Can More Outside Time Improve Children's Eyesight?

How Screen Time Can Lead to Myopia in Children

Just like muscles respond to how they’re used, children’s eyes adapt to the visual demands placed on them—especially during key stages of development. The challenge today? Many kids are spending a large portion of their time focused on screens.

Whether it’s smartphones, tablets, computers, or handheld gaming devices, these screens encourage prolonged close-up focus. Over time, this “near work” can influence the shape of the eye, causing it to grow too long from front to back.

When the eyeball elongates, light doesn’t reach the retina properly. Instead, it focuses in front of it, leading to blurry distance vision—what we call myopia. While glasses or contacts can correct how a child sees, they don’t reverse the structural eye changes caused by prolonged screen time. That’s why preventive habits and early intervention are key.

Why Early Myopia Management is Essential

Nearsightedness may seem manageable with a simple prescription, but when it begins early and progresses over time, it can put a child at greater risk for long-term eye problems. Advanced myopia has been linked to serious conditions like retinal detachment, macular degeneration, and glaucoma—all of which can lead to permanent vision loss.

In recent years, eye doctors have reported an increase in these complications among children and teens. Many of these cases would have once been considered rare in young patients, highlighting the urgency of addressing myopia early.

At Grene Vision Group, we focus on early detection and ongoing care to help slow the progression of myopia. By monitoring your child’s vision closely and offering personalized treatment options, we aim to protect their eyesight now—and reduce their risk of more serious issues later in life.

Can Outdoor Playtime Help Reduce the Risk of Nearsightedness in Children?

As digital devices become more integrated into kids’ daily lives, many parents are searching for simple ways to protect their child’s vision. One of the most effective—and accessible—solutions is outdoor play. Studies continue to show that spending time outside can significantly reduce the risk of nearsightedness in children. Here’s why time in nature is so beneficial:

• Exposes children to natural lighting 

• Forces children to focus vision on distant objects like trees 

Sunlight is the body’s main source of Vitamin D, which is essential not only for bone and immune health but also potentially for supporting proper eye development. Some studies suggest that natural light helps stimulate dopamine production in the retina, which may help slow the elongation of the eye that leads to myopia.

Outdoor activities also give children’s eyes a break from the constant close-up focus required by screens and books. Whether they’re playing tag, kicking a ball, or simply observing birds in the sky, outdoor play naturally strengthens distance vision. Experts have found that as little as 76 minutes of outdoor time each day may lower a child’s chances of developing myopia by up to 50%. Making time for outdoor adventures isn’t just good for the body—it’s great for the eyes, too. 

Simple Ways to Protect Your Child from Myopia Development

At Grene Vision Group, we know how important your child’s eye health is to you. The good news is that a few everyday habits can go a long way in reducing the risk of nearsightedness or slowing its progression. Here are some practical steps our experts recommend for maintaining healthy vision at home: 

Be Mindful of Screen Time

While digital devices have become part of modern life, prolonged screen use can place unnecessary strain on developing eyes. Extended time spent focusing on close-up screens—especially without breaks—can encourage the onset of myopia.

To help protect your child’s eyesight, follow age-based screen time guidelines. Children under two should avoid screens except for video chats, ages two to five should be limited to one hour daily, and older kids should keep recreational screen time to no more than two hours per day. 

Encourage Daily Outdoor Play

Spending time outdoors supports visual development by giving eyes the opportunity to focus on faraway objects and absorb natural light. These two factors are shown to help reduce the risk of developing myopia.

Aim for about two hours of outdoor play each day. Whether it’s riding bikes, playing sports, or enjoying a family walk, consistent time outside can have a big impact on eye health—and it’s great for overall wellness, too. 

Practice the 20/20/20 Rule

To help ease the strain of screen time, teach your child the 20-20-20 rule: every 20 minutes, look at something at least 20 feet away for 20 seconds. This quick reset helps reduce fatigue and supports healthy focusing habits.

Using a timer or fun reminders can make it easier for kids to remember. Over time, this small habit can turn into a lifelong practice that promotes long-term vision wellness.
