Children's glasses
Children and adolescents are in the stage of growth and development, which is the peak period of eye use, and the degree changes very quickly.
Due to long-term close-range use of the eyes, the eyeballs will experience ciliary muscle spasms, and myopia will easily deepen.
Therefore, children and adolescents need to go to a professional eye hospital for reexamination every 3 months or half a year, and the glasses should be replaced in time if the degree increases by more than 50 degrees.
Adult glasses
Although the degree of myopia in adults has stabilized, there are also cases where the degree of myopia increases due to excessive use of the eyes, and the glasses will be worn out.
Therefore, medical optometry is also required for adults to wear glasses. Generally, glasses should be replaced once a year and a half to two years.
Glasses for the elderly
There is no uniform time limit for the specific replacement of reading glasses for the elderly. When the elderly wear glasses to read newspapers and feel tired, and their eyes are sore and uncomfortable, they should be replaced.
Do not be greedy for cheap and convenient for matching reading glasses! Wearing glasses at will will cause dizziness, headache, nausea and other discomforts. It is best for the elderly to have an optometry and a fundus check every one or two years.
