A person with low vision is one who has impairment of visual functioning even after: treatment, for example an operation and/or standard refractive correction (has been given glasses or lenses) and has a visual acuity of less than 6/18 to light perception, or a visual field of less than 10° from the point of fixation (i.e. 20° across) but who uses, or is potentially able to use, vision for the planning and/or execution (doing it!) of a task.
It is important to note that if a person’s vision improves with contact lenses or spectacles to better than 6/18 may not be considered to have low vision. However, low vision criteria only follows when the best-corrected visual acuity is less than 6/18.
