| Abstract: |
An article of externally-worn eye wear, including, but not limited to, eyeglasses, sunglasses, goggles, and contact lenses. The eye wear includes a wavelength transmission blocker for blocking substantially all of light wavelengths throughout the blue light spectrum. The wavelength transmission blocker protects the eyes against the harmful effect of the blocked light. Also, since the eye wear is worn externally from the eye, and the user can remove the eye wear, the user can selectively block the light. As such, the eye wear can be worn to block potentially harmful light, or the eye wear can be removed if blocking the light would cause other hazards.
