It's important to keep in mind that most people with open-angle glaucoma, the most common type, have no symptoms until they have lost a significant amount of vision.
The condition can be prevented, but once vision is lost, it is irreversible. That is why it's very important to get regular exams with an eye doctor, particularly if there is a family history of glaucoma.
Symptoms of glaucoma vary, depending on its type.
Although scientific proof of effectiveness is lacking, there are doctors who may recommend eye exercises for eyestrain, blurred vision, headaches, increased sensitivity to bright light, tired eyes, or difficulty sustaining attention. Eye exercises will not help people who have nearsightedness, dyslexia, or excessive blinking or squinting of the eyes. Also, these exercises are usually not effective for paralysis of an eye muscle, eye muscle spasms, or eyesight problems that do not cause the symptoms mentioned above.
With conditions such as amblyopia (decreased vision in an eye due to preferential use of the other eye which develops in childhood), eye exercises may be helpful when prescribed in early childhood. Providing proper eyeglasses, if needed, is the first step. Amblyopia is then treated by patching or using eyedrops to block or blur the good eye. Vision therapy exercises can also force the brain to see through the amblyopic eye, which helps to restore vision.
What Do Eye Exercises Involve?
Eye exercises are designed to strengthen the eye muscles, improve focusing, eye movements, and stimulate the vision center of the brain. Through a series of progressive therapeutic exercises, you can be instructed on how to control your eye muscles and to see properly.
The eye exercises prescribed are usually unique to the patient and vary depending on the patient's age and other existing eye problems. Examples of different types of eye exercises include changing focus of both eyes from near to far and back to near, switching as each distance becomes clear; covering one eye with one hand and looking at different objects continuously instead of staring at just one object; concentrating the eye on a solitary object; or having the eye follow a pattern in order to build vision muscles.
