Children’s Eye Health and Safety Month: Interview with Margaret Livingstone

Margaret S. Livingstone, Ph.D., is a neurobiology professor at Harvard Medical School and a member of the Dana Alliance for Brain Initiatives. Since August is Children’s Eye Health and Safety Month (sponsored by Prevent Blindness America), we decided to check in with Dr. Livingstone, a vision expert.

Livingstone has done extensive work with primates and is the author of the book Vision and Art: The Biology of Seeing.

When asked about tips for maintaining optimal vision, Livingstone referenced research by Torsten Wiesel and Elio Raviola on myopia (nearsightedness) in monkeys. “You shouldn’t overcorrect myopia. Kids who do a lot of close work will become myopic and if you keep correcting them they’ll get more and more myopic. My kids didn’t ever wear glasses when they read even though they were both slightly nearsighted. They are still slightly nearsighted but they are not profoundly nearsighted like I am.”

There is a growing concern over the amount of time kids spend in front of screens—playing videogames, on the computer, watching television—and whether this could cause nearsightedness. There is debate over the effects of such behavior, but Livingstone sides with the conclusion of a 1996 study that found close exposure to various screens (e.g. sitting too close to the TV) is no different than other forms of “near work.” These activities “will certainly rearrange the way their brains are organized,” Livingstone said. “But so does everything we have intensive early experience with. It’s not harmful, it’s just different.”

  1. Children’s eye care is really important, as a mother of 3 I’m am totally responsible for ensuing their eye health. I also found some really helpful information on the vision express website, they have a really good specific childrens area, couple that with your advice and I feel far more assured.
