Small portions of alcohol can reduce the risk of deterioration of vision in old age

Visual impairment can often be caused by eye disease, trauma, as well as by a congenital or degenerative condition, and it can not be corrected with glasses or contact lenses. It leads to a decrease in the quality of life, and in severe cases to a loss of independence.

Scientists have identified a link between small doses of alcohol and vision in old age

Researchers from the College of Medicine and Public Health at the University of Wisconsin studied the relationship between prevalence visual impairment and three human habits that are amenable to change, namely, smoking, alcohol and physical activity.

A study published in the journal of the American Academy of OphthalmologyOphthalmology, was carried out as part of a long-term studyBeaver Dam Eye Study, held from 1988 to 2013, with the participation of almost , 00 people aged 43-84 years.

The researchers found that in 20 years, vision deteriorated in% of the population and varied depending on lifestyle habits.

They found a deterioration in vision in 2% of physically active people compared with,% of people leading a sedentary lifestyle. The result after the adjustment for age showed that people who lead a physically active lifestyle have 58% less chance of deteriorating their vision compared to those who lead a sedentary lifestyle.

As for the occasional drinkers, that is, those who drank less than one serving of alcohol per week on over 20 years, vision deteriorated in% of participants compared to 11% of people who did not drink alcohol at least a year. And again after the correction for age - 49% decrease in the likelihood of deterioration in sight of those who drank occasionally, compared with those who did not drink.

According to the lead researcher, as a rule, one of the most heavily related factors for many eye diseases that cause vision impairment is age, and it can not be changed. And lifestyle habits, such as smoking, drinking alcohol and physical activity, can be changed. Thus, the fact that they are associated with a deterioration in vision in the long term, is reassuring in terms of possible prevention. However, further research is needed to determine if a change in these habits will lead to a direct reduction in vision impairment.
