After wearing glasses for a long time, your glasses are dirty, do you often open the glasses case and take out the glasses cloth to wipe your glasses? This is a bad habit, your lenses will be full of scratches in a short time.
The maintenance and cleaning of the lens should be mainly washed with water. It needs to be rinsed with clean water. Do not use hot water, and do not wipe it directly with a dry cloth or paper towel, which will damage the lens.
If you wear glasses for a long time, there are many tiny dust particles on the lens. If you dry wipe, the cloth will rub these dust particles back and forth on your lens. To put it bluntly, it is the same as sandpaper. Use sandpaper to rub back and forth on the lens.
Over time, the coating layer of the lens will be wiped off.
For the oil stains and fingerprints attached to the surface of the coating layer, we need to use glasses cleaning agent. You can also use detergent but do not use facial cleanser or hand sanitizer. Certain chemical components contained in it may have a corrosive effect on the coating layer, which will cause the coating layer to fall off over time.
Therefore, it is recommended to clean the lens with clean water or a special lens cleaning solution at ordinary times.
Once the lenses are clean, rinse the lenses under a calm stream of water.
But there will still be water droplets on the lens at this time?
Put the lens vertically (put the lens upright), let the water flow evenly from both sides of the lens, and move the lens slowly so that the lens is almost parallel to the water column to wash the lens in a "scanning" manner. Generally, there will be no water droplets or any fingerprints left, so the lens will not be polluted again when drying, just take a paper towel or lens cloth near the frame after cleaning to absorb the remaining water droplets.
If you feel that it is too troublesome, the current optical shops generally provide free cleaning services, you can go directly to the optical shop to wash the glasses.
For friends who are not short of money, you can buy a small ultrasonic cleaner. The price of ultrasonic cleaners ranges from more than one hundred to several hundred, and they are sold online.
It is recommended to read the instruction manual for specific instructions, but it needs to be reminded that some glasses cannot be cleaned by ultrasonic waves, such as crystal lenses, polarized lenses, and tortoiseshell frames, etc. cannot be cleaned by ultrasonic waves.
If it is inconvenient to go out, I recommend a disposable paper that is specially used to wipe the lens. One-piece package, easy to carry, does not wear the lens, and the camera lens can also be used.
