The present invention relates generally to optical lenses, and more particularly to externally-worn optical lenses which are designed to minimize glare, contrast sensitivity, chromatic and spherical aberrations and color distortion while maximizing visual acuity and blockage of a predetermined percentage of light wavelength transmission throughout the blue light spectrum.
