Hot weather impacts vision impairments

A correlation between high temperature regions and severe vision impairments was found in US people aged 65 and over by researchers at the University of Toronto. 

A study, published in the Ophthalmic Epidemiology journal, revealed that elderly people experienced a 14% higher chance of severe impairment at 50– 54.9F compared to colder climates, while those living in temperatures of 55-59F had a 24% higher risk, and those at 60F or above had a 44% (15.5C) higher risk.  

Findings showed a stronger relationship among individuals aged 65 to 79 compared to those aged 80 or older, with males at higher risk than females.
