This change was made as newer studies showed that best-corrected vision overlooks a larger proportion of the population who has visual impairment due to uncorrected refractive errors, and/or lack of access to medical or surgical treatment.Distance vision impairment:

Category 0: No or mild visual impairment –presenting visual acuity better than 6/18
Category 1: Moderate visual impairment –presenting visual acuity worse than 6/18 and better than 6/60
Category 2: Severe visual impairment –presenting visual acuity worse than 6/60 and better than 3/60
Category 3: Blindness –presenting visual acuity worse than 3/60 and better than 1/60
Category 4: Blindness—presenting visual acuity worse than 1/60 with light perception
Category 5: Blindness—irreversible blindness with no light perceptionNear vision impairment:

Near visual acuity worse than N6 or M.08 at 40 cm. United Kingdom
Severely sight impaired

Defined as having central visual acuity of less than 3/60 with normal fields of vision, or gross visual field restriction. Unable to see at 3 metres (10 ft) what the normally sighted person sees at 60 metres (200 ft).Sight impaired

Able to see at 3 metres (10 ft), but not at 6 metres (20 ft), what the normally sighted person sees at 60 metres (200 ft)
Less severe visual impairment is not captured by registration data, and its prevalence is difficult to quantifyLow vision

A visual acuity of less than 6/18 but greater than 3/60. Not eligible to drive and may have difficulty recognising faces across a street, watching television, or choosing clean, unstained, co-ordinated clothing.In the UK, the Certificate of Vision Impairment (CVI) is used to certify patients as severely sight impaired or sight impaired.
