An article of an eye wear worn externally upon an eye, having an article which article comprises a wavelength transmission blocker. The wavelength transmission blocker has a lutein assimilated therein for preventing radical damage in the eye. The wavelength transmission blocker is sized and configured to maximize visual acuity and block at least 80 % of light wavelengths throughout a blue light spectrum set in a range from about 400 nm to about 510 nm. Preferably, the wavelength transmission blocker is operative to block substantially 100 % of light wavelengths lower than 420 nm, and to block about 99 % light wavelength at 420 nm and about 20 % of light wavelength at 510 nm. Preferably, the wavelength transmission blocker blocks a gradually reduced percentage of light wavelengths between 420 nm to 510 nm. The wavelength transmission blocker is also operative to block a portion of light wavelengths between 510 nm to 650 nm. |
