It is well-known that certain eye conditions result not only in personal discomfort but also in difficulties with reading. Impaired vision can, of course, cause reading problems, since it limits differentiation of details. However, when people of limited sight manage to read with or without visual aids, they usually read normally, although perhaps slower than those with normal vision. Eye characteristics that result in more specific disturbances of the reading processes include especially latent strabismus, that is, a tendency toward squinting, and insufficient convergence, which involves impaired ability to fixate both eyes on the same target at near point.
