Do you know a chart that is made to asses directional visual acuity?
I thought about making one, but not sure how…
Initial thought was to make a chart with two lines in each row like so:
where the spacing between the lines should be the resolution for every 20/xx.
For each eye:
You’ll have one chart that is aligned to your axis,
and another chart that is perpendicular to your axis.
The test would be to check where you stop distinguishing between the two lines.
