Vision requires us to separate the foreground from the background, to recognize objects that are viewed from an incredible range of spatial orientation, and to accurately interpret spatial cues or risk walking into doors rather than through them. Visual Perception — The Eye Vision begins in the eye which receives the inputs, in the form of light, and finished in the brain which interprets those inputs and gives us the information we need from the data we receive. The components of the eye are pictured below. Copyright terms and licence:
The act of perceiving and interpreting visual information with the eyes, mind, and body.

For the complete scoop, see the illustrated page on Stereo Vision! A visual defect in which the two eyes fail to work together as a coordinated team resulting in a partial or total loss of binocular depth perception and stereoscopic vision. Amblyopia and strabismus are the most commonly known types of binocular vision disabilities.
To find out more about these visual conditions, see What is a binocular vision impairment? The result is often a loss of stereoscopic vision and binocular depth perception. Vision therapy can benefit this condition, but early detection is very important.
For many years, it was thought that amblyopia lazy eye was only amenable to treatment during the "critical period". This is the period up to age seven or eight years. Current research has conclusively demonstrated that effective treatment can take place at any age, but the length of the treatment period increases dramatically the longer the condition has existed prior to treatment.
Research has also demonstrated that patients with amblyopia are more likely to sustain injuries resulting in the loss of their good eye than individuals with two good eyes. There are many reasons that early childhood eye examinations are essential.
It is a visual defect in which the two eyes point in different directions. One eye may turn either in, out, up, or down while the other eye aims straight ahead.
Due to this condition, both eyes do not always aim simultaneously at the same object. This results in a partial or total loss of stereo vision and binocular depth perception. The eye turns may be visible at all times or may come and go. In some cases, the eye misalignments are not obvious to the untrained observer.
To learn more about the treatment of strabismus, go to children-special-needs. Vision therapy can involve a variety of procedures to correct neurophysiological or neurosensory visual dysfunctions.
See What is Vision Therapy? The eye muscle training techniques of orthoptics are included within vision therapy.
Orthoptics specifically treat eye teaming skills and visual acuity and do not treat other visual dysfunctions which are addressed by vision therapy procedures.
Orthoptics first became popular in Europe in the s. Orthoptics are still practiced by a small percentage of optometrists, ophthalmologists and orthoptic therapists.
Learn more about orthoptics at Frequently Asked Questions for more information. In most states, optometrists are licensed to examine visual health, prescribe glasses and contact lenses, fit special devices for vision-impaired individuals, treat some eye diseases, prescribe some drugs and perform vision therapy.
See FAQs for more information. A doctor of medicine M.How Vision Works. Solving the problem of converting light into ideas, of visually understanding features and objects in the world, is a complex task far beyond the abilities of the world's most powerful computers. Visual perception begins as soon as the eye focuses light onto the retina, where it is absorbed by a layer of photoreceptor.
