19 Aug 2025 • A large study has found that poor sleep significantly impacts eye health and glaucoma risk.

Sleeping less than 6 hours was linked to thinning of the retinal nerve fiber layer (RNFL), a key marker of optic nerve damage.

Insomnia increased glaucoma risk by 30% (HR 1.30), while sleep apnea syndrome (SAS) raised it by 43% (HR 1.43), even after adjusting for confounders.

These findings underscore the role of sleep health in retinal neurodegeneration and suggest that incorporating sleep assessment into routine eye care could aid in early detection and prevention of glaucoma.
