Step 2: Place the glasses in front of the display screen, or check under the LED light to see if blue light is reflected on the surface of the lens, indicating that the blue light-proof glasses can block blue light.
Step 4: You can buy an anti-blue light test card for testing. High-quality anti-blue glasses will not transmit harmful blue light under the irradiation of the test pen.
Step 5: You can go to a professional optical shop for testing.
Generally speaking, the three most important data for anti-blue glasses lenses are anti-blue light rate, light transmittance, and chromatic aberration. Among them, the anti-blue light rate generally needs to be above 35%, the light transmittance needs to be maintained above 90%, and the chromatic aberration is as low as possible.
