Symptoms of glasses with high prescription

When fitting glasses, people have some deviations in their perception when measuring the degree, which results in the degree not being very accurate. If the prescription is too low, you will not be able to see clearly beyond a certain distance. If the prescription is too high, you will feel dizzy and your eyes will be swollen when you first put them on, and wearing them for a long time will cause your vision to deteriorate. Therefore, the degree of glasses must match, so what are the symptoms of glasses with too high a degree?

First, how to judge and what are the dangers of glasses with too high a degree.

A simple way to judge whether the degree of glasses is too high is to check the eye chart. If the corrected vision with glasses reaches above 1.0, it is too high. It is best to correct the vision to 0.8-1.0. If the correction is too high, the eyes will need to adapt to the glasses, which will inevitably cause damage to the eyes, such as dizziness, nausea and even unsteady walking. Although I was able to adapt to it after a long time, my dependence on glasses increased. For most myopic people, the degree of myopia is not very high when they first wear their first pair of glasses. However, the result of wearing glasses for a long time is that the degree of myopia increases every year until around the age of 20, when the eyeball development is completed and the degree change stops. It can be said that glasses are the culprit for worsening myopia. Therefore, from the perspective of protecting eyesight, the degree of glasses should not be too high. In addition, myopia means that you cannot see clearly at a distance, and glasses are used to correct this, so try not to wear them when seeing close up.

Second, don’t blindly pursue high-degree glasses.

The principle of correcting myopia is to better have less than too much, and the visual acuity should be 1.0. Don’t blindly pursue students’ corrected visual acuity of 1.2 when wearing glasses, some even pursue 1.5. Glasses with too high a degree can easily cause myopia to worsen too quickly.

Third, pay attention to the process of fitting glasses.

It is recommended that those who need to wear glasses should go to a specialized ophthalmology hospital or a regular glasses dealer for a reasonable examination and eye test, and then wear glasses based on the results of their own examination. Whether it is ordinary or contact lenses for myopia, you must undergo a correct eye examination before you can wear glasses. Otherwise it will have a counterproductive effect.
