Myopia, or nearsightedness, is a common vision problem affecting millions worldwide. It is a condition in which the eye cannot focus on distant objects, resulting in blurred vision. While eyeglasses, contact lenses, or surgery can help correct nearsightedness, recent research suggests that spending more time outdoors may help prevent or slow its progression.

What Is Myopia?

Myopia is a condition in which one cannot see distant objects clearly. This condition results from the elongation of the eye, making the retina less sensitive to light. That leads to blurred vision when looking at objects far away. Myopia usually develops in childhood and adolescence, becoming more prevalent in recent years.

The Link Between Outdoor Time and Myopia

Studies show that kids who spend more time outdoors have a lower risk of developing myopia. One theory is that increased exposure to natural light and the increased distance the eye must focus on may help slow the elongation of the eye. Also, outdoor sports and play promote healthy eye development.

How Much Outdoor Time Is Enough?

Experts have yet to establish the amount of outdoor time needed to prevent or slow myopia progression. However, research suggests that at least two hours of outdoor time per day may be beneficial. That may include time spent playing sports, walking outside, or engaging in other outdoor activities.

The Role of Ultraviolet Light

Ultraviolet light is a type of light present in natural sunlight. Studies show that UV light may have a protective effect on the eyes. That may help prevent the development of myopia. UV light may also help regulate the release of certain hormones involved in eye growth.

Other Factors That May Affect Myopia

While outdoor time is essential, it is not the only factor that affects myopia. Other factors such as diet, genetics, and the amount of near work may also play a role. It is essential to consider all of these factors when trying to prevent or slow the progression of myopia.

How to Incorporate More Outdoor Time

It might be simple to add more outdoor time to your regular schedule. Simple changes like taking a walk during lunch, going for a bike ride after work, or playing sports on the weekends help increase your outdoor time. Also, limiting the amount of near work and taking frequent breaks can help.

Conclusion

Millions of people all around the world suffer from the eyesight issue known as myopia. More research is necessary to get the exact link between outdoor time and myopia. It is clear that getting outside and spending time in natural light can positively impact eye health. It is best to ensure you get enough outdoor time to protect your eye health and vision. You should also limit near work and other factors that may affect myopia.
