Production Introduction
How to control the thickness and weight of the lens?
The thickness of the lens is related to the height of diopter, refractive index of the lens and the shape and size of the frame, so when choosing the thickness of the lens, you should refer to your myopia degree. If the degree is higher, choose high refractive index lens preferentially, so the lens thickness is relatively thin, can also greatly reduce the pressure on the bridge of the nose.
Furthermore is the weight of the lens, when it comes to the weight, certainly not related to the material of the lens, the lens material on the market is generally glass, resin and PC, glass lens is the heaviest, PC lens is the lightest, so in the choice, the thickness and weight of the lens should also be taken into account.
