Selection of spectacle lenses

The choice of spectacle lenses should be based on the condition of your own eyes and the diopter. First of all, look at the lens material of glasses. Now there are three main materials for glasses lenses, glass, resin and PC lens.

The advantages of glass sheets are good light transmittance, not easy to yellow, and cheap price. Among all the same materials, lenses of the same power are the thinnest. However, one of the biggest disadvantages is that it is easy to Broken, it is very unsuitable for children to wear glass lenses, as it is easy to produce fragments and hurt the eyes. This kind of lenses has gradually disappeared from the market.

The light transmittance of resin lenses is good, the yellowing rate is in the middle, and various films can be coated on the surface. One disadvantage is that resin lenses are thicker than PC lenses and myopia lenses of the same power. For high-end glasses, It is not recommended to choose resin for the film, because the resin will appear extremely thick.

PC film is also called cosmic film. It has good light transmittance, low yellowing rate and high refractive index. The biggest advantage is that it is not easy to break into fragments and stick to the eyes after being injured. The US FDA has a rigid regulation of 18 Children under the age of 18 can only wear PC lenses for spectacles. However, PC lenses have a disadvantage, which is that they are relatively soft and easy to wear.
