How to add astigmatism to myopia lenses

Everyone knows that when fitting glasses, doctors will choose different types of glasses based on the patient's eye degree. However, most myopic patients not only have myopia, but also astigmatism. If a person has astigmatism, he or she should add an astigmatism function to the eyes when wearing glasses. Therefore, many myopic patients are wondering how to add astigmatism to myopia lenses?

Astigmatism is different from myopia. If the astigmatism is above 75 degrees, you need to wear astigmatism lenses to correct your vision. To make astigmatism glasses, a cylindrical lens is ground into a certain spherical lens, and then a cylindrical lens is ground on the concave surface of the spherical lens. The spherical lens is the myopic part, and the cylindrical lens is the astigmatism part. Together they form myopic spherical lens + myopic astigmatism.

Nowadays, when many people with astigmatism get glasses, the usual practice is to subtract half of the astigmatism degree and add it to the myopia degree. In fact, the problem of astigmatism has not been solved, it has only deepened the degree of myopia. It may cause worsening of myopia and aggravate eye discomfort symptoms; vision may be corrected but astigmatism may still exist; symptoms such as headache and eye fatigue may occur.

The best way to avoid wearing glasses for myopia and astigmatism is to reduce the degree of myopia and astigmatism and improve vision.

Developing reasonable eye habits is the first step

It is recommended that children pay attention to eye hygiene and avoid looking at things for long periods of time in strong or dim light; prevent video terminal-induced eye fatigue (such as dry eyes, dizziness, and other video terminal syndromes).

When reading, the distance between eyes and book should be 30 cm, posture should be correct, do not read while lying down or reading while walking, and there should be sufficient light. After reading, writing, watching TV or using the computer for 40 consecutive minutes, you should close your eyes and look into the distance for 5 minutes. Go to the hospital for a checkup every 3 months or 6 months; pay attention to eating habits and nutritional combinations to avoid deficiencies in trace elements such as chromium and calcium.

Taking medication in time is the second step

Doctors generally recommend taking Lejing Vision Nutrients with warm water. If you take it for a period of time, it can quickly reduce the degree of myopia and astigmatism and improve vision. The younger you are, the easier it is to recover.

Whether glasses are needed must be accurately tested

It is generally recommended to wear glasses for correction of myopia and astigmatism when it affects vision. Parents should not blindly wear glasses for their children.
