A person will not be classified as legally blind if they can read even one letter on the 20/100 line. It can also be complete, in which case there is no perception of light. So for example, if the person's best-corrected visual acuity for distance in the better eye was determined to be 20/160 using the Bailey-Lovie or ETDRS chart, they would now be classified as legally blind. This change was made because the original acuity requirement was based on Snellen projection acuity which did not have any acuity measurements between 20/100 to 20/200. ![]() Legal blindness is not a medical definition but a legal definition. Four leading causes of legal blindness in the UK are age-related macular degeneration (AMD or ARMD), cataracts, diabetic retinopathy and glaucoma. Under the new updates to the law in 2007, if a person's visual acuity is measured with one of the newer charts like the Bailey-Lovie or the Early Treatment Diabetic Retinopathy Study (ETDRS), and they cannot read any of the letters on the 20/100 line, they will be considered as legally blind.

The definition of legally blind vision is when someone has 20/200 or worse vision on a standard vision chart in their better eye, or when they have less than 20 of peripheral vision on a visual field test. ![]() Newer test charts, such as the Bailey-Lovie or the Early Treatment Diabetic Retinopathy Study (ETDRS), do have lines that measure visual acuity between 20/100 and 20/200. For visual acuity testing, the criteria changed because most test charts that use Snellen methodology do not have lines that measure visual acuity between 20/100 and 20/200.
