Natural eye protection: Get kids outside to prevent nearsightedness - Children's National

Is getting your kids off their devices and outside a constant battle? Here is some motivation to keep fighting the good fight: spending at least two hours outdoors every day is one of the most important things your child can do for their eyesight.

Myopia on the rise in children

The number of children with nearsightedness, or myopia, is growing rapidly. In the United States, 42% of people are now myopic, compared to just 25% in the 1970s. In some parts of the world, this number is even more alarming, with up to 90% of young adults being nearsighted.

The long and short of myopia

Myopia occurs when the eyeball stretches and grows too long, making distant objects blurry. Once this happens, the eyeball continues to stretch, worsening the condition. High myopia can increase the risk of serious eye problems later in life, such as retinal detachments, glaucoma and cataracts.

The great outdoors to the rescue!

So how does spending time outside help? Research suggests it has to do with sunlight, and, importantly, relief from constantly focusing on near objects like a phone screen. Sunlight stimulates the eye to release a neurotransmitter called dopamine, which helps prevent the eyeball from stretching. Studies have shown that children who spend more time outdoors are less likely to develop myopia. Looking away into the distance relaxes the internal focusing muscle of the eye. If you are tied to a screen for school or work, take 10 minutes off every hour and look outside into the distance.

Make every day an outdoor adventure

The good news is, it does not matter if it is sunny or cloudy, or what your kids are doing outside. Playing at the park, riding bikes, exploring nature - it all counts! Let them do their homework outside if that is what it takes. As long as they are getting their daily dose of sunshine, their eyes will thank you for it.

Keep in mind that the two-hour recommendation is a general guideline. Toddlers may do better with shorter bursts of outdoor time throughout the day, while older children can handle longer stretches.

Remember:

• At least 2 hours of outdoor time each day is recommended.
• The earlier you start, the better.
• Every bit counts - parks, playgrounds, nature walks, even your backyard!

So, ditch the screens, embrace the sunshine and protect your child's precious gift of sight! And don't forget to schedule regular eye exams for your children!
