I have a male character, 22 years-old, who is punched in his right eye by someone wearing a ring.
Could a ring, similar in shape/details/etc. to this cause enough damage (such as a retinal detachment) resulting in complete blindness in one eye?
What effects would a retinal detachment have on eye movements?
I Googled things like ‘blunt eye trauma', 'effects of retinal detachments' and 'causes of blindness'.
