In a recent article from The Conversation, a British academic writes, “We know that spending greater time outdoors (90 minutes a day) seems to reduce the risk of developing myopia. Why this works is not clear. The most recent research suggests that it may be the lack of visible violet light indoors that causes the problem.”

The piece recaps the alarming surge in myopia over the past generation and the increasing body of scientific evidence pointing to the time-sucking use of screens by youngsters, effectively keeping them indoors for much of their early developmental years.

As other researchers have suggested, what seems to be radically accelerating myopia’s progress is the lack of violet light our children are exposed to, as they spend their childhood playing indoors.  The piece goes on to note, “The LEDs and fluorescent lights often used in our homes and schools contain little violet light, and violet light does not pass through materials such as the UV-protected spectacles and the glass in windows.”

With Daylight Savings Time back on, there’s an extra hour of daylight available to our patient families to get the kids out enjoying some of that natural violet light. And we know firsthand how tough it can be to make time for outdoor play in our time-starved, over-scheduled lives. But, especially during the critical eye development years between 6 and 15, we encourage all parents to strive to make the time – for the sake of your child’s long-term vision health.
