Now that myopia (nearsightedness) is reaching epidemic proportions across the globe, it’s all the more important for parents to understand how myopia can impact their child’s future, and learn which actions they should take to protect their child's eye health in the long run.
You see, myopia isn't simply an inconvenience. Childhood myopia raises the risk of developing vision-robbing diseases like macular degeneration, cataracts, glaucoma, retinal detachment and diabetic retinopathy later in life.
Myopia develops as the eye elongates more than it should, causing light to focus in front of the retina instead of directly on it. This manifests as blurred distance vision and clear near vision.
While myopia is caused by a combination of circumstances, including genetic and environmental, a key factor comes down to the amount of time a child spends outdoors in the sunlight.
How Does Outdoor Play Affect Myopia?
Although researchers haven’t yet pinpointed exactly why “sun time” prevents or delays myopia, almost all agree that it plays a large role.
One possible reason is correlated to the brightness of the sun. Some experts have found that the intensity of the sun’s rays triggers a dopamine release in the retina which is thought to slow down the elongation of the eye.
Another theory holds that outdoor time encourages a child to shift their gaze from near objects to faraway ones. Excessive near work, like staring at a digital screen, is believed to be a driving force behind the stark increase in myopic individuals today.
Sending a child outdoors to play gives their eyes a break from focusing on their tablets, smartphones, homework, gaming and other near work.
Additionally, spending more time in the sunshine means more Vitamin-D production. Small-scale studies have found nearsighted people have lower levels of Vitamin D than those with normal eyesight. However, more research is needed to confirm this theory.
Here's the Bottom Line
Childhood myopia increases the risk of developing sight-threatening eye diseases later in life. Parents should be proactive about their child’s eye health and do what they can to prevent myopia from developing or progressing at a rapid rate.
Even if your child doesn’t have myopia, encouraging them to play outdoors for several hours a day has been found to prevent the onset of myopia in certain instances.
So go ahead and give your child a water bottle, sunscreen, a pair of sunglasses—and send them out to play! Children aged 6 and up should spend about 2 hours daily outside in the sunshine.
But sun time alone isn’t enough to ensure the best possible outcome for their eye health. A myopia management program can help give your child the best odds of healthy vision for a lifetime.
