ABSTRACT:
A method and apparatus for enhancing the vision of an individual viewing an object through an optical path through water. The method includes filtering the light that enters one eye of the individual to effect subtractive filtration to compensate for differential light absorption of water, and filtering light that enters the second eye of the individual which does not compensate for the differential light absorption of water. The apparatus includes two light transmitting elements, one of which filters light to effect subtractive filtration to compensate for differential light absorption by water and the other of which does not compensate for the differential absorption of light by water.
