Understanding the role of visual training and eye exercise:
The practice of exercising the eyes in order to overcome and even avoid certain visual disorders especially those related to binocular vision is defined as visual training. In order to relieve the stress associated with long periods of focused vision, visual training and eye exercise is an excellent option. For centuries, visual training has been used to treat disorders related to the eyes. In the early days, such training was applied to infants, however over time; visual training became a part of the therapy used and suggested by ophthalmologists. A branch of ophthalmology was developed that included the practice of visual training and eye-exercise known as Orthoptics. This article details the effectiveness of visual training. Following are some of the conditions where visual training and eye-exercise have been found effective.
1. Visual training and eye exercises for Eye-Disorders:
1.1.Convergence Disorder/Strabismus: In this condition the eyes are not properly aligned. In strabismus, visual training is most effective among both adults and children. Pencil push up therapy is used to manage this disorder. In this regimen, a pencil is held in front of the eye at arm’s length, with the pencil perpendicular to the floorand then slowly drawn towards the nose with the exerciser focusing on this moving pencil When a double image is seen, the pencil must be drawn away from the nose again. This process is repeated several times in each session. This exercise conditions and strengthens the eye muscles.
1.2.Amblyopia or lazy eyes: When one eye is dominant than the other, the condition is called amblyopia. Treatment of this disease requires patching of the dominant eye to encourage the use ofthe lazy-eye. Evidences have suggested that placing the patch for six hours/day improves the vision of the amblyopic eye. Gradual reduction in the length of treatment before complete cessation can help to reduce the risk of amblyopia. With the brain being compelled to use the weaker/effected eye, the brain gets conditioned to accept the image from the eye and gradually the ailment is cured.
1.3.Optic or Brain nerve injury: Improvement in the field of vision is observed in patients who have retained residual vision after the brain or optic nerve injury. Some of the common visual training and eye exercises to manage these conditions areperformed under the guidance of an ophthalmologist including lens fixation and prism fixation wherein a series of lenses and prisms are arranged in a specific orientation respectively to train the eyes to adjust in the different visual fields.
2. Visual Training and Eye exercises for temporary eye irritation:
Visual training and Eye exercises can reduce temporary eye-irritations, which can be induced by either strain caused by focused vision; mostly observed in computer users. This populous is more prone to developing visual disorders due to longduration of focusing on computer screens; this problem is also being noticed in the younger generationdue to long hours of playing video games.
2.1.Eye movement:One must perform eye exercises regularly to ensure the full range of vision. The simplestvisual training and eye exercise regimen for everyone is as follows: Sit in an upright position while looking forward; Now without moving your head, look up and down alternatively repeating the process for both right and lefteye as well. This exercise must be repeated several times in a day or as and when you feel strain on the eyes.
2.2.Visual rest: Resting the eyes is very important for everyone, especially for a person who work on computers for long periods of time. This can be done by simply focusing on distant objects (which are located at-least at a distance of three meters) periodically.
2.3.“20/20/20” rule: This is a unique and fun method of resting the eyes. After every 20 minutes of computer use, one must look something which is located at 20 feet away for 20 seconds.
