The World Health Organization (WHO) defines low vision as visual acuity of less than 6/18 and equal to or better than 3/60 in the better eye with best correction. In other words, when ordinary eyeglasses, intraocular lenses implant or contact lenses cannot provide sharp or clear vision, a person has low vision.

The American Optometric Association divides low vision into two categories:

  • Partially sighted: visual acuity between 20/70 and 20/200 with conventional prescription lenses.
  • Legally blind: visual acuity no better than 20/200 with conventional correction and/or a restricted field of vision less than 20 degrees wide.

The ratio measurement of vision describes visual acuity, or sharpness of vision, at 20 feet from an object. For example, having 20/70 vision means that you must be at 20 feet to see what a person with normal vision can see at 70 feet.

Common types of Low Vision

  • Loss of peripheral vision: the inability to see anything on either side, above or below eye level with central vision intact.
  • Loss of central vision: a blind spot in the center of the field of vision.
  • Night blindness: the inability to see in poorly lit areas.
  • Blurred or hazy vision: lack of sharpness of vision resulting in the inability to see fine details.

At The NAB Workshop for the Blind, we believe that awareness and timely treatment of eyes can save individual from complete blindness. Keeping this in mind the Kantaben & Varjivandas Saraiya Low Vision Centre (LVC) was opened on 19th January 1984.

The center is dedicated to treating people with low vision and has been providing various aids to improve and enhance residual vision at the retina level. The center also provides routine eye checkup along with refractive error, Intraocular pressure slit lamp examination and Fundoscopy.
