There is no evidence that fish go blind being in a round bowl. Optical conditions are different looking from water into air is different than visa vera. Those that have a swimming pools can try this experiment.
If you have a large clear plastic container (larger the better) that will fit your head with goggles/dive mask on. Go into the shallow end and submerge the container. Stick your head in and pop your head out with the container on out of the water so that the opening of the container doesn't come out of the water. That's the the fish will see while in the aquarium. Try it with rectangular/square, cylindrical and spherical shapes.
NOTE: if you hurt yourself, I am not liable for this suggestion. Please take the proper precautions.
For fish suggestions and care, join a fish forum or club for advise and guidance. Equipment, experiences, products and techniques vary.
