In order to see a clear image, the eye must focus rays of light on to the light-sensing part of the eye - the retina, which is located in the back of the eye. This focusing - called refraction - is performed mainly by the cornea and the lens , which are located at the front of the eye, the anterior segment .

Convergence insufficiency is characterized by one or more of the following diagnostic findings: patient symptoms, high exophoria at near ...
Vision therapy ( VT ), or behavioral optometry, is an umbrella term for alternative medicine treatments using eye exercises, based around the pseudoscientific claim that vision problems are the true underlying cause of learning difficulties, particularly in children. [1]
Irlen syndrome (or scotopic sensitivity syndrome) is a hypothetical medical condition of disordered visual processing which, it is proposed, can be treated by wearing colored lenses. The ideas of Irlen syndrome are pseudoscientific and not supported by scientific evidence, [1] [2] [3] and its treatment has been described as a health fraud ...
