First, measure the focal length, eye muscles, strabismus and other items (children need to do mydriasis) with the instrument, as well as the color blindness test and the Amsler square table test which can detect the macular lesions. After a complete optometry test, the next step is to select high quality optical glasses that meet personal conditions.

Glass lens is the most common type of lens in the past, which is scratch resistant and not easy to wear. Its disadvantage is that it is heavy and easy to break, which is not suitable for children or sports.

 

 

(2) Resin Lens

 

The main characteristic of resin lens, also known as safety lens, is its light weight and impact resistance. Therefore, it gradually replaces glass lens as the main lens material. However, its disadvantage is that the surface is easy to scratch, so it is often necessary to add wear-resistant layer to increase its hardness to improve the problem.

If the stability of the frame is poor, which is easy to cause the lens loose, so it needs to be adjusted regularly. The choice of high quality optical frames must match the pupil distance. The best choice is small frame for high myopia.
