Bottom Line: All the employees of a company in Osaka, Japan. 672 Japanese office workers using Visual Display Terminals (age range: 26-64 years).Of the 672 workers, 561 (83.5%) completed the questionnaires and examinations.The mean Subjective Happiness Scale score was 4.91 (SD = 1.01).

ABSTRACT

Importance: Dry eye disease has become an important health problem. A lack of concordance between self-reported symptoms and the outcome of dry eye examinations has raised questions about dry eye disease.

Objective: To explore the association between subjective happiness and objective and subjective symptoms of dry eye disease.

Design: The study adopted a cross-sectional design.

Setting: All the employees of a company in Osaka, Japan.

Participants: 672 Japanese office workers using Visual Display Terminals (age range: 26-64 years).

Methods: The dry eye measurement tools included the Schirmer test, conjunctivocorneal staining, the tear film break-up time, as well as the administration of a dry eye symptoms questionnaire. Happiness was measured by the Subjective Happiness Scale.

Main outcome measures: Dry eye examination parameters, dry eye symptoms questionnaires, and the Subjective Happiness Scale score.

Results: Of the 672 workers, 561 (83.5%) completed the questionnaires and examinations. The mean Subjective Happiness Scale score was 4.91 (SD = 1.01). This score was inversely correlated with the dry eye symptom score (r = -0.188, p < 0.001), but was not associated with objective findings which include conjunctivocorneal staining, low Schirmer test score, or low tear film break-up time. The level of subjective happiness was the lowest in the group without objective results, but reported subjective symptoms of dry eyes (p < 0.05).

Conclusions and relevance: There is evidence of the relationship between subjective happiness and self-reported symptoms of dry eyes. Findings of this study revealed a new perspective on dry eye disease, including the potential for innovative treatments of a specific population with dry eye disease.

Mentions: The SHS scores of the participants in the Objective (+)/Subjective (-) classification were significantly higher than were those of the Objective (-)/Subjective (+) and the Objective (+)/Subjective (+) groups (F = 6.18, p<0.05, Fig 2). In contrast, the SHS scores were significantly lower for the participants in the Objective (-)/Subjective (+) group than they were for participants in every other group, including the participants with “definite DED” (i.e., Objective (+)/Subjective (+)) (p<0.05, Fig 2).
