Today's contact lenses are becoming more and more light and thin, and they are also more fragile. Even if the wearer takes care of them carefully, they may still encounter damage. Sometimes, the contact lens only has a small crack at the edge, and it does not seem to have a large gap or breakage. Can it still be worn?
Although the contact lens is only a bit cracked, it is also damaged, and its surface is no longer regular and smooth. It is likely to cause a strong foreign body sensation and red blood streak if you continue to wear it. The corneal tissue may be damaged during the rubbing of the cornea. In general, a small gap may not affect the visual effect, but if the lens breaks in the eye, it will not be worth the loss, so it can never be worn.
It is observed that most lenses are most prone to breakage at the edges, and there are many reasons for the breakage of the lens. It may be that the lens dries and hardens after being dehydrated for a long time, which may cause chipping when it is taken, or it may be a scratch caused by too long nails or too sharp tweezers. In addition, if the contact lens is stored, the lens floats on the care solution or the care solution is poured too much, which will cause the lens to be screwed into the cover and cause damage.
In short, no matter whether the contact lens is cracked or cracked, it can't be worn anymore. You must immediately replace a new pair of lenses or wear frame glasses. If the problem of lens fragmentation often occurs, in addition to the quality of the lens, it may also be caused by improper operation and wearing. You should pay attention to whether the steps of taking and cleaning the lens are correct.
