What Is Polycarbonate Lens?

Polycarbonate was invented in the 1970s for aerospace applications and is currently used for the helmet visors of astronauts and for space shuttle windshields.

What is the best lens material?

The world's first resin lens was made of CR-39 material, and CR-39 is still the main optical lens material in Europe and the United States.

How to protect your contact lenses?

When wearing contact lenses, do not drop any eye drops, and only use a special moistening solution for contact lenses. In daily life, we recommend that dry eyes can be relieved with lubricating fluid, but we do not advocate frequent use of lubricating fluid, so as not to make the eyes become dependent on lubricating fluid. The right way is to do blink training. The ingredients contained in the eye drops will remain in the lenses, which will cause certain damage to the eyes and pollute the lenses. Some eye drops can make the lenses tinted after use, which will affect the transmittance and a refractive number of the lenses and make the vision blurred. Ladies who need to make up should wear contact lenses before making up. When removing makeup, remove contact lenses before removing makeup, to avoid the makeup sticking to the lens and damaging the lens and eyes. Lenses should not be lent to others to avoid cross-infection of eye diseases. You can't wear contact lenses while swimming or bathing.

The frame must have enough vertical height, which can be selected according to the type of lens selected, otherwise, it is easy to cut off the near or far part when cutting the edge.Adjust the front angle of the frame based on the facial features of the wearer to match the frame with the face, which helps to maintain enough gradient field of vision.
