Abstract: color changing myopia glasses can effectively resist ultraviolet and glare and protect the eyes. The reason for color change is that light sensitive substances such as silver chloride and Aohua Silver (collectively referred to as silver halide) and a small amount of copper oxide catalyst. How about wearing color changing myopia glasses often? People with myopia need to wear myopia glasses often. Myopia glasses can correct their eyesight. Many people like to wear color changing myopia glasses and think that color changing myopia glasses can protect their eyes from strong light, which is very good for their eyes Yes, so is it good or bad to often wear color changing myopia glasses? Let’s start from the principle of color changing myopia glasses and talk about whether it’s good for the eyes to often wear color changing myopia glasses., Color changing myopia glasses can effectively resist ultraviolet and glare and protect the eyes. The reason for color change is that light sensitive substances such as silver chloride and Aohua Silver (collectively referred to as silver halide) and a small amount of copper oxide catalyst. Whenever exposed to strong light, silver halide will decompose into many black silver particles, which are evenly distributed in the lens. Therefore, the lens appears dim and blocks the passage of light. At this time, the lens will become colored, which can well prevent the light and achieve the purpose of protecting the eyes. However , unlike on photographic films, the silver atoms and halogen atoms produced by the decomposition of silver halide are still closely together. When you return to a darker place, with the promotion of copper oxide catalyst, silver and halogen recombine to form silver halide, and the lens becomes transparent again., Colored myopia glasses can effectively block the light from entering the eyes when the strong light is irradiated, so they can protect the eyes. However, wearing color changing myopia glasses for a long time will keep the eyes in a protected state for a long time, which will reduce the adaptability of the eyes to the strong light, reduce the ability of the eyes themselves, and the color changing glasses will be permanent, It will cause the pupil of the eye to be always in an enlarged state, which is very unfavorable to the eye, resulting in distortion of seeing things and possible iridescence. Therefore, color changing myopia glasses cannot be worn for a long time.,
often wear color changing myopia glasses, okay? People with myopia need to often wear myopia glasses. Myopia glasses can correct their eyesight. Many people like to wear color changing myopia glasses. They think color changing myopia glasses can well protect their eyes from strong light, which is very good for their eyes. Is it good or bad to often wear color changing myopia glasses? The following Xiaobian starts from the principle of color changing myopia glasses and says whether it is good for the eyes to often wear color changing myopia glasses.

color changing myopia glasses can effectively resist ultraviolet and glare and protect the eyes. The reason for color change is that light sensitive substances such as silver chloride and Silver halide (collectively referred to as silver halide) and a small amount of copper oxide catalyst.
Whenever exposed to strong light, silver halide will decompose into many black silver particles, which are evenly distributed in the lens. Therefore, the lens appears dim and blocks the passage of light. At this time, the lens will become colored, which can well prevent light and achieve the purpose of protecting eyes. However, unlike the case on photosensitive film, the silver atoms and halogen atoms generated after the decomposition of silver halide are still close together. When you return to a darker place, with the promotion of copper oxide catalyst, silver and halogen recombine to form silver halide, and the lens becomes transparent again.
and
colored myopia glasses can effectively block the light from entering the eyes when the strong light is irradiated, so they can protect the eyes. However, wearing color changing myopia glasses for a long time will keep the eyes in a protected state for a long time, which will reduce the adaptability of the eyes to the strong light, reduce the ability of the eyes themselves, and the color changing glasses will last forever, It will cause the pupil of the eye to be always in an enlarged state, which is very unfavorable to the eye, resulting in distortion of seeing things and possible iridescence. Therefore, color changing myopia glasses cannot be worn for a long time.
