Glasses are equipped with the following components:
1. Accurate prescription. The data of optometry sheet includes myopia or hyperopia of the optician's left and right eyes and the pupil distance between the two eyes. If there is astigmatism, the astigmatism degree and axial position of astigmatism should be provided.
2. Be careful when choosing frames. The shape of the glasses frame is very important. Square or rectangular surfaces are suitable for elliptical or rectangular frames with certain radians. A round face is suitable for frames of any shape except round. Elliptical or oval faces are usually suitable for frames of any shape.
3. Thickness of spectacle lens. And the thickness of the lens is autocorrelation with the selected refractive index of the lens. At the same degree, the higher the refractive index, the thinner the lens. Generally, 1.56 refractive index can be selected within 300 degrees, 1.60 refractive index can be selected from 300 degrees to 500 degrees, 1.7 1 and 1.74 refractive index can be selected from 500 degrees to 800 degrees, and above 800 degrees can be selected.
