If anyone else can think of anything else they'd like to see tried (no,
not in *my* plane) please post it here.

This isn't meant to be a scientific experiment or to become information
used instead of any government research or guidelines. OK?

How about:
1. Acquire a standard optometrist eye chart.
[A television resolution chart would be a good substitute]
2. Before each exposure, determine visual acuity.
3. After each exposure, repeat acuity test
4. Start at a lower exposure duration and work up.
[This may require performing the test(s) on separate nights]
5. Do the whole thing during the day, facing away from the sun.
6. Chart your work

Hmmm, before step 1, check your medical insurance and have an
optometrist or opthomalogist do a retinal scan, before and after.
