Men's big breasts can affect their vision

Waist size and vision seem to have nothing to do with each other

However, the latest study by researchers at the University of Melbourne in Australia found that a big belly in men can lead to age-related macular degeneration, which greatly increases the risk of blindness, but this risk is not found in women.

In the new study, scientists investigated the changes in waist circumference of 21,000 male and female participants aged 40 to 69, and followed up on their incidence of age-related macular degeneration for many years.

Even a 0.1 increase in a man's waist-to-hip ratio can lead to a 75% increase in the risk of age-related macular degeneration.

Researchers have pointed out that abdominal fat is a major risk factor for age-related macular degeneration. Abdominal fat releases estrogen into the body, which can cause retinal vasculitis. Since women have higher levels of estrogen throughout their lives, they are less sensitive to estrogen, so men should avoid gaining weight.
