Low vision should not be confused with blindness. People with low vision have some useful vision which can often be improved with low vision aids. Visual impairment may be mild or severe. Low vision usually results in reduced central or reading vision, but may also result from decreased side (peripheral) vision, a loss of color vision, or an inability to properly adjust to light, contrast or glare.
Many aids are available to help people with low vision including magnifiers, reading glasses and closed-circuit television devices.
