Can astigmatism cause iridescence

summary

I was originally short-sighted, and the degree is still very high. Recently, I've been a little over using my eyes. I always feel that my eyes are very tired and blurred. Sometimes I can't see clearly. I go to see a doctor, and the doctor says it's astigmatism. Now let's talk about whether astigmatism can cause iridescence.

Can astigmatism cause iridescence

First, astigmatism does not cause iridescence. Generally speaking, iridescence is a kind of visual phenomenon, which mainly occurs when corneal edema is caused by elevated intraocular pressure, when secretion is attached to the surface of conjunctivitis cornea, when the anterior surface of cornea is covered with tears, when there is water vapor on the surface of glasses, when patients with early cataract and when multifocal intraocular lens is implanted after individual cataract surgery.

Second: the correct use of eyes, reading to maintain a certain distance, after a period of time to look at a long distance, relieve eye fatigue. Do eye exercises regularly. Don't often sit in front of the computer, often go out for a walk, do exercise and yoga can help your eyesight, and do eye movement before going to bed at night.

Third: astigmatism is that the parallel light entering the eyeball can not form a focus on the retina, but form a focal line, so far and near objects can not form a clear image on the retina, and can only be corrected by wearing appropriate astigmatism lenses.

matters needing attention

Astigmatism is not a serious disease, but we all know the importance of eyes to us. Therefore, the harm of astigmatism to us can not be ignored. We must treat it as soon as possible, and pay attention to the maintenance of eyes at the same time.
