Low Vision

The clinic aims to provide, the best possible management, for persons with low vision.

A person can be diagnosed with low vision in the following situations:

  • Best corrected visual acuity of 6/18 or less and/or field of vision of 10 degree or less from point of fixation.
  • People who are unable to see objects (e.g. a person’s face) beyond maximum of 3m i.e., 10 feet distance (with their spectacle correction) and/or people those who have side vision difficulty are said to have low vision.
  • When ordinary eye glasses, contact lenses or intraocular lens implants cannot provide sharp vision, an individual is said to have low vision.
  • Although reduced central or reading vision is common, low vision may also result from decreased side or (peripheral) vision, a reduction or loss of clarity of vision, or the inability of the eye to properly adjust to light or glare.
