(Summary description)Short-wave blue light is light with relatively high energy wavelengths between 400nm-480nm. Blue light in this wavelength will increase the amount of toxins in the macular area of ​​the eye, which seriously threatens the health of our eyes. Blue light exists in a large amount in computer monitors, fluorescent lamps, mobile phones, digital products, display screens, LEDs, etc. The blue light in this wavelength will increase the amount of toxins in the macular area of ​​the eyes, which seriously threatens our eye health.

Let's first briefly understand what is blue light?

Short-wave blue light is light with relatively high energy wavelengths between 400nm-480nm. Blue light in this wavelength will increase the amount of toxins in the macular area of ​​the eye, which seriously threatens the health of our eyes. Blue light exists in a large amount in computer monitors, fluorescent lamps, mobile phones, digital products, display screens, LEDs, etc. The blue light in this wavelength will increase the amount of toxins in the macular area of ​​the eyes, which seriously threatens our eye health.

Blue light can be seen everywhere in daily life, but the main source of harmful blue light is the LED LCD screen. Today's LCD screens are all LED-backlit. Since the backlight requires the effect of white light, the industry uses blue LEDs mixed with yellow phosphors to form white light. Since the blue LED is a main piece of hardware, the blue spectrum in this white light has a peak, which causes what we call the problem of harmful blue light.

The blue light in the 415nm-455nm band, because of its strong energy, can penetrate the lens of the eye and reach the macular area, which may cause macular degeneration.

Anti-blue light lenses are mainly used to block the damage of high-energy harmful blue light to the eyes, and are mainly used by people who face LED digital displays such as computers, PADs, and mobile phones for a long time.

There are three main types of anti-blue light technology:

1. Coating reflection technology: The blue light is reflected by the coating on the surface of the lens, so as to achieve the blue light blocking effect.

2. Substrate absorption technology: The anti-blue light factor is added to the lens material 2113 itself to absorb blue light, so as to achieve the blue light blocking effect.

3. Film layer reflection + substrate absorption: This is the latest anti-blue light technology, which combines the advantages of the above two technologies, and double means double-effect protection. This technology is currently used in bright moon lenses.

However, if you are a student and often read with your eyes, it is not recommended to use anti-blue light glasses. Because the anti-blue light glasses block blue light, the 4102 picture you see will be yellowish and dark; if you wear anti-blue light glasses to read , actually not good.

The key is to rely on you to develop a good eye habit, pay attention to eye rest, and eat some foods that are similar to carrots with eye-enhancing effects. Of course, in terms of glasses, you can consider glasses made of lenses with relatively high transmittance such as PMC super bright lenses. With high light transmittance, things will look bright and clear, which is helpful for reading books.
