I believe many myopic friends feel the same way. Lenses are prone to oil and a layer of dust. If you don’t pay attention, hard rubbing can easily scratch the lenses. So the question is, where does the oil on the lens come from?
Since spectacle lenses are mostly made of plexiglass or resin (grease has a strong adsorption effect on glass), grease and plexiglass are soluble in each other and have a relatively large adsorption force. In addition, our skin will secrete oil, and the oil vapor will be adsorbed on the spectacle lenses. It is not noticeable at first, but over time, a thin layer will accumulate.
The thin layer of grease will be stained with dust in the air. These dusts are made of various materials. If the hardness is greater than that of spectacle lenses, marks will be left on the lenses if you are not careful when wiping your spectacles.
1. What should I do if it gets dirty?

A representative from office workers said: I have worn glasses for more than 30 years. Before, when my glasses got dirty, I would wipe them with glasses cloth, toilet paper or the like (it seems very professional, but it is not scientific).
Correct cleaning steps
1. Rinse the lens with clean water first, rinse the lens with clean water, rinse the lens with clean water, and remove the dust on the surface of the lens.
2. Apply professional glasses cleaning solution to the glasses, slowly rub the surface of the glasses with your fingertips to create foam, and rinse.
Attention! Do not use alcohol, hand sanitizer, dishwashing liquid and other cleaning agents, otherwise it may accelerate the aging of the lens film.
3. After rinsing, shake off the water, and then use a special lens cloth to gently absorb the water.
Attention! Glasses are not scratch cards, and they will not work miracles with great force.
It is easy to get foggy in winter
Today is the beginning of winter, and the weather is getting colder day by day. Have you ever noticed that when you eat noodles, wontons and other hot and spicy things, there will be a The feeling of seeing flowers in the smoke?
Scientific analysis of fogging
At low temperatures, water vapor will condense into smaller particles and attach to or around the lens. When encountering higher-temperature air, small solid water vapor particles will liquefy or evaporate, causing the lenses to fog up and affect visual clarity.
How to prevent glasses from fogging
Buy anti-fog glasses
Patented anti-fog lenses are generally coated with a special hydrophilic anti-fog film layer , can effectively reduce the chance of fog generation, and the anti-fog effect can reach 85%. However, the anti-fog effects of different brands of anti-fog lenses may be different. But most anti-fog glasses are sports and functional.
Use a special anti-fog cleaner for glasses
A special anti-fog cleaner for glasses can form a dense, ultra-thin, ultra-transparent biological coating on the surface of the lens to convert fog droplets into Form a transparent microglass layer to achieve the purpose of anti-fogging. In fact, this technology first appeared in car rearview mirrors.
Make your own anti-fog water
Mix 30 ml of glycerin and 10 ml of soap solution, then add a few drops of turpentine and stir evenly. When using, apply this anti-fog water on the lenses and then wipe them dry with a glasses cloth. Generally, the anti-fog effect can last for 3-4 hours.
