I was wondering that if wearing a wrong prescription contact lens with an error of -0.5 is bad for my eye or not. I was in a trip last week and I broke my right eye contact lens by mistake. I had no access to any doctors there so I just used my spare left eye contact lens which is -2.25 (my right eye is -1.75).After a week I don't feel any discomfort and even I sensed an improved vision, so I'm just asking to see if there's anything wrong or not
