This study aimed to determine the effects of reading on non-invasive tear break-up time (NIBUT) in soft contact lens wearers and establish the correlation between the Contact Lens Dry Eye Questionnaire-8 (CLDEQ-8) and the NIBUT before and after reading. The demographic questionnaire, Contact Lens Dry Eye Questionnaire-8 (CLDEQ-8), were completed by 18 soft contact lens wearer (36 eyes; 17 females and 1 male). The NIBUT was measured as a baseline using modified bowl perimetry before reading. The subjects were then instructed to read silently for 20 minutes a validated hard copy text. The NIBUT test was administered again following the reading task. This study enrolled a total of 18 contact lens wearers (36 eyes). The mean age of the participants was 22.89 ± 1.687 years, and the mean refractive power of their contact lenses ranged from Plano to -5.75D (1.44 ± 0.504D). Twenty-five eyes (55.6%) of contact lens wearers wore lenses less than -3.00D, while sixteen eyes (44.4%) wore lenses g.....
