Researchers from Canada came to the conclusion that people aged 65 who live in warmer places.
Are more likely to have significant vision impairment than those who live in cooler regions.
This was discovered in a recent survey that involved 1.7 million senior citizens in the United States.
The "Ophthalmic Epidemiology" journal is the one that publishes it.
Those who lived in counties with an average temperature between 10 and 12 degrees Celsius.
Had a 14 percent increased risk of severe vision impairment, those who lived in counties with an average temperature between 12 & 15.55 degrees Celsius had a 24 percent increased risk.
Those who lived in counties with an average temperature of 15.5 degrees Celsius or higher had a 44 percent increased risk.
According to the first author of the study, "If future research proves causal, this link between vision impairment and average country.
Temperature is very worrying." [C] Consideration should be given to whether or not this link exists.
