• Would prism glasses cause a normal sighted person to see double vision?


    Question:

    I have double vision and have long been frustrated by not being able to show people what I see. Because prisms are used to correct/stabilize double vision, would it be true they can also be used to induce double vision in normally sighted people? I see a lot of those low vision simulators online, but no one has a double vision one.


    Answer:

    Yes, if you place an appropriate prism in front of one eye of a patient with no misalignment you can create double vision.
