shows a large spread of PRT data obtained at 40% RH compared with 5% RH. The mean PRT value decreased from 26 ± 9 in normal conditions (40% RH) to 22 ± 4 mm in dry conditions (5% RH). However, this reduction in tear production did not reach statistical significance (p = 0.24). An increase in wetting length at protection and relief was seen compared with both normal and dry conditions. However, repeated measures ANOVA test showed no statistically significant differences in tear production (p > 0.05). The mean value of PRT was 25.7 (p = 0.059) in protection and 24.9 mm (p = 0.32) in relief
