Spectacle lens is a kind of optical glass, which can make your field of vision wider and clearer with light transmission, and can effectively block the astigmatism of ultraviolet and infrared rays. For myopia patients, wearing moderate optical glasses can also effectively correct the refractive index, help you delay the development of vision, and improve the vision of your eyes. So what are the materials for spectacle lenses, and which is the best material for spectacle lenses?

1.The materials of spectacle lenses can generally be roughly divided into four types: glass lenses, resin lenses, space lenses (also called PC lenses or universe lenses), special lenses, etc.

Generally speaking, the materials of spectacle lenses can be roughly divided into four types: glass lenses, resin lenses, space lenses (also called PC lenses or cosmic lenses), special lenses, etc., no matter what kind of material the spectacle lenses have their own Features and disadvantages. For example, for glass lenses, its biggest characteristics are high hardness, high refractive index, high light transmittance and scratch resistance. However, compared with lenses of other materials, the weight is relatively heavy, and long-term wearing will cause eye discomfort. So for young myopia patients, it is best not to choose glass lenses, you can choose natural resin lenses.

Cyxus blue light blocking glasses adopted PC lenses which are a smart choice for athletes, those who work in hazardous job environments, and especially for children.

2.the use of glass and resin lenses is more common

According to the analysis of the current spectacles industry, glass and resin lenses are widely used, especially resin lenses, which are a mixture of multiple polymer compounds with different melting points and heat resistance. They are used for manufacturing. The resulting spectacle lenses have super high light transmittance and refractive index, and have the ability to filter out ultraviolet rays and glare 100%. They are currently the most trusted lens material for mankind. The biggest advantage of the space lens is that it has super toughness, super impact resistance, high corrosion resistance, and can effectively avoid eye damage due to violent sports lens rupture. It is currently a relatively high safety glasses. The sheet material is more suitable for the production of sports glasses.
