Myopia Glasses Should Be Accompanied Of Appropriate Degree
When choosing glasses, one should choose according to their own needs. Myopia or presbyopia, after optometry, should be accompanied by prescription glasses of appropriate degree, which can clearly see distant objects or make presbyopia clear from blurry to close-range objects.
Secondly, the nature of work is also a factor that affects the selection of glasses, mainly to protect the eyes from strong sunlight or certain radiation.
The function of lenses varies depending on the nature of their work.
(1) Purple, gray, or yellow lenses: can absorb some visible light and ultraviolet rays, suitable for use in sunlight.
(2) Blue, gray, or yellow lenses: capable of absorbing some visible light, suitable for observing furnace flames, melting enamel, glass, or melting steel ladle.
(3) Black and purple lenses: they can absorb most of the visible light and are mainly used by smelting workers, welding workers, and mountaineers.
(4) Flat lens: suitable for outdoor workers to wear and prevent the invasion of sandstorms.
If you notice a decrease in vision, you should go to the hospital for timely mydriasis and optometry. If diagnosed with true myopia, it is generally considered to wear glasses for correction, especially in teenagers and children. Because if you don't wear glasses at ordinary times, your eyes can't see clearly in the distance ahead, so it is easy for your eyes to use their regulating power, which will pay more attention to fatigue, which may lead to further progress. Wearing glasses can relieve Eye strain, so it's better to wear glasses for correction.
