tfouto Yes, all of the new ones if I use them for too long without my glasses, which separate equally the work needed between my two eyes, and if theyre too bright compared to surrounding area, meaning theres no peripheral points to fixate my gaze upon. Also if I have a really bad day, I feel its not completely ok and need to take breaks. Ive been told it might not be fixed completely, but the difference now is huge and Im willing to go on with some alternative and more specific exercises once the main therapy course is done.
diop yes, fusion is the crucial word. The new tech probably does not allow for as easy a fusion as the old one.
tsb Maybe because as you have noticed, the new tech makes somewhat of a 3d picture, even of a very little depth, and that creates different inputs for each eye (as 3d is essentialy made only by having different input in each eye). People with heterophoria and related issues have therefore trouble making the image sharp and connected for longer periods of time.
