This survey research systematically collects Information on the long term effects of Irlen tinted lenses, from a specific diagnosed scotopic sensitive population. The survey used is based on Whiting's survey (1988), with variations and extensions made to increase information attained. Although the main focus of the survey is reading and related academic skills, other areas presenting new directions for further research, have also been included. 306 diagnosed scotopic sensitive Individuals, who had been using prescribed Irlen tinted lenses for a minimum of six months, were surveyed. 82.8 percent of the respondents indicated that they (or their child) had experienced great benefits from wearing Irlen tinted lenses. 70.1 percent Indicated that the greatest benefit had been in the area of reading. Cross-tabulations were made with length of time wearing the lenses, gender, and whether the respondent was filling in the questionnaire for themselves or for their child. The results of this descriptive research support Whiting's (1988), earlier findings. A review of the available literature and the Implications of these findings are discussed.
