(a) Effect of window films, electrochromic (EC) glass, and fabric shade materials on visual acuity tested by a computer adaptation of the Snellen chart. Visual acuity represented by mean of LogMAR scores and standard error of the mean bars. ns annotations represent non-significant pairwise comparisons between materials (Supplementary Information online, Appendix D). Bar color represents material color. Film and EC glass versus fabric shade type yield better visual acuity performance; (b) Effect of window films, electrochromic (EC) glass, and fabric shade materials on contrast sensitivity tested by a computer adaptation of the Pelli-Robson chart. Contrast sensitivity represented by mean of sensitivity scores and standard error of the mean bars. ns annotations represent non-significant pairwise comparisons between materials (Supplementary Information online, Appendix D). Bar color represents material color. Film and EC glass versus fabric shade type yield better contrast sensitivity performance.
