Blue Control Lens
Modern lenses generally have UV400 level anti-ultraviolet function, which can effectively block harmful ultraviolet rays. Therefore, few people who wear glasses have eye diseases related to ultraviolet rays, such as cataracts.
After the launch of Apple iPhone and iPad to the market, electronic products such as mobile phones or tablet computers became indispensable equipment in our lives, and were used day and night for a long time. However, the LED screens of these electronic products emit high-energy blue light. Prolonged use of electronic products can cause dry eyes, tired eyes and affect sleep quality (ie Digital Eye Strain). Especially in a low-light environment, the pupils will dilate, the blue light will be received more, and the symptoms of discomfort will appear faster.
According to the principle of light-emitting technology, the blue light wavelength of the LED screen emits extremely high energy. (If you are interested, you can study LED by yourself)
Anti-Blue lens (Blue Control / Blue Cut lens) reflects the highest energy blue light (accounting for about 20% of the blue light band), which can effectively reduce the impact of the LED screen on the eyes. It helps in reducing eye dryness, eye fatigue, and allowing a longer period of comfortable use electronic products.
Blue light is one of the three primary colors, completely reflecting blue light is equivalent to color blindness. The general practice is to reflect 20% of the highest energy blue light. There are anti-blue mirrors that reflect 40% of blue light on the market. This kind of mirror has very obvious chromatic aberration. (We only sell lenses that block 20% of Blue light.)
