How Does Photophobia Glasses Work?
The visible light spectrum is made up of all the colors in the rainbow. Red light waves sit to the left; as you move to the right, there is orange, yellow, green, blue. And violet light, with other colors in between. The light resides along the visible light spectrum according to how long their wavelengths of energy are. UV light has the shortest wavelength and red has the longest.
However, UV light carries a significant amount of energy that can damage and burn our eyes. So, the indoor sunglasses for light sensitivity are designed to filter out and block blue-green wavelengths, fluorescent light, LED lighting, bright sunlight and other reflective lights that may affect the eyes.

The current multi-layer anti-reflection film thickness is about 0.3μm.
