In the same way, exercise benefits your overall health, it also benefits your eyes. Exercise leads to a stronger heart and lungs, improved balance, strong muscles and bones, and a healthier body and mind. While you may not often think about how the body and eyes are connected, there are many benefits to exercise for your eyes. And while you can consult an eye doctor in your area by looking at an eye doctor & optometrist list, this article will also discuss how exercise is beneficial to eye health.
1. Exercise Reduces Anxiety
Stress and anxiety can be major contributing factors to vision problems. If you’re stressed and anxious, your body will automatically release the hormone cortisol, which affects the muscles and the eyes. High levels of cortisol can cause severe damage and lead to vision problems. In addition, when you’re stressed or anxious, you’re more prone to experience headaches and migraines. Exercise reduces anxiety by releasing endorphins, the body’s natural pain killer. This leads to a reduction in anxiety and stress and a decrease in the release of cortisol, which leads to better vision.
2. Exercise Improves Vision
When you exercise, your cardiovascular system is strengthened and oxygenated, allowing the eyes to get a better blood supply. Increased blood flow and blood vessels improve your eyesight and keep your vision sharp. The increased blood flow is also beneficial to your overall health, improving your eyesight and other parts of your body. Furthermore, when you exercise, you also have an increased intake of Lutein and Zeaxanthin, which are beneficial to your vision.
3. Exercise Improves Focus
When you exercise, you increase the flow of oxygen to your brain, allowing you to concentrate better. This is especially important for people who work at a computer or do other close work. By staying active and exercising, you prevent your vision from becoming blurry and help improve your focus. The increased circulation helps you synthesize and send more oxygen to your brain, which allows you to concentrate better.
4. Exercise Reduces Eye Strain
While studying, reading, or working on a computer, it is essential to take frequent breaks. Frequent eye strain can lead to permanent vision loss. While your eyes are relaxed and focused on a fixed point, the muscles around them are at a state of maximum contraction.
5. Reduced Risk of Eye Diseases
If you exercise regularly, you may lower your risk of macular degeneration, cataracts, and glaucoma. A study found that people who were physically active at least three days a week had a 25% lower risk of developing cataracts than those who were physically inactive.
6. Reduced Risk of Dry Eyes
Exercising regularly can help prevent dry eyes. When you exercise, you will naturally increase the production of tears. Once you start exercising, it will only take a few minutes for tears to flow from the eyes, thus lubricating the eye’s surface. Also, people who exercise also tend to blink more frequently compared to when they are inactive. Prolonged eye contact is a common cause of dryness, and more frequent blinking will help keep the eyes more moist than usual.
7. Reduced Risk of Macular Degeneration
Being physically active will reduce the risk of developing macular degeneration. By exercising regularly, you increase the flow of oxygen and nutrients to the eyes, which in turn help to prevent the development of macular degeneration. Furthermore, physical exercise promotes the production of growth factors in the eyes, which also help to prevent macular degeneration.
8. Exercise Increases Your Tear Volume and Quality
You may not be aware of this, but tears are essential to the health of your eyes. Tears are secreted by the lacrimal gland, which is located under the upper eyelid and is responsible for keeping the eyes moist. Physically active people have a higher level of tear production. This is because exercise causes increased activity of the lacrimal gland and the meibomian glands, which are responsible for producing the oils that lubricate the eye’s surface. Those who exercise regularly produce more protective, lubricating tears and have a more balanced ratio of oil in the tear film (the layer of oil that coats the eye).
9. Decreased Risk of Degeneration of the Eyes
Exercise reduces the risk of degeneration of the eyes, also referred to as age-related macular degeneration or AMD. Being physically active is known to enhance the function of the retinal pigment epithelium, which serves as a shield against the harmful damage from sunlight, especially ultraviolet radiation.
10. Healthy Blood Flow
Exercise improves blood flow to all parts of your body, including the eyes. This is especially important for the tiny blood vessels in the eye that supply nutrients and oxygen to the eye tissues. A healthy blood supply is crucial for healthy eyes, as a lack of oxygen will cause the eye’s cells to die. In addition, regular exercise increases nitric oxide production in the body, which is a substance that widens blood vessels and improves blood flow.
11. Reduced Risk of Cataracts
Cataracts are a clouding of the lens in the eye. This can result in blurred vision and may eventually lead to complete blindness. Although cataracts are not a normal part of aging, they are prevalent, with 50 percent of Americans developing cataracts before they turn 80. Several studies have found that people who exercise regularly have a significantly decreased risk of cataracts than inactive ones.
12. Reduced Risk of Type 2 Diabetes
Type 2 diabetes is a growing problem in the United States and many other countries due to an increasing number of people becoming overweight and sedentary. In addition to being a risk factor for many other health problems, diabetes is also a significant risk factor for eye disease. Diabetes can directly cause eye diseases such as diabetic retinopathy, the most common cause of blindness in adults and is a significant cause of blindness in children.
13. Reduced Risk of Glaucoma
Glaucoma is the second most common cause of blindness in the U.S. and may result in permanent vision loss. The eye pressure (called intraocular pressure or IOP) rises when blood vessels grow more prominent, become less flexible, and press against the optic nerve. High intraocular pressure damages nerves, thus causing glaucoma. A recent study found that people who were physically active at least once a week had a significantly reduced risk of developing glaucoma compared to those who were inactive. Eye doctors & optometrists provide the best care for eye health.
In conclusion, exercise is beneficial for your eyes and overall health. If you are a student, exercise can make a huge difference in your learning ability and your vision. It’s important to remember that too much of anything can be harmful, so it is best to start slowly while cautious not to overdo it.
