1.74 Blue Coat HMC Optical lenses

Short Description:

Eyeglass 1.74 means the lens with refractive index of 1.74, which is the one with the highest refractive index on the market, and the one with the thinnest lens thickness. Other parameters being equal, the higher the refractive index, the thinner the lens, and the more expensive it will be. If the degree of myopia is more than 800 degrees, it is considered to be ultra-high myopia, and a refractive index of 1.74 is suitable.

Anti-blue light glasses can effectively reduce the continuous damage of blue light to the eyes. Through the comparison and detection of portable spectrum analyzer, the use of anti-blue light glasses can effectively suppress the blue light intensity emitted by the mobile phone screen, and reduce the damage of harmful blue light to the eyes.

Anti-blue light glasses mainly through the lens surface coating will be harmful blue light reflection, or through the lens substrate added anti-blue light factor, harmful blue light absorption, so as to achieve the harmful blue light barrier, protect the eyes.

Production Introduction

1. good lens, material is the key

The material of a pair of lenses plays a decisive role in their transmittance, durability and Abbe number (the rainbow pattern on the surface of the lens). It can carry out in-depth research and development on materials, with controllable quality and excellent performance.

2. film layer, make the lens easy to wear

Good lens film layer can give the lens more excellent performance, not only the optical performance such as transmittance has been greatly improved, its hardness, wear resistance, durability will be greatly improved.

3. practical function, suitable for eye scene

Suitable is the best, different occasions need corresponding to the purchase of different practical functions of the lens. For example, people with high frequency of computer use can focus on blue-blocking lenses; People who frequently go outdoors and indoors can consider smart color changing lenses; Drivers can consider driving polarized lenses; People who exercise regularly should consider super tough lenses...

4. Visual effect, comfortable to wear

The lenses on the market usually include spherical, aspherical, two-sided aspherical, single-light or multi-focus visual design. Good visual design can enhance the visual reality, relieve visual fatigue, and improve consumers' wearing experience.
