose of the frame with one hand, and gently rinse the dirt of the glasses with the other hand.

5. Generally speaking, the lens can be cleaned once every 2 days.
