Description

Do benefit to blue light lens of preventing that improves visual clarity

Technical Field

The utility model relates to an eyeglass especially indicates a do benefit to improvement vision definition prevent blue light lens.

Background

Along with the popularization of electronic products, the time for people to watch a screen is longer and longer, and the blue light in screen luminescence can cause harm to human eyes after being irradiated for a long time due to strong penetrability of the blue light. Therefore, many blue light prevention glasses are put on the market, but most glasses aim at people with abnormal eyesight (myopia and presbyopia), and the blue light prevention function is added into common glasses. However, when people with normal vision wear ordinary flat blue-light-proof glasses, even the flat glasses can feel fatigue due to the reduction of definition because the flat glasses are not worn in daily life, and the protection of eyes becomes quite adverse.
