Contact lenses have become the first choice for people who are not very good at wearing glasses for nearsightedness. But each pair of contact lenses has a “life span”, and many people believe that each pair of contact lenses can be worn for two years, so many people wear a pair of contact lenses for two years before throwing them away. This is likely to lead to cataracts.
Contact lenses have become a fad, which is not only beautiful but also convenient, especially for those white-collar people who are fashion conscious. However, what they may not expect is that wearing contact lenses for a long time to look at the computer not only affects their eyesight, but can also easily lead to cataracts.
The contact lenses are made of polymer materials, although different brands and materials, but all have a common disadvantage, contact lenses in the computer radiation exposure, will gradually decompose and deteriorate, making the original material molecules produce variation. Some of these decomposed small molecules will reach the lens through the lymphatic circulation and combine with the repair tissue of the lens to form new polymers. A small amount of the polymer is excreted from the eye to the surface of the eye and eventually becomes eye stool. However, when the amount of polymer is large, its size will exceed the size of the drainage hole, and debris will accumulate in the lens, gradually forming a cataract.
Optometrists caution wearers not to wear contact lenses for long periods of time on the computer, which can lead to many serious consequences. Therefore, people who wear contact lenses and need to be exposed to computers for long periods of time must take them off during breaks to give their eyes sufficient time to expel waste, otherwise it will easily lead to cataracts over time.
