2. Color: It is suggested that the color of the frame should not be too bright, otherwise it will affect vision, especially for sports with high reaction requirements, which may easily lead to illusion.
3. Anti-fogging: The ventilation effect is better, which avoids the possibility of factors causing fogging of lenses.
4. Safety: the picture frame must have the functions of corrosion resistance, anti-falling, anti-aging and parts not falling off; The elastic band has good elasticity and toughness, and will not loosen or slip after being worn for a long time. It is easy to replace and clean.
5. Design: ergonomic, high comfort and broad vision; The damping function is remarkable, such as adding a silicone layer to the frame and using soft rubber on the wing.
The frame of a basketball mirror is generally different from ordinary glasses. For example, the material must have super impact resistance, and it is best to use materials with good toughness such as PC and polypropionate; The color should not be too bright, otherwise it will affect vision, especially in sports with high reaction requirements, which is easy to cause false perception; In addition, the most important thing is safety. The picture frame must have the functions of corrosion resistance, anti-falling, anti-aging and parts not falling off.

Some precautions for use:
1. It's the first time to use it, and my eyes will feel uncomfortable because of loneliness. Wear it after receiving it, and walk every morning and evening for 10 minutes, usually about a week.
2. Anti-fog can be done by yourself. We usually put a little detergent on the lens, leave it for ten minutes, and then clean it with a dry paper towel. Don't wipe off that layer of oil completely, so it can prevent fog for a certain period of time! Vaseline can also be substituted.
3. After playing the ball, wash the glasses frame with water in a ventilated place to dry, and store it in a pressure-resistant mirror box, which can increase the service life of silicone.
Some key points of glasses:
1. lens choice I choose a PC lens that won't break. The advantage of PC lens is that it will not break or crack, which can ensure the safety during strenuous exercise.
2. Because the design of this kind of glasses pays attention to streamline, which is different from the optical glasses we usually use, we will reduce some myopia degrees when matching the film, so that we can adapt to this pair of sports glasses faster and better.
Fog is the biggest drawback of this kind of glasses. Because sports glasses pay attention to safety, there is a thick silicone pad on the inside of the glasses, which greatly compresses the space between the eyes and the frame. When the space is small, it is easy to accumulate the heat emitted by the face. In spring, autumn and winter when the temperature difference is large, the glasses will fog after a few minutes of basic movement.
