summary

In the past, we knew that glasses only had myopia and hyperopia, but now there will be astigmatism. This is different from hyperopia. Let's share the reasons for astigmatism.

How is eye astigmatism to return a responsibility

Reason 1: the symptoms of visual fatigue are usually related to age and the nature of work. The older the person is, the more moderate astigmatism will be caused by sitting at a desk. If it is lower than the normal value, we need to treat it as soon as possible and as soon as possible.

The second reason is the change of astigmatism during close-up. When both eyes look inward and downward, the eyeball rotates at the same time, which changes the astigmatism axis of the eye. Therefore, the appropriate far and near lenses can be selected according to the patient's different age, focus depth and relative adjustment force.

The third reason is the influence of spectacle lens, which is caused by the uneven effect of image size, the movement of axial position, and the inequality of lens surface. Sometimes the size of lens frame may also affect the peripheral optical problems and cause astigmatism. This is not the reason for personal eyes, it belongs to the optician.

matters needing attention

People with astigmatism should pay attention to the frequency of using their eyes in life. At night, they should not lie in bed and play with their mobile phones, and they should not play with their mobile phones sideways. At ordinary times, they should move their eyes more, do not play with computers for a long time, and learn to relax themselves.
