eventually cleared up.

It took a few months but my GP has gotten me linked up with an optometrist who apparently works with PCS patients, supposedly she does a specific hour-long evaluation so i'd have to imagine that will be pretty thorough. Mine's in a few weeks so I'll report back- reading feels generally imprecise and labored, especially in weird lighting conditions so hopefully she has some kind of therapy to help restore function in that regard.
