I covered up one lense of my glasses with electrical tape when my double vision first appeared, got lots of comments about that one! I then graduated to painting over one lense with black paint. My right eye is the worst tho so I always covered that one.
Check with the eyeglass makeres, they have clipon things to occlude one eye (cover it up). I couldn’t use the eye patches at all since my proptosis was so bad it was very uncomfortable. My eyes even hit on sunglass lenses.
If someone wants this clip-on occluder I have to cover up one eye, e-mail me and I’ll send it to the first one!
