reaganry No and I would not. It needs to be precisely crafted for your own specific case. Otherwise it might do more harm than good.
tsb Pretty much yes. I have two more months of visual therapy left, but I have almost no symptoms by now. I can use my iphone 7 all day (in the past I had migraine after 10 mins). I was working on some friends 2018 macbooks and hopefully will be able to use one for regular everyday work soon. I need to wear glasses as one eye is weaker therefore the heterophoria is more pronounced (system prefers the sharper eye). You need to see a real and good optometrist.
Also if you do training, you have to have patience and discipline. Ive been told that by training as much as I did, I even overcompensated the problem by another 20 points, which was supposedly never seen before and is a useful reserve.
