My double vision has improved. U can write normal, though I won’t complain if u write in a larger size! My iPad blows up font, my computer can speak what’s written, I have a large moniter (so small font looks big) & since my eye muscles seem stronger (probably ffrom daily use of my iPad mini), while I still have double vision, I have “gotten used to it”, & can usually read smaller font—as small as size 11, if my contacts aren’t yucky!
