If Im tired I do too. I noticed that during the therapy and with the prismatic glasses, it was so much better that I had a comparison to how bad it actually was before. These days if my eyes are rested from new tech, I can read printed text well even without the glasses, but my eyes get tired after some time quite a lot.
You have to consider that when you have binocular vision dysfunction, one of your eyes is usually suppressed for most of the time. When you relearn to use both eyes, everything changes and your system will fight that previous slip to suppression creating new issues if you try to get back old habits, read without glasses that you or I very obviously need, etc.
The suppression is easily tested. When you read text, try to close one of your eyes (or the other) and check if all of a sudden that eye has to focus and find the text. If that happens, that eye was suppressed all of the time of the reading.
My theory with the flicker is that it doesnt allow for eye suppression - the flicker wakes up your eyes all the time now.
