Researchers in Australia randomly assigned more than 600 elderly men and women either to receive eye exams and vision correction or not.
Within the next year those who received treatment were 57% more likely to fall, and 74% more likely to break a bone than the untreated participants.
Researchers think elderly patients may need a longer time to adjust to the improved vision, or could take more physical risks after seeing better.
This may come as no big surprise, but offering some help around the house to an elderly parent or loved one could greatly reduce their risk of falling.
Researchers in Oregon found elderly men are much more likely to suffer a fall while doing household chores like cleaning gutters or shoveling snow than more leisurely activities.
The study looked at almost 6,000 men 65 and older and their lifestyles.
More active men had a greater risk of falling than the more sedentary men.
