Low vision depicts various conditions whereby vision cannot be sufficiently improved by the use of ordinary spectacles, contact lenses, medicine or surgery. A more specialised visual examination is performed which differs from the routine eye examination. This examination provides us with additional information enabling us to prescribe special low vision devices necessary for the patient to "see".
The areas of vision loss cannot be regained. We thus strive to prescribe visual aids which employ the principle of magnification in order to assist patients perform tasks that they were previously unable to do. These devices can take the form of spectacles, microscopes, reading lenses, hand or stand magnifiers or various telescopes depending on the task to be accomplished. Central and/or peripheral vision may be affected from many eye disorders including macular degeneration, diabetes, glaucoma and various injuries to the eye or to a portion of the brain involved in various aspects of sight.
