H. Chan School of Public Health, Boston, MA, USA Purpose: To validate a paper-based visual acuity (PBVA) questionnaire.Methods: In 2015, a cross-sectional survey was conducted among 301 young and middle-aged, mostly male, Japanese subjects. The participants were asked to self-rate their visual acuity (VA) on a scale from 1 to 5. Self-ratings of VA were categorized into three groups: good (1 and 2), normal (3), and poor (4 and 5). For objective validation, we performed a functional VA (FVA) assessment in the same subjects.Results: A total of 301 subjects answered the PBVA and completed the FVA test including initial VA. We found out that the result of PBVA was significantly correlated with FVA test and initial VA (r=0.33, P

Methods: In 2011, a cross-sectional survey was conducted among all the employees, mainly young and middle-aged Japanese office workers, who used visual display technology, at a company in Osaka, Japan (N=672; age range =26–64 years). The participants were classified according to the Japanese dry eye diagnosis criteria by dry eye examination results including the Schirmer test, fluorescein and lissamine green staining, tear film break-up time, and symptom questionnaire into three groups as follows: definite dry eye disease, probable dry eye disease, and no dry eye disease. To determine sleep quality, Japanese version of the Pittsburgh Sleep Quality Index (global score) was implemented. The global score (range =0–21) was calculated by summing seven sleep variable scores (scale, 0–3); scores ≥5.5 indicated poor sleep. Results: The total mean global score was 5.1±2.3 (completed N=383); 45% of the dry eye disease participants reported having poor sleep quality, while 34% of the no dry eye disease participants did so, with a significant difference found in the global score (P=0.002). Furthermore, a statistically significant association was observed between the global score and dry eye disease (P=0.005). Conclusion: Poor sleep quality is associated with dry eye disease, especially with dry eye symptoms.
