1.56 Semi Finished Single Vision Blue Cut Optical Lenses

Short Description:

Usually, there are six kinds of refractive index of resin lenses: 1.50, 1.56, 1.60, 1.67, 1.71 and 1.74. If you want a higher refractive index, you can only consider glass lenses, which have 1.80 and 1.90 to choose from. It’s just that glass lenses are used less often these days, although glass sheets also have lower refractive indices, such as 1.60 and 1.71.

Resin is a chemical substance with a phenolic structure. Resin lens is light weight, high temperature resistance, impact resistance is not easy to break, broken also has no edges and corners, safe, can effectively block ultraviolet rays, resin lens is also a favorite kind of eyeglasses for myopia people at present.

However, the wear resistance and chemical corrosion resistance of resin lens surface is worse than that of glass, the surface is easy to scratch, and the water absorption is larger than that of glass. These shortcomings can be improved by coating method.

Anti-blue light lens is a kind of digital protective lens that can effectively block high-energy harmful blue light, retain beneficial blue light, and reduce the damage of blue light to eyes. It is suitable for wearing when using LED digital display devices such as TV, computer, PAD and mobile phone.

Production Introduction

At present, there are two kinds of anti-blue light glasses:

First, the lens surface coating, through the film layer will be harmful blue light reflection, blue light has a barrier, so as to protect the eyes. These glasses refract blue light, so the lenses reflect the color.

Second, add anti-blue light factor in lens matrix, absorb harmful blue light in life, filter blue light, so as to protect eyes. The blue-blocking glasses absorb blue light, creating a yellowish color based on the principle of color complement.
