The specific wavelength of light of the anti-blu-ray glasses can block the passage of light of another wavelength, acting as an interceptor. Anti-blue-light glasses work by blocking and reflecting high-energy short-wave blue light through lenses of special materials. Blue-light resistant glasses with yellowed lenses can prevent blue light from passing through. Blue light is one of the number one killers of lutein, long-term exposure to the eye will cause lutein to deteriorate and eventually damage the macula of the eye. Want to buy eyeglasses at Zinff.

What principle do eyeglasses use?
Eyeglasses work using the principle of refraction. Refraction means you are bending light. To focus light into a point means to converge it, while scattering light means to diverge it. Farsightedness and presbyopia require converging lenses to bend the light sooner and shorten the focal distance, while nearsightedness requires diverging lenses to make the light converge later and lengthen the focal distance. So eyeglasses move the point where the light rays come together so the light can focus directly on the retina. The retina is the sensitive part of the eye that perceives light and sends it to the brain.
Why do you think eyeglasses were invented before the microscope?
