I wonder if they can actually do this meditation as well and experience the
effects of it after, if not than I don't know how they could unless there is
another way?

And can people who has lazy eye can they also do the OEM experience the
meditation effects as well?

As well as other people who have any eye disorders that prevents them from doing
OEM, than I guess they need to get another way to achieve enlightment in another
way possible!
