What is Low vision ?

Low vision is caused by a variety of conditions involving people over 65

Dr . Chris Schell , Barrie optometrist provides Low Vision diagnosis and treatment

Low vision can occur at any age, but by far the greatest number of people who are partially sighted are the elderly. Low vision is most often due to a change in central vision. Occasionally it is associated with loss of side (peripheral) vision when it is close to centre. In a few cases it is associated with loss of colour vision or difficulty adapting to changes in brightness within the field of vision.
A variety of disorders that affect the eye and the visual system may cause low vision. Birth defects, injuries, certain diseases of the body and aging all may lead to loss of sight. Most commonly, it is due to scarring because of deterioration of the central part of the retina (the light-sensitive tissue that lines the back of the eye). Loss of sight may also result from other conditions, such as cataract and glaucoma, or from damage to the optic nerve, which carries visual images to the brain.Since there are many diseases and conditions that can result in low vision, it is important to have a comprehensive eye examination by an optometrist. . Once the cause of low vision is identified, Dr . Schell may suggest low-vision aids such as magnifying glasses or special, strong reading glasses. There are also many other helpful devices that are not optical devices including large-print books, magazines, newspapers, playing cards and telephone dials, and large-character calculators. Increased lighting that is properly positioned is essential. Tinted lenses are sometimes used to reduce glare from bright sunlight. Electronic aids such as closed-circuit television systems with built-in magnification and computerized reading devices are also useful in some circumstances.
