Research Article: Effects of regular spectacle wear on binocular accommodative function in myopic adults with dry eye disease
Abstract:
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).
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.
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.
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.
Introduction:
Myopia is the most prevalent refractive error globally, and its prevention, control, and visual health management represent a critical public health issue ( 1 ). According to World Health Organization projections, the global myopic population will reach 4.76 billion by 2050. Among these individuals, those with high myopia face a significantly increased risk of vision-threatening fundus pathologies such as macular degeneration and retinal detachment ( 2 ). Spectacles (glasses), being the most common optical…
