Along with the severe head trauma came fourth nerve palsy, a stretched muscle in the back of my eye giving me double vision. This is most annoying and made it hard to go down stairs or pass a ball reliably, depth perception is useful. It's healing and now only affects me when I'm looking down or slouching backwards. Alas the head trauma means I slouch a lot. The NHS covered over a lense of my glasses with tape which worked well but I don't wear my glasses most of the time. You can buy plenty of cheap eye patches from costume shops with skull and cross bones on them but they look daft and are uncomfortable to wear for any period of time. The doctors at the eye hospital didn't know where to get decent ones. The only eye patches I've found which are comphy to wear all day are made not for people with wonky eyes but... American Medieval Recreation Societies. BirchCreekLeather on Etsy make good ones. They're clearly missing out a market by marketing them only to costume wearing Americans and not to people who actually need an eye patch.
