I have a character that has strabismus (often called lazy eye) that was never corrected. The setting is fantasy medieval so we have situations from sword fighting to crafts, labor, riding and running. Could anyone give me some hints on how this would affect him in his day to day life? I would appreciate the input of someone who is more knowledgeable about the condition than I am.
How would it affect his ability to fight with a sword? How about shooting a slingshot, would that even be possible for him? Would strabismus affect his fine motor skills like fiddly craft type stuff or even learning to write? What about using a hammer?
I researched the condition in general but I mostly came up with information on how it is corrected. One slingshot forum gave me some hints that it would likely be very difficult to impossible without accurate depth perception. But I don't know if aiming that type of weapon could still work with monocular cues or if you truly need the binocular cues to hit a human-sized target. Anyone have experience shooting a sling shot one-eyed? My gut tells me that binocular depth perception is more important for things that are close by, like with sword fighting. Is that correct? But how well would he then do with things that are very close like sewing or whittling something?
I would appreciate all information you can give me on this. Thank you!
