how to choose a pair of glasses that suits you?

Optometry

Accurate optometry is the key prerequisite for proper glasses. Please select a qualified institution or a hospital optometry Center for optometry.

Two. Lenses

Material: generally recommended resin film, ultra-high myopia, glass film.

Refractive index: the higher the refractive index, the thinner the lens. Therefore, according to different degrees, the selection is different:

< 200 & deg;, 1.50 or 1.56;

200°-400°,1.60;

400 & deg; to 800 & deg;, 1.67;

800 & deg; or above, 1.74 or glass lens.

Shape: low degree, you like it; medium height, recommend aspheric lens;

Three. Spectacle frame

Five requirements: light weight, not easy to deform, good processing quality, appropriate size, try to wear it after selection.

It is not recommended to choose glasses with large frame (although it can increase the color value, it has certain influence on the eyes).

Warm tip: the degree of small points (for example, it is clearly 700 & deg; and 550 & deg; is required) does not reduce the degree. It is recommended to match it to 1.0-1.2. Unless, like Xiaobian, you need to face the computer for a long time every day or use it for close use, and you can match it to 0.8.
