: level of statistical significance in comparison between groups using Mann-Whitney nonparametric test. Bold text shows the statistically significant results ().
RV: Radner-Vissum reading test; MRS: maximum reading speed; wpm: words per minute; F: photopic luminance; CSV: CSV1000E contrast sensitivity test; M + G: mesopic luminance with glare condition; cpd: cycles per degree (spatial frequency); CCI: confusion color index; F-D15: Farnsworth-panel D15; L-D15: L’Anthony desaturated D15; SD: standard deviation.
