Today I swapped out the filters for the magenta Alpha Delta filters. They were much brighter than I remembered them the previous time around. I slept really well last night, and there does seem to be some difference from the previous night; the images are able to get closer to one another before the fixing image gets blurry. This is a positive indicator of progress.
Also, the saccades appear to be their best yet. Stereopsis may be very near.
