In the previous article, we discussed “Why are progressive eyeglass lenses so much more expensive than single vision lenses?”. In this article, let’s talk about “What high-end progressive lenses are the best, Zeiss or Essilor?”.
Essilor and Zeiss lenses are one of the world's four major lenses, both are the best in the field of optical lenses, and both have made indelible contributions to the field of optics.What high-end progressive lenses are better, Zeiss or Essilor?
Essilor Lenses
'Seeing the world better' is the goal that Essilor has always pursued, and 'people-oriented, winning with quality' is the basic point of Essilor's business philosophy. Essilor believes that the competition of talents is the foundation of all competitions. Only the personnel with professional ethics and professional ability can a company start from nothing and grow from small to large. The establishment of brand image and recognition by consumers can become a reality. Therefore, Essilor does not aim at a short-term profit, but focuses on the establishment of the company and brand, with long-term market share as the main goal. At the same time, they establish a good relationship with retailers and distributors, so that they can develop together for a long time, and pursue a real 'win-win'.
Essilor’s flagship brands include Varilux, Crizal, Airwear, etc. Varilux myopia lenses are mainly progressive lenses with super high refractive index and high-quality visual field, and the lenses are ultra-light and ultra-thin. Crizal lenses have excellent anti-fouling, abrasion resistance, anti-glare functions, and good light transmittance. Airwear lenses are PC lenses, and their chemical name is polycarbonate, which is a thermoplastic material. PC lenses are extremely tough and will not break (2cm can be used for bullet-proof glass), so they are also called safety lenses, which are currently the lightest materials used for lenses.
Zeiss lenses
Carl Zeiss AG is a German company that manufactures optical systems, industrial measuring instruments, and medical equipment. The name of the company comes from one of its founders, German optician Carl Zeiss (1816-1888). It was established in Jena in 1846 by Carl Zeiss, Ernst Abbe and Otto Schott.
Zeiss resin lens guarantees up to 99.4% of the lens light transmittance. The naked eye can no longer feel whether the lens is worn or not. So far, only Zeiss, the leading optical industry, can bring such extraordinary extreme effects. Moreover, in order to ensure the good imaging quality of the lens and make the lens longer life, Zeiss also adopted a new coating design, imported from Korea. The unique professional technology is combined with nanotechnology so that they manufacture the good quality of the top lens.
Which is better, Essilor lens or Zeiss lens?
1. Different high-density resin substrates. Essilor Diamond Crystal series 1.74 lenses use resin with a density of 1.46 as raw materials. The lens itself has higher hardness. Combined with Diamond Crystal series film layers, the lifespan of the lens is better improved. The outstanding abrasion resistance is obvious.
2. Different technical support. The greater the density of the lens, the harder the substrate. However, the larger the density of the lens under the same volume is heavier. Therefore, Zeiss has the best trade-off between density and component and selects high density on the basis of high refractive index and frivolity substrates.
3. Different Features. The anti-fog molecules on the two surfaces of the lens are activated by an anti-fog activator. Therefore, the fog differentiates into a thin layer that is invisible to the eyes, instead of forming a fog. Each spray of activator can last about a week. Zeiss resin lens guarantees up to 99.4% of the lens light transmittance, and the naked eye can no longer feel whether the lens is worn or not.
