Essilor lenses have become the world's high-end brand lenses, and the research on lenses has made continuous progress, which has made a great impact on the progress of lenses. Essilor lenses are also one of the lenses that people are full of praise today. Let's take a look at the Essilor lens series. Essilor Lens Series Diamond Crystal Series E-SPF (Lens Sun Protection Factor) was first adopted by Essilor, becoming the latest global standard for lens protection against UV. Ordinary Essilor (refractive index 1.5), diamond crystal UV, E-SPFu003d10; diamond crystal A2, E-SPFu003d5; diamond crystal Zhijie, E-SPFu003d5 diamond crystal UV not only can effectively block the front surface injection The ultraviolet rays of the lens can also block the ultraviolet rays reflected from the back surface of the lens, and comprehensively protect the eyes. It has the effects of reducing reflection, waterproofing, abrasion resistance, stain resistance, dust resistance, double-sided protection, and blocking ultraviolet rays. Diamond Crystal A2 has the functions of reducing reflection, waterproofing, abrasion resistance, stain resistance and dust resistance. Zhuanjing Zhijie has the effect of reducing reflection, waterproofing, abrasion resistance and stain resistance. Through the use of unique and innovative technology, the Optifog anti-fog lens has a good visual effect. It quickly spreads out evenly and becomes an ultra-thin water film. The anti-fog lens coated with Essilor Anti-Fog Cleaner has a super anti-fog effect and lasts for one week. When using it, put a drop of Essilor anti-fog cleaner on both sides of the anti-fog lens, and then gently wipe the surface of the lens with the fiber cloth in the cleaner package. The entire cleaner is not full on the lens, and then lighten it. Until it is wiped clean. Essilor cosmic lens is extremely light, even lighter than ordinary resin lens. The lens is very thin, thinner and flatter than ordinary resin lenses. It has strong impact resistance. The Essilor Universe lens is made of the same material as the windshield of the safety helmet, which can withstand stronger impact. Good abrasion resistance, brand-new craftsmanship, the lens has super abrasion resistance, and the lens life is longer. Effectively resist ultraviolet rays, UVA and UVB, and protect eyes. Essilor Anti-Fatigue Lens The Essilor anti-fatigue lens produced by the research on the 'microwave' of the eye can restore the 'microwave' of the eye to normal and combat visual fatigue.
