Visual Therapy At Sai Research Institute
Vision therapy is a doctor-supervised, non-surgical and customized program of visual activities
designed to correct certain vision problems and/or improve visual skills.
Unlike eyeglasses and contact lenses, which simply compensate for vision problems, or eye
surgery that alters the anatomy of the eye or surrounding muscles, vision therapy aims to
"teach" the visual system to correct itself.
Vision therapy is like physical therapy for the visual system, including the eyes
and the parts of the brain that control vision.
Vision therapy can include the use of lenses, prisms, filters and computer-assisted visual activities.
Other devices, such as balance boards, metronomes and non-computerized visual instruments also can
play an important role in a customized vision therapy program.
Problems vision therapy can correct
Vision therapy can relieves symptoms and improve outcomes
for a variety of vision problems, including:-
- 1. Amblyopia : Also called "lazy eye," amblyopia is a vision development problem where
an eye fails to attain normal visual acuity, usually due to strabismus or other
problems of eye teaming.
- 2. Strabismus : The success of vision therapy for strabismus depends on the direction,
magnitude and frequency of the eye turn. Vision therapy has been proven effective for
treating an intermittent form of strabismus called convergence insufficiency, which is
an inability to keep the eyes properly aligned when reading despite good eye alignment
when looking at distant objects.
- 3. Other binocular vision problems : Subtle eye alignment problems called phorias that may
not produce a visible eye turn but still can cause eye strain and eye fatigue when reading
also can be minimized or corrected with vision therapy.
- 4. Eye movement disorders : Studies have shown vision therapy can improve the accuracy
of eye movements used during reading and other close-up work.
- 5. Accommodative (focusing) disorders : Other research shows near-far focusing skills
can be improved with vision training.
- 6. Other problems : Other vision problems for which vision therapy may be effective include
visual-perceptual disorders, vision problems associated with developmental disabilities and
vision problems associated with acquired brain injury (such as from a stroke)
