Healthy Vision Habits to Reduce the Risk of Myopia
Myopia, or nearsightedness, has becoming increasingly prevalent worldwide, particularly among children.
Once considered a minor inconvenience easily corrected with glasses or contact lenses, Myopia is now recognized as a significant public health concern. While genetics play a role, lifestyle factors also significantly influence the progression of myopia. Fortunately, there are practical steps you can take to slow its progression and maintain healthier vision.
What is Myopia?
Myopia occurs when the eyeball grows too long, causing light to focus in front of the retina rather than directly on it. This results in blurry vision for distant objects. While corrective lenses can help manage the symptoms, they don’t address the underlying structural changes to the eye, which can continue to grow and worsen as children’s growth hormones are still firing.
As myopia worsens, this elongation increases the strain on various parts of the eye, making it more vulnerable to severe conditions and causing worsening prescriptions (read thicker and thicker glasses). Watch the YouTube video below as Dr. Jesse explains how our eyeball is like pizza dough.
1. Spend More Time Outdoors
Research suggests that spending 90-120 minutes outdoors daily can help slow myopia progression, particularly in children. Sunlight exposure promotes healthy eye development and may reduce eye strain from prolonged near work. Sunlight is brighter than indoor light creating a release of dopamine from the retina. This slows down eye growth, minimizing the risk of becoming myopic. Sunlight promotes the production of Vitamin D which influences refractive development, prevents eye elongation, and stimulates retinal neurons to secrete dopamine (as mentioned earlier) to regulate the sclera. One study discovered that 120min/day of outdoor sunlight exposure (at school) is optimal in reducing myopia prevalence.
2. Reduce Excessive Screen Time
Overexposure to digital screens, especially in children, has been linked to myopia progression. Encourage outdoor activities and limit non-essential screen time, especially before bedtime. Exposure to screens may also interfere with sleep quality, affecting overall eye health. Read more about healthy screen time! In general, doctors recommend:
-
- 0-2 years old: Zero screen time, except for video chatting with family
- 2-5 years old: One hour a day or less, with supervision
- 5-17 years old: Two hours a day or less, except schoolwork

The rising prevalence of myopia among children is a multifaceted problem influenced by modern lifestyles, environmental factors, and educational demands.
3. Take Regular Breaks from Screens and Close Work
Spending long hours on screens or reading without breaks can contribute to myopia progression. The 20-20-20 rule is a great habit: every 20 minutes, look at something 20 feet away for at least 20 seconds. This helps reduce eye strain and encourages the eyes to relax. Play is a powerful tool for children! Read more about how playtime away from screens supports healthy development.
4. Optimize Lighting for Eye Health
Poor lighting can cause unnecessary strain on the eyes. When reading or working on a screen, ensure there’s sufficient ambient light to avoid glare and excessive contrast. Natural daylight is best, but if using artificial light, opt for warm, diffused lighting.
Making these small adjustments can lead to clearer, healthier vision for years to come.
5. Follow an Eye-Friendly Diet
Nutrients like omega-3 fatty acids, vitamin A, lutein, and zinc support eye health. Include leafy greens, carrots, fish, eggs, and nuts in your diet to nourish your eyes and reduce the risk of vision problems. Learn more about foods that can help your brain!
6. Maintain Proper Screen and Reading Distance
Holding screens or books too close can strain the eyes. Maintain at least an arm’s length distance from screens and a comfortable reading distance from books. Adjusting font sizes and increasing contrast can also make reading easier.
7. Ensure Regular Eye Exams
Routine eye check-ups are essential for early detection and management of myopia. An optometrist can provide personalized recommendations, prescribe corrective lenses if needed, and offer strategies like myopia control treatments.
By incorporating these habits into daily life, you can help reduce the risk of myopia and promote long-term eye health.
Why Myopia Management Matters
If your child already has myopia, it’s not too late to help them. Beyond the inconvenience of corrective lenses, myopia poses serious long-term health risks that need to be addressed proactively.
