the reasons for the deepening of eye degree
there are two reasons for the deepening of myopia, one is pathological myopia, the other is not paying attention to eye hygiene and incorrect eye habits.
pathological myopia is a disease within the eye, which is hereditary. It shows that myopia continues to deepen and increases rapidly. If the degree of myopia increases by more than 100 degrees or even more than 200 degrees within a year, or it reaches 2000 degrees in total. Excessive eye use is usually manifested in that if the lighting is too bright or too dark, the eye use time is too long, and eye diseases such as trichiasis, ptosis and keratitis are not diagnosed and treated in time, it will aggravate myopia. This reason is more common. How often do
glasses change?
many people wear glasses until they are broken or can’t be used. This is actually wrong. Ordinary myopia patients should generally change their glasses once every two years, one is to adjust the degree, the other is & ldquo; Update & rdquo;. Once there are scratches on the glasses mirror, it will obviously affect its optical correction performance. Therefore, the glasses should be maintained and inspected regularly and updated in time to keep them in good working condition.
teenagers with particularly rapid changes in degrees had better change their glasses once a year or half a year. Teenagers are at the peak of eye use. Due to long-term close eye use, there will be ciliary muscle regulation spasm, and myopia is particularly easy to deepen. Teenagers who use their eyes excessively should have optometry once every six months (mydriatic Optometry). If the glasses are not suitable for the change of diopter of myopia, they should change them in time.
How to clean glasses
take a little hand sanitizer or shower gel and apply it on the glasses to start decontamination. Wet with water first, preferably flowing water. After applying the washing solution, gently wash the eye lenses and spectacle frames with your fingers. After a short period of time, after the foam is removed, the foam is washed away with the flowing water. After washing, be careful not to wipe it with glasses cloth. It can be dried naturally. If you are in a hurry to wear it, you can wipe it gently with a face paper towel. Do not use glasses cloth, because there is too much water, or simply wash the glasses cloth.
