TEST 4 - ETDRS Table
The logarithmic table allows to study in a proportionally uniform way all the visual acuities. For this reason it is particularly useful to analyze with precision the low visual acuities in patients affected by maculopathies, neuropathies or alteration of the optical means.
A rough idea of your visual acuity can be obtained by taking a reading on a bright monitor, about 2 meters away.
