The first reader to weigh in on a recent post about new fall-prevention guidelines was “h” from Chicago, who wrote: “I also wonder about bifocals causing falls. This is why I’m sticking to two pairs of glasses for now.”

That’s good advice, it turns out.

In a study published last year in the medical journal BMJ, Australian researchers found a decrease in the number of falls among people who switched to single-vision eyeglasses for outdoor activities and stairs.

The results, said the researchers, “demonstrated how multifocal glasses can impair visual abilities needed for detecting obstacles and judging depth.”
