1.70 Glass White UC Optical Lens
The main raw material of glass lens is optical glass. The transmittance and mechanical and chemical properties of glass lens are relatively good, with constant refractive index and stable physical and chemical properties. Therefore, the glass lens is thinner than the resin lens at the same deg...
1.523 Glass Progressive Optical Lens
The main raw material of glass lens is optical glass. The transmittance and mechanical and chemical properties of glass lens are relatively good, with constant refractive index and stable physical and chemical properties. Progressive lenses are developed on the basis of bifocal lenses. The use...
1.523 Glass Mineral Single Vision White UC Optical Lens
The main raw material of glass lens is optical glass. The transmittance and mechanical and chemical properties of glass lens are relatively good, with constant refractive index and stable physical and chemical properties. The glass sheet has excellent optical properties, is not easy to scratch...
1.56 Semi Finished Bifocal Photochromic Photogrey Optical Lens
When a person’s eye adjustment is weakened due to age, he/she needs to correct his/her vision separately for the far and near vision. At this time, he/she often needs to wear two pairs of glasses separately, which is very inconvenient. Therefore, it is necessary to grind two dif...
1.56 HMC Single Vision Optical Lens
Lenses with 1.56 index are considered the most cost effective lens on the market. They possess 100% UV protection and are 22% thinner than CR39 lenses.These lenses with knife edge finishing suit those irregular frame sizes (small or large) and make any pair of glasses look much thinn...
1.70 Glass White UC Optical Lens
The main raw material of glass lens is optical glass. The transmittance and mechanical and chemical properties of glass lens are relatively good, with constant refractive index and stable physical and chemical properties.Therefore, the glass lens is thinner than the resin lens at the ...
1.56 Semi Finished photo grey Optical Lenses
The glass lens of the color-changing lens contains a certain amount of silver chloride, sensitizer and copper. Under the condition of short wave light, it can be decomposed into silver atoms and chlorine atoms. Chlorine atoms are colorless and silver atoms are colored. The concentration of silver...
1.59 Blue Cut PC Progressive Photochromic Gray HMC Optical lenses
The so-called functional lens refers to special glasses that can bring certain favorable characteristics to the eyes of specific people in specific environments and stages, and can change the visual feeling and make the line of sight more comfortable, clear and soft.Color-changing lenses: the pur...
1.59 PC Bifocal Invisible Photochromic Gray HMC Optical lenses
At present, there are two kinds of lens materials on the market, one is glass material, the other is resin material. Resin materials are divided into CR-39 and polycarbonate (PC material).Bifocal lenses or bifocal lenses are lenses that contain two correction areas at the same time and are mainly...
1.56 Bifocal Blue Cut HMC Optical lenses
As the name suggests, a bifocal mirror has two luminosity. Generally, it is used to see the distance, such as driving and walking; The following is to see the near luminosity, to see the near, such as reading, playing mobile phone and so on. When bifocal lens just came out, it was really regarded...
1.71 Single Vision HMC Optical lenses
1.71 lens Full name 1.71 refractive index lens, with high refractive index, high transmittance, high Abbe number characteristics, in the case of the same myopia degree, can significantly reduce the thickness of the lens, reduce the quality of the lens, at the same time, make the lens more pure an...
RX 1.499/1.56//1.60/1.67/1.74 single vision/progressive/blue cut/round-top/flat-top bifocal/photochromic lens
Lens surfaced according to prescriptions in the lens laboratory is called Rx lens. In theory, it can be accurate to 1°. At present, most of Rx lens is ordered by a gradient power degree of 25. Of course, parameters such as pupil distance, asphericity, astigmatism and axial position are customized...
