Effects of regular spectacle wear on binocular accommodative function in myopic adults with dry eye disease.

OBJECTIVE

To evaluate the impact of regular refractive correction (spectacle wear) on dry-eye-related parameters and binocular visual function in myopic adults with coexisting dry eye disease (DED).

METHODS

A cross-sectional observational study enrolled 120 myopic patients with DED, divided into a regular spectacle-wear group (n = 68) and a minimal/non-wear group (n = 52) based on daily spectacle wear duration. Dry eye parameters including tear meniscus height (TMH) and average tear break-up time (Ave TBUT), binocular accommodative function parameters including positive and negative relative accommodation (PRA/NRA), monocular and binocular accommodative facility (AF), and Ocular Surface Disease Index (OSDI) scores were assessed. Correlations between Ave TBUT, TMH, and binocular accommodative function were analysed.

RESULTS

The regular spectacle-wear group showed significantly longer Ave TBUT and lower OSDI scores (p < 0.05), with no significant TMH difference. Binocular accommodative function was better in the regular spectacle wear group, with significantly lower PRA, higher NRA, and greater monocular/binocular AF (all p < 0.05). Ave TBUT was negatively correlated with PRA and positively correlated with NRA and AF (p < 0.05); TMH showed no significant correlations.

CONCLUSION

Regular spectacle wear is associated with improved tear film stability, reduced dry-eye symptoms, and enhanced binocular visual function in myopic patients with dry eye.
