finally, clean the water stains on the lens surface with a mirror cloth in one direction, and do not wipe it back and forth or rotate it.
The advantages of this method are low cost, clean lenses and little damage to glasses, but the disadvantages are that there are many steps, the nose pad and other parts cannot be thoroughly cleaned, and sometimes the cleaning conditions are not available.
2. Cleaning with mirror wiping paper
The mirror wiping paper is made of non-woven fabric with alcohol, surfactant (detergent), water, etc., which can effectively dissolve the oil on the lens, and can quickly complete the ideal mirror wiping process to a certain extent, and also reduce the possibility of scratching the lens.
There are many brands of mirror cleaning paper, such as Zeiss, Kobayashi, and Essilor. Basically, the effect will not be very different. Just go to Zeiss and Kobayashi directly. Considering the cost performance, Taobao's domestic brands can use air blowing to blow off the dust on the surface of glasses and reduce the dust. Just wipe the lenses with your fingers and across a single layer of mirror cleaning paper.
The advantages of this method are simple operation and clean lenses, but the disadvantages are high cost, and it is impossible to thoroughly clean nose pads and other parts.
3. Using ultrasonic cleaning machine
The working principle of ultrasonic cleaning machine is that the object vibrates by generating ultrasonic waves, and the high-frequency vibration causes the liquid molecules to have a "cavitation effect", which destroys the adsorption of dirt on the lens surface, leaves the lens surface and disperses them into the cleaning solution.
