Most test charts that use Snellen methodology do not have lines that measure visual
acuity between 20/100 and 20/200. However, some newer test charts have lines that
measure visual acuity between 20/100 and 20/200, such as the Bailey-Lovie and ETDRS.
If visual acuity is measured with one of these newer charts, and the claimant cannot
read any of the letters on the 20/100 line, we will consider that the claimant has
statutory blindness based on a visual acuity of 20/200 or less. For example, if best-corrected
visual acuity for distance in the better eye is 20/160 using an ETDRS chart, we will
find the claimant has statutory blindness.
A claimant does not have statutory blindness if he or she can read at least one letter
on the 20/100 line. For example, the best-corrected visual acuity in the better eye
is 20/125+1 using an ETDRS chart. The claimant does not have statutory blindness because
he or she is able to read one letter on the 20/100 line.
