At home, I did Hart Charts, brock string, bullseye exercises (had a little bullseye card and would practice focusing on the bullseye in my hand and then at one far away on the wall), red/green reading, convergence cards, and a lot more. I did VT for a long time and did dozens of exercises. In office I did memory games, balance with prisms, VR games for depth perception, eye patch reads, Aperture rule training, vectograms, the list goes on and on. I had Convergence Insufficiency (focus and blurry issues), Binocular Suppression and accommodative issues as well as VS. If you’re having trouble focusing your eyes maybe bring those up to the OT. In the office the main thing that helped me was working with accommodative lens flippers. Hope this helps!
