How to clean and maintain optical frames?
1. Use ultrasonic cleaning to remove the dirt inside by vibration. Generally, optical shops have this service, which is basically free.
2. When the lens slot of the full-frame spectacle frame is dirty, you can unscrew the screw by yourself, take off the lens and wipe it clean with a paper towel.
3. If the screw is loose, please take it to the optician and tighten it in time, otherwise the lens will easily fall on the ground and break. Don’t handle it arbitrarily.
4. Cosmetics or cosmetics and other cosmetic products with chemical composition can easily fade the frame of the frame. Please wipe it off with a cloth or paper for glasses.
5. Most of the glasses are gently folded from the left side of the lens. If you hardly fold it from the right side, it will cause the frame itself to be unbalanced and skewed, making it uncomfortable for you to wear.
6. In order to give full play to the correct function of the glasses, the optical center of the lens is made in the part that suits your eyes, please wear it in the correct position.
7. Wipe dry with a cloth for glasses. Do not touch the lens with hard objects. Do not wipe the lens with your fingers. Please wipe the lens with a clean cloth to reduce lens wear.
8. Do not put the convex surface of the lens down. When not in use, try to put them in the eye box. If you are not wearing the glasses, please wrap the glasses with lens cloth and put them in the lens box to avoid damage.
9. Please hurriedly place the infant next to you when you are resting.
