Amblyopia, also called lazy eye, is a disorder of sight in which the brain fails to fully process input from one eye and over time favors the other eye. [1] It results in decreased vision in an eye that typically appears normal in other aspects. [1] Amblyopia is the most common cause of decreased vision in a single eye among children and ...

A distant object is defined as an object located beyond 6 meters (20 feet) from the eye. [citation needed] When an object is located close to the eye, the rays of light from this object no longer approach the eye parallel to each other. Consequently, the eye must increase its refractive power to bring those rays of light together on the retina.
The room or location of the test should be brightly illuminated and the patient's optical correction (e.g. glasses, bifocals, multifocals, contact lens) is required to be worn. In the event that correction cannot be worn due to the obstruction of vision through the eye piece, lenses may be placed within the lens holder before each eye.
It has only recently [when?] become possible to measure the aberrations of the eye and with the advent of refractive surgery it might be possible to correct certain types of irregular astigmatism. The appearance of visual complaints such as halos , glare and monocular diplopia after corneal refractive surgery has long been correlated with the ...
A complex approach to non-surgical management of strabismus (wandering eye), amblyopia (lazy eye) and eye movement disorders may include a variety of vision therapy methods, primarily directed at the abnormal retinal correspondence management such as eye occlusion with an eye patch, binocular vision training using a haploscope and many others ...
