was in market to get lenses for quest 3 and tried to get quotes from a few places for lenses with prism. all treated this normally bar vr rock which tried to convince me of the following.
‘The lenses used in virtual reality typically do not require prisms. While some of our customers have prescriptions with prism, they do not specifically request the inclusion of prism in the lenses. They can use these lenses with such prescriptions without any issues.’
This is of course objectively not true . prism is used for failed convergence if i dont have prism on my lenses i see two of everything.
