There is no debate that climate change is terrible for the planet and its effects are undeniable. The negative impacts of global warming on people will only become more prominent. According to research in the United States, elderly persons living in areas with an average temperature of 15.5 degrees Celsius are more likely to experience blindness or vision problems, even with glasses, according to a study involving 1.7 million people.

Esme Fuller-Thomson, co-author of the study said, "The link between vision impairment and average county temperature is very worrying if future research determines that the association is causal."

With an increase in temperature, the likelihood of significant vision impairment rose when compared to regions with average temperatures under 10 degrees Celsius. This was 24% higher in areas where the average temperature was from 12 to 15 degrees Celsius, and it was 14% higher for inhabitants where the average temperature was between 10 and 12 degrees Celsius. Living in a warmer climate increases the risk of eyesight loss by 44%

The relationship between higher temperatures and vision impairment persisted even after age, sex, and wealth were considered. Compared to persons 80 and older, the connection was stronger among those in the 65 to 79 age group.

Additionally, men were more aware of this trend than women were. Even then, the association hasn't been verified by scientists. The research team suggests that it may be brought on by increased exposure to UV light, air pollution, infections, and folic acid breakdown when combined with warming temperatures.
