File talk:ETDRS Chart R.svg
Out of scale[edit]
The measurements are not in scale compared to a standard snellen chart, but much smaller. There is not a scale reference (i.e. "1 cm" "1 inch" lines). Even the conversion of units is wrong (between meters and feet) i.e. there are not 5 feets to a meter... Adolphitus (talk) 17:36, 30 July 2023 (UTC)
