The belief that looking at green scenery can improve eyesight has long been a topic of interest and debate. Many believe that spending time in nature, particularly in green spaces like parks or forests, benefits eye health and overall vision. However, this notion remains under scrutiny, with many questioning whether it’s a myth or a fact. To get a clearer understanding, the OnlyMyHealth team spoke with Dr Aditi Sapovadia, Paediatric Ophthalmologist and Squint and Cataract Consultant at Netradeep Maxivision Eye Hospital, Rajkot, for her expert insights.

According to Dr Sapovadia, spending time in green environments has not been directly proven to improve eyesight, but it can be beneficial for overall eye health, particularly for children.
"Studies suggest that outdoor activities, especially in natural light, can help reduce the risk of myopia (nearsightedness), which is becoming increasingly common. Exposure to natural light and looking at distant objects while outdoors may reduce eye strain and encourage proper development of vision in children," she says.
In fact, a study published in the JMIR Public Health Surveillance found that students who attended schools with more green space were less likely to develop myopia. Researchers noted that a 1-unit increase in the myopia-related green space morphology index was associated with a 9.8% reduction in the risk of developing myopia.
Dr Sapovadia further adds that for adults, while green environments may not directly improve vision, spending time outdoors can help reduce eye fatigue from prolonged screen time and provide relief from digital eye strain.
How Does Spending Time In Green Environments Benefit Eye Health?![]()
In general, indulging in outdoor activities and spending time in a green environment can benefit the eyes in several ways, says Dr Sapovadia. These benefits include:
Reduced myopia risk: For children, spending more time outdoors in natural light can lower the chances of developing myopia. The exposure to sunlight and the opportunity to focus on distant objects are believed to contribute to healthier eye development.
Less eye strain: Outdoor activities allow the eyes to relax, especially after long periods of focusing on nearby objects like screens or books. This can reduce eye fatigue and discomfort, which are common symptoms of digital eye strain.
Exposure to sunlight: Moderate exposure to sunlight helps regulate the body’s circadian rhythm and may contribute to overall well-being, including eye health. However, it’s important to protect the eyes from excessive UV exposure by wearing sunglasses with UV protection.

Other effective ways to improve eyesight and overall vision include:
- Visiting an eye specialist regularly ensures early detection and management of vision problems or eye conditions.
- The 20-20-20 Rule, especially for those who spend long hours in front of screens; it’s recommended to take a break every 20 minutes, look at something 20 feet away for 20 seconds, to reduce digital eye strain.
- Consuming foods rich in vitamins A, C, and E, as well as omega-3 fatty acids, lutein, and zinc, helps support eye health. Leafy greens, carrots, citrus fruits, and fish are particularly beneficial.
- Ensuring good lighting while reading or working on a computer can reduce eye strain.
- Using sunglasses that block 100% of UVA and UVB rays can protect your eyes from sun damage.
Conclusion
While there is no scientific evidence to support that spending time in green environments directly improves eyesight, experts suggest that outdoor activities, in general, can help reduce prolonged screen exposure and alleviate eye strain, especially in children. Additionally, there are several proven ways to support vision and overall eye health. If these measures don't provide relief, it’s always advisable to consult an ophthalmologist for proper guidance and treatment.
