Why Do Modern People Urgently Need Blue Light Glasses?

Nowadays, we always keep our hands on smart phones and tablet computers. Most of these 3C products with touch function use blue light technology. The screen is brightly colored and the color brightness is quite high, and the damage to eyesight cannot be underestimated. Indeed, since the advent of tablet computers such as the iPad, the convenience of audio-visual, gaming, and reading has made entertainment available anytime, anywhere, and everywhere. Therefore, more and more people are deeply fascinated by it and unable to extricate themselves. However, while these 3C products provide convenience, they also change many people's eye habits, posing a serious threat to their vision health.

As a result of the increasing popularity of 3C products, many people  have problems with their vision health. For example, many young and middle-aged people in their 30s and 40s have used their eyes too much and failed to protect themselves from harmful light, which led to early reporting of cataracts. In view of this situation, anti blue light glasses came into being.

Who Should Use Anti-blue Glasses?

Anti blue light eyeglasses are suitable for wearing when using LED digital display devices such as TVs, computers, PADs and mobile phones, but it is not recommended to wear anti-blue light glasses for a long time in daily life. Because anti-blue glasses filter some blue light, the picture will be yellowish when looking at objects. It is recommended to wear two pairs of glasses, one pair of ordinary glasses for daily use, and one pair of anti-reflective blue light glasses when using LED display digital products such as computers. Flat light (no degree) anti-blue light glasses are very popular among non-myopia users. They are used exclusively for computer work and gradually become a fashion.

The Role of Anti-blue Glasses

Anti blue glare glasses can effectively reduce the continuous damage of blue light to the eyes. Through the comparative test of the portable spectrum analyzer, after using the anti-blue glasses, the intensity of blue light emitted by the mobile phone screen is effectively suppressed, reducing the harmful blue light to the eyes.

Anti-blue glasses mainly reflect harmful blue light through the surface coating of the lens, or add anti-blue light factors through the lens substrate to absorb harmful blue light, thereby achieving the blocking of harmful blue light and protecting the eyes.

Any anti blue ray lens that uses film reflection technology, because it reflects harmful blue light, the surface of the lens will reflect blue light. The blue light blocking prescription lenses with substrate absorption technology will not reflect blue light.

Advantages And Disadvantages of Anti-blue Glasses

Anti-blue glasses are glasses that can prevent blue light from irritating the eyes. Special anti blue light blocking glasses can effectively isolate ultraviolet rays and radiation and can filter blue light. These glasses are suitable for use when watching a computer or TV.

The advantage is to increase light transmittance, filter unnecessary ultraviolet and infrared light, and prevent dispersion. The disadvantage is that the inner surface of the anti-blue lens reflects blue light, and if the light source is behind it, it will hit the eyes.

Blue light reading glasses are suitable for old people to read newspapers, and blue light glasses for children are suitable for young kids to study and read.
