Maintenance skills of glasses
No matter how expensive the glasses are, they need to be properly used and carefully maintained. Improper use or maintenance, deformation of the frame, friction and burrs of the lens will affect the wearing effect, and even cause damage to the eyes. So, how to maintain the glasses? What should I pay attention to when maintaining? Sophie from Wenzhou Mike Optics will introduce you to the maintenance skills of glasses.
1. When the glasses are not worn, it is best to put them in a eyeglasses case. The surface of the lens should not be in contact with hard objects, especially be careful not to put the temples upward and the mirror surface downwards. Especially the convex lens used by children with hyperopia or amblyopia, the optical center is easy to wear, and careless use of the lens friction stroke burr into a ground glass shape, and even form deprivation amblyopia, bring difficulties to treatment.
2. It is best to wash the lens with water. Use 1-2 drops of detergent to wash the dishes. Rinse it with water after washing, dry it or blot it with a soft paper towel.
3. Wipe with a fiber lens cloth special for resin lenses, and rinse the lens cloth with water. Be especially careful not to wipe it with the corner of your clothes or hard cloth.
4. The habit of taking off and wearing the glasses with both hands should be cultivated. Long-term one-handed removal of glasses can cause the frame to be gradually distorted and deformed, causing the mirror surface to be skewed and even the inclination of the lenses on both sides is different, which causes the lens center to shift and the prism effect appears-affecting vision and vision fatigue. If you do this for a long time, you will not realize it and worsen vision loss. If the frame is too loose, the optical center can be misaligned with the pupil, causing a prism effect and causing visual fatigue.
If things go on like this, if you are accustomed to skewed glasses, you may not be able to accept fully qualified glasses when you change the lens again. Especially young students who wear progressive multifocal lenses for the prevention and treatment of myopia and the elderly who wear near-sighted lenses should pay more attention, because the use effect of progressive multifocal glasses is closely related to the specifications of the frames .
5. Check frequently. If you find that the frame is twisted or damaged, you should go to the optician to repair and correct it in time.
6. If you feel that the effect of correcting vision is not as good as before, you should find the cause and re-optical glasses in time.
