The Sleep–Vision–Nutrition Trio

When it comes to childhood myopia, genetics and screen time aren’t the whole story. Emerging research shows that sleep quality and nutrition also play powerful roles in eye growth and visual development. Together, sleep, vision, and nutrition form a modifiable trio that supports both eye health and overall wellbeing.

Sleep isn’t just important for mood and learning - it matters for the eyes, too. Studies suggest that children with myopia often have disrupted sleep rhythms, including later melatonin release. When melatonin and dopamine fall out of sync, the eye’s natural “braking system” that helps control eye growth may not work as well. It’s no surprise that kids who sleep very little are more likely to develop myopia.

Nutrition can help support healthier sleep and visual development. Vitamin D, magnesium, omega-3 fatty acids, and lutein and zeaxanthin all contribute to better sleep quality, mood regulation, and retinal health. Myopia progression can also be influenced by dietary patterns, metabolic stress, and environmental light exposure. Diets high in refined carbohydrates may increase blood sugar and insulin levels, triggering growth signals and inflammation that can interfere with dopamine’s protective role in eye development.

The good news? Sleep habits, diet choices, and daily light exposure are all things families can influence. Small changes can make a meaningful difference in supporting healthy vision as children grow.
