Abstract
A surgical drape manufactured or fabricated from a polymeric film having a low glare finish and a predetermined coloration for reducing the luminous intensity of light reflected from the surface thereof is provided. Such surgical drape thereby minimizes reflectivity therefrom, and thus eye strain and fatigue. The subject invention includes the use of colorants, dyes, pigments, etc. to form translucent polymeric surgical drapes that absorb a selected range of wavelengths from surface reflected light. More particularly, the use of coloring agents in combination with a textured surface yield a surgical drape possessing reduced luminance and glare, thereby mitigating eye strain and fatigue. The preferred range of reflected light, in order of preference, is 625-700 nm, 520-560 nm, 450-520 nm, 400-450 nm, 600-625 nm, and 560-600 nm.
