According to Wikipedia, exercise is defined as any bodily activity that enhances or maintains physical fitness, overall health and wellness.
Physical activity may not improve eyesight directly but it plays an important role in reducing the risk of health conditions that are linked to eye disease. Regular exercise helps to control conditions such as type 2 diabetes and high blood pressure both of which can have a direct impact on eye health.
Poorly controlled diabetes can damage the blood vessels in the retina leading to diabetic retinopathy. High blood pressure can also affect the blood supply to the eyes and contribute to vision problems over time.
Studies Based on Exercise and Eye Disease
Numerous studies have shown that regular exercise can reduce the risk of developing certain eye conditions including cataracts, age-related macular degeneration and glaucoma. Below are examples of research relating to exercise and specific eye diseases:
1. Cataracts
A study by Williams PT (2013) showed that regular physical activity such as brisk walking or jogging can reduce the risk of developing cataracts. Other research has also suggested that a lack of exercise may increase the likelihood of cataract formation.
2. Age-Related Macular Degeneration (AMD)
A study by Knutson MD (2006) examined the medical history of over 4,000 individuals to investigate a link between exercise and age-related macular degeneration. The research found that people who exercised three or more times a week were less likely to develop AMD.
3. Glaucoma
A study by Read SA (2011), carried out on young adults with glaucoma, showed that moderate-intensity, low-impact exercise can help to reduce pressure within the eyes. Lowering eye pressure is an important factor in managing glaucoma.
Exercise Tips for Healthy Eyes
Try to make time in your day for regular exercise. Start with simple activities and set realistic goals that suit your lifestyle. Brisk walking or light jogging are effective forms of exercise but if these are not suitable, alternatives such as cycling or swimming can also be beneficial.
Aim to exercise between three and five times a week as part of an overall healthy lifestyle that supports both general health and eye health.
Visit Your Optician
It is important to schedule regular appointments with your optician for a comprehensive eye examination. Routine eye checks help to monitor eye health and ensure that your glasses or lenses are providing the correct prescription.
