Hi, martin, I went to my optometrist for a checkup after a year of glasses (astigmatism 0.5 + postural prism) and by retesting my esophoria up close it was almost gone while the esophoria got worse from afar (one year ago it was the opposite).
I also discovered that I have a new problem (which you have too if I understand correctly), accommodation insufficiency on my left eye. I think this is why I have a burning sensation even with "good" devices for 2/3 months.
This week I start the visual training with the scope to fix the accommodation insufficiency.
