What are the disadvantages of colorful led glasses

Color contact lenses will have a certain impact on the pupil light transmission. The human pupil is with the intensity of light automatically adjust the size of the color contact lenses, and the size of the non-colored area is fixed, so in the evening when the light is dark, the pupil dilation will certainly lead to the colored area blocking the visible area, at this time, people see things is partially shrouded in color and some blurred. Even in stable light, when we are reading or observing objects, colored contact lenses can cause vision fatigue due to the movement of the eyeball position blocking the eye's view. Since the effect of coloring substances on the cornea and vision when worn on the eyes is mainly caused by the fact that the lenses have to move with a person's blinking and by the sliding of the lenses themselves, some sensitive people may also experience conditions such as corneal skin damage. The eye is different from other parts of the body, it has no blood vessels, mainly through the absorption of oxygen and water in the air to promote metabolism and maintain their own nutrients, wearing color contact lenses for a long time is the same as preventing the eye from fully absorbing nutrients. So no matter myopic or not, wear these glasses as little as possible; or only use them occasionally on special occasions, don't wear them all the time from morning to night as you do with ordinary myopic lenses. The color of colored contact lenses is infiltrated into the lens, if the production process is not good enough replacement, there may also be a risk of material leakage later. Therefore, we should go to the regular professional medical institutions for professional examination, and purchase those qualified products produced by manufacturers through the test; at the same time, it is best to have professional equipment every six months to the optometry center for review. In the daily wear, but also pay attention to health, the lens to regular care and replacement. Wear colored contact lenses with caution Contact lenses were originally myopic patents, but now for the pursuit of fashion for young people, it has become a kind of decoration. Nowadays, there are colored contact lenses, after wearing them, the eyeballs become green, blue, yellow, purple and even some have patterns. The color of the eyeballs is changed, but will the eyes be affected? Zhao Jialiang, chairman of the Chinese Medical Association's ophthalmology branch, pointed out that due to the special structure of colored contact lenses, they can have unpredictable effects on vision. Zhao Jialiang said, after wearing colored contact lenses, it may cause some problems when looking at things at night, because the transparent area in the center of colored contact lenses is fixed, and the size is also fixed, it can't change with the strength of the light like the pupil of the eye to become bigger and smaller, so in the dark light, wearing colored contact lenses to see things will be a little blurred. Even in stable light, when we are reading or observing objects, colored contact lenses can cause vision fatigue because the movement of the eyeball position blocks the eye sight. Zhao Jialiang also suggests that because the eyeball is different from other parts of the body, it has no blood vessels and mainly promotes metabolism and maintains its own nutrition by absorbing oxygen and water from the air. Wearing these glasses for a long time is tantamount to preventing the eyeball from fully absorbing nutrients. So whether you are nearsighted or not, you should try to wear these colored contact lenses as little as possible
