1.56 Bifocal Flat Top Photochromic Gray HMC Optical lenses
With the demands of modern life, the role of color-changing glasses is not only to protect the eyes, it is also a work of art. A pair of high-quality color-changing glasses, with appropriate clothing, can foil a person’s extraordinary temperament. Color-changing glasses can change according to the intensity of ultraviolet light and make its color change, the original transparent colorless lens, encounter strong light irradiation, will become colored lenses, to do protection, so suitable for indoor and outdoor use at the same time.

1.59 Photochromic Gray HMC Optical lenses
PC, chemically known as polycarbonate, is an environmentally friendly engineering plastic. PC material features: light weight, high impact strength, high hardness, high refraction index, good mechanical properties, good thermoplasticity, good electrical insulation performance, no pollution to the environment and other advantages. PC is widely used in Cdvcddvd disc, auto parts, lighting fixtures and equipment, glass Windows in the transportation industry, electronic appliances, medical care, optical communication, eyeglass lens manufacturing and many other industries.

1.74 Spin Photochromic Gray HMC Optical lenses
The advantage of the color-changing lens is that in the outdoor sunlight environment, the lens is gradually turned from colorless to gray, and after returning to the room from the ultraviolet environment and gradually return to colorless, it solves the trouble of wearing sunglasses for myopia, and achieves a pair of indoor and outdoor.

1.71 Spin Photochromic Gray HMC Optical lenses
Intelligent color changing lens changes with the intensity of ultraviolet light, automatically adjust the color depth, one mirror is multi-purpose, no switching trouble, indoor and outdoor more convenient, more eye protection.
Intelligent color change factor shows shear structure distribution, when exposed to ultraviolet irradiation, the molecule automatically closes to block the light entry, using its good photoresponsiveness and coloring, rapid response to light changes, more efficient.

1.67 Spin Photochromic Gray HMC Optical lenses
Color-changing lenses, also known as “photosensitive lenses”. According to the principle of photochromatic tautometry reversible reaction, the lens can darken rapidly under light and ultraviolet irradiation, block strong light and absorb ultraviolet light, and show neutral absorption of visible light. Back to the dark, can quickly restore colorless transparent state, ensure the lens transmittance. Therefore, color-changing lenses are suitable for indoor and outdoor use at the same time to prevent the damage of sunlight, ultraviolet light and glare to the eyes.

1.61 Spin Photochromic Gray HMC Optical lenses
Spin coating change Lens : Spin coating change Lens change adopts spin change technology, which completely subverts the previous basic change technology. Compared with base transformation, it is uniform and has no background color; Compared with the traditional film changing method, it is superior to the soaking method. The color changing liquid and the hardening liquid are placed in different processes, which not only ensures the adhesion of the color changing liquid, fully maintains its color changing tension, but also exerts the hardening fixation effect and strengthens the hardness. With double-layer spin coating technology and hardening protection, the process quality is greatly improved. Advantages: rapid and uniform color change. It is not limited by the material, and any ordinary aspheric surface, 1.56, 1.61, 1.67, 1.74, etc. can be processed into a film-changing lens. There are more varieties, and consumers have more choices.

1.56 Photo Colorful HMC Optical lenses
Photochromic lenses, also known as “photosensitive lenses”. According to the principle of light-color interconversion reversible reaction, the lens can quickly darken under the irradiation of light and ultraviolet rays, block strong light and absorb ultraviolet rays, and absorb visible light neutrally; when it returns to the dark place, it can quickly restore the colorless and transparent state, ensuring the lens of transmittance. Therefore, photochromic lenses are suitable for both indoor and outdoor use to prevent damage to the eyes from sunlight, ultraviolet light and glare.

1.56 FSV Photo Gray HMC Optical lenses
Photochromic lenses not only correct vision, but also resist most of the damage to the eyes from UV rays. Many eye diseases, such as age-related macular degeneration, pterygium, senile cataract and other eye diseases are directly related to ultraviolet radiation, so photochromic lenses can protect the eyes to a certain extent.
Photochromic lenses can adjust the light transmittance through the discoloration of the lens, so that the human eye can adapt to the change of the ambient light, reduce visual fatigue and protect the eyes.

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 as the good news for people with myopia + presbyopia, which dispenses with the trouble of frequent picking and wearing.
Bifocal lens piece removed the trouble of myopia and presbycusis frequent pick and wear, see far and near can see clearly, the price is also cheaper.
-
1.56 Progressive Blue Cut HMC Optical lenses
A Progressive lens is a multi-focal lens. Unlike traditional reading glasses and double-focal reading glasses, progressive lenses don’t have the fatigue of having to constantly adjust the focus of the eye when using double-focal lenses, nor do they have a clear dividing line between the two focal lengths. Wear comfortable, beautiful appearance, gradually become the best choice of presbyopia crowd.

1.59 PC Bifocal Invisible Blue Cut HMC Optical lenses
Bifocal lenses or bifocal lenses are lenses that contain two correction areas at the same time and are mainly used to correct presbyopia. The far area corrected by the bifocal lens is called the far area, and the near area is called the near area and the reading area. Usually, the distal region is large, so it is also called the main film, and the proximal region is small, so it is called the sub-film.

1.59 PC Progressive Blue Cut HMC Optical lenses
PC lens general resin lenses are hot solid material, that is, the raw material is liquid, heated to form solid lenses. PC film is also known as “space film”, “space film”, the chemical name of polycarbonate, is a thermoplastic material.
PC lens has a strong toughness, not broken (2cm can be used for bulletproof glass), so it is also called safety lens. The specific gravity per cubic centimeter PC lens is only 2 grams, which is the lightest material used for lenses at present. PC lens manufacturer is the world’s leading Esilu, its advantages are reflected in the lens aspheric treatment and hardening treatment.
