Why are some glasses expensive and others cheap?

Lenses do not regulate vision, but some progressive lenses can help the ciliary muscles to adjust. The quality of the lens is mainly determined by the transmittance, the surface, the aspherical surface, the refractive index, the coating quality.

The higher the refractive index, the thinner the lens, and the more expensive the price, for some people with high degrees, the lenses also play an aesthetic role. Commonly used are green film, and some are purple film, gold film, etc. How much cheaper is a relative number, and there are many other factors to consider besides price.



The Disadvantages of Aspheric Lenses

Here, we will show some disadvantages of aspheric lenses.

The aspheric lens has a relatively small light area. When the eyeball rotates around, it will blur a little when looking at the outside through lens edge. In other words, the visual range of the line of sight becomes smaller.

Human’s eyeball is spherical and the eyeball rotates to the edge. Through aspheric lenses, the objects near the eye appear protruding.


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.

If you wear this kind of glasses, you are the most handsome boy in the whole street. Of course, black-rimmed glasses have their benefits. Many big-name fashion magazines often use them to give stars a concave look during the shoot.


Different Types of Progressive Lenses

Premium progressive lenses are designed to provide a wider and smoother view. These lenses are highly customizable for your prescription, chosen frame and eye anatomy.

Premium progressive lenses can incorporate your dominant eye into the design and make transitioning between different prescriptions feel smoother as well. However, due to these features, premium progressive lenses are more expensive than traditional lenses.
