How Do Blue Light Blocking Glasses Work?

The light of a specific wavelength of the anti-blue light glasses can   prevent   the   light   of another wavelength from passing through, which plays an interception role.   The working principle of anti-blue light glasses is to block and reflect high-energy short-wave blue light through lenses made of special materials. Blue light   blocking glasses have yellow lenses to prevent blue light from passing through.

Blue light is one of the number one killers of lutein. Long-term exposure to the eyeball will lead to the deterioration of lutein and eventually damage to the macula of the eye.

Anti-blue light glasses can protect the eyes to a certain extent, especially for groups who stare at electronic screens for a long time. However, when choosing blue light glasses, you must pay attention to the fact that the glasses must have an authoritative inspection mark.

The lenses are generally light yellow, and the glasses are effective when the blocking rate of blue light reaches more than 97% effect is not obvious.
