Abstract

Background: Visual perception has hindered the development of blinded, placebo-controlled ultraviolet light exposure conditions in humans. New acrylic thermoplastics that block or transmit ultraviolet light have visual properties that may provide a solution. Methods: In a series of triangle taste tests, 60 subjects were tested for the ability to visually perceive ultraviolet light transmission by two of four types of acrylic thermoplastics. Results: Forty-six of sixty (67%) subjects were unable to visually detect ultraviolet light transmitting acrylics among ultraviolet blocking acrylics in both an ambient light background condition and an ambient light background condition with ultraviolet A light supplementation. Conclusion: Acrylic thermoplastics allow for the production of blinded, placebo-controlled ultraviolet light exposure conditions by eliminating visual discrimination differences between active and control groups.
