What To Do with Old Glasses?
You can also choose to send your old glasses to others. You can ask your friends or ask around your social network to see if someone needs a pair of glasses. Then give them the old glasses.

If the only reason to give away your old glasses is that they are broken, you can try to repair them. After that, they can be useful.
The anti-reflection principle of the anti-reflection film
Anti-reflection Coating, known as anti-reflection membrane, is called anti-reflection coating in English, or AR membrane for short. The basis of anti-reflection is the wave and interference of light. The principle is: Two light waves with the same amplitude and the same wavelength are superimposed, then the light wave amplitude is enhanced. The two wavelengths and amplitudes are the same, but the superposition of wavelengths with different wave paths (similar to dislocation) cancels each other out. Therefore, the anti-reflection film plated on the surface of the lens uses this principle to make the reflected light generated by the front and rear surfaces of the film layer interfere with each other, thus canceling each other and achieving the effect of reducing reflection.
Why My New Glasses Give Me a Headache?

The Acetate Spectacle Frame
The sheet spectacle frame is made of a high-tech plastic memory sheet. The current sheet material is mostly acetate fiber, and a few high-end frames are propionate fiber. The acetate fiberboard is divided into injection molding type and pressing and polishing type. The injection molding type is made by pouring in a mold. The plate frame is also suitable for people with a high number of heights because the frame is larger and can withstand a high number of lenses.
Do blue light blocking glasses work?
Usually, blue light blocking glasses are yellowish, and this obvious color shift can cause serious visual fatigue. The aggravation of visual fatigue will not control myopia and will accelerate the progression of myopia. The most important thing is that some parents have the misconception that blue light blocking glasses can control myopia. If they allow children to use electronic products without guidance and control, myopia will definitely progress. During online classes, the best way to avoid the blue light damage of electronic products should be to relax their eyes between two classes. You can learn from the 20-20-20 rule recommended by the American Academy of Ophthalmology, which is to look at objects 20 feet away for at least 20 seconds for every 20 minutes. Also, you can take a break of 10-15 minutes between each online class. You can choose to look at the distance, play table tennis at home, or have fun with parent-child interaction. In this way, the tense shoulder and back muscles can be relaxed while the eyes are relaxed and rested. Not only can it prevent and control myopia, but it is also very helpful for improving the efficiency of learning. Teach children to blink their eyes more consciously when watching the electronic screen, and use a warm wet towel to heat the eyes during rest. A humidifier can be used at home to increase the humidity of the surrounding environment. This can effectively prevent dry eyes caused by looking at the electronic screens for a long time.
Disadvantages of progressive lenses
Wearing progressive multifocal glasses for the first time may cause slight dizziness and shaking when walking. Be careful when moving up the stairs. The perception of space changes, the perception of the distance of the object, and the perception of depth have changed. New wearers should not drive immediately and do vigorous exercise. When you look close, you need to turn your eyes down, and your eyes are mildly uncomfortable. Seeing the object through the blurred vision area around the lens, the object becomes blurred. Therefore, when new wearers look at things, turn their heads more, turn their eyes less, try to use the far-distance zone, the near-distance zone, and the middle-distance zone to see the object.
