Why we need blue light blocking glasses?
The world is filled with artificial blue light from electronics such as TVs, phones, tablets and computers. Scientists find that exposure to artificial light in the evening and long hours of screen time ruins your sleep and causes sore eyes and headaches. Bad sleep leads to depression, weight gain, lower sex drive, and increased risk of heart disease.

There is a SOLUTION!
OurBlue light blocking glasses will super charge your sleep and health by blocking harmful blue light from electronic devices while letting in all other safe light. Wearing the computer glasses at least an hour before bedtime leaves you free to watch TV and use devices without ruining your sleep. Wear when working on computers or gaming to stop sore eyes and headaches.
Blue blocking glasses and computer glasses are a natural sleep aid suitable for men, women and children.
Anti glare, anti fatigue, anti jet lag blue blocker glasses are a safe and comfortable sleep aid that prevents insomnia and other sleep disorders.
Designed for supreme comfort, even when worn for long periods of time.

Figure 1 on the left side is the blue light detection test.

Blue light has a, relatively ,high energy value, of between 400 nm and 480 nm in wavelength. The detection value for ordinary glasses is 0, which means that any wavelength of blue light can penetrate the lens; CGID glasses' detection value is 490, indicating that any blue light with a wavelength of less than 490nm cannot penetrate CGID lenses.

Figure 2 on the left side is the anti-radiation detection.

Electromagnetic radiation is a kind of radiation; its main sources are from home appliances, office appliances, mobile computers and so on. CGID blue light glasses reduce the amount of radiation that may reach and therefore damage our eyes through prolonged contact with such devices.

In the absence of any protection, the detection value is 598 V/m, indicating that the computer screen emits a radiation value of 598 V / m (volts / m); when there are CGID glasses as a barrier, the detection value is 0, indicating that the CGID glasses can effectively block radiation.
