How the eye work? Can you change eyeball’s size?
Do eye exercises improve vision? First, you have to understand how the eye works and what’s the role of eyeball’s size to eye problems.
Most common eye conditions, such as nearsightedness (myopia), farsightedness (hyperopia) and astigmatism are the aftermath of the irregular size of the eyeball or irregular shape of the cornea.
In nearsightedness (myopia), or farsightedness (hyperopia) eyeball is either too small or too big. So, the light rays entering your eye don’t focus on the retina. They focus either beyond, either after the retina.
In astigmatism, usually, your cornea has an irregular shape, causing light rays entering your eye to split into different points of focus. The aftermath is blurry vision.
In presbyopia, a near vision problem that occurs to people in their forties, the eye’s natural lens starts to lose elasticity. Then the lens can’t move properly to focus on close-up objects.
The Bates method for better eyesight without glasses
The father of eye exercises to through away glasses is an eye-care physician named William Horatio Bates. He believed that glasses were harmful and he taught people methods to see without glasses. His method, known as “Bates Method”, is described in his popular book “Perfect Sight Without Glasses“.
Bates’s method became popular in around 1920. The Bates Method has never been proven effective in providing significant or lasting vision improvement.
His techniques had to do about visualization and movement. He placed particular emphasis on imagining black letters and marks, and the movement of such. The scariest part though, of the Bates method, is that he suggested people to expose their eyes to direct sunlight.
Most modern programs of eye exercises to improve vision are based, at least in some percentage, on the Bates Method.
Typical eye exercises
Eye exercises probably won’t improve your eyesight, and certainly won’t help you to such an extent as to see without glasses. On the other half, eye exercises can confort your eyes, especially if you stare at a computer or smartphone screen for many hours.
Most common eye exercises to comfort your eyes are:
Near focus, then far focus
Hold a finger a few in front of your eye, and focus on the finger. Then move your finger away from your eye. Always focus on your finger. When the finger is at the maximum distance, stare away for some seconds. Then focus on your finger and bring it back near your eye. Don’t lose focus. When your finger is to the nearest of your eye, stare away. Repeat three to five times.
Different focus points
Hold your finger in front of your face. Focus on it for some seconds. Then focus to a distant point, behind the finger. Focus on that point for the same amount of time. Then focus on the finger again. Repeat several times.
The popular 20-20-20 rule
Maybe the 20-20-20 rule is the most useful eye exercise we should do many times a day, to relief and rest our eyes.
Our world dictates to stare at a near object for hours. How many hours a day do you stare your smartphone, your computer or your television?
The 20-20-20 rule is simple. Just every 20 minutes, stare an object, that’s 20 feet away, for at least 20 seconds.
There is no need to literally stare something in exactly 20 minutes at exactly 20 feet. Just every now and then stare an object that’s not the screen of the computer. Focus on an object out of the office window, a tree for instance. Do it several times a day.
Lazy eye exercises
- Cover your healthy eye.
- 1 or 2 feet distance from the screen.
- The point of the exercise is to make your eye move around the eye socket.
Do eye exercises improve vision?
So if you want to start these eye exercises you should ask yourself if any eye exercise can change the:
- shape of the eyeball (myopia or short-sightedness, Hyperopia- Long-Sightedness) or
- shape of the cornea (Astigmatism) or
- eye surface
- eye’s elasticity (presbyopia)
At most common eye exercises you move your eye muscles:
- circular, or
- change your point of focus to different distances
Some eye improvement programs suggest to ditch the glasses or contact lens. Please consider a professional eye doctor before embracing such a program. Consider driving without your glasses. You can put great dangers to yourself and others.
Any type of eye therapy which promises to see without glasses shouldn’t consider scientific. Always seek an eye doctor advice. There’s a chance to improve your eyesight but there are no scientific data to show that someone can improve so dramatically his vision, as to see without glasses.
Vision therapy exercises
Vision therapy shouldn’t be confused with eye exercises. Vision therapy is prescribed by some eye doctors. Vision therapy can help with certain eye problems as amblyopia and strabismus. Also, vision therapy is used to improve vision for athletes.
Usually, vision therapy exercises are performed under the supervision of an eye doctor. Mainly, vision therapy exercises aim to strengthen the eye muscles
Sports Vision Training
Sports vision training isn’t vision therapy. Sports vision training exercises are designed to enhance a person’s visual skills for a specific sport rather than to correct a vision problem. Many professional athletes have followed sports vision training programs to achieve better results in their sport. As these technics are very sophisticated, an eye health professional advice is preferred.
Improve eyesight through diet
Last, but not least, eyesight can be improved through a healthy whole food plant-based diet. Eyesight can be protected by carotenoids. Carotenoids are abundant in vegetables and fruits. Choose the most colorful veggies to have the best results.
Also, avoiding heavily processed foods, you avoid sugar, salt, and fats. So, you can drop your high blood pressure.
Certainly, the best food supplement for eye health is moringa powder. Moringa powder is the richest sources of beta-carotene, lutein, and zeaxanthin. All powerful carotenoids. Only a few foods are good sources of carotenoids. Moreover, moringa powder is rich in antioxidants. Especially in vitamin C and vitamin E.
