Hi, I suffered an allergic reaction using magnex forte injection due to which there was a headache for a couple of days, it went off but since then there is a re-occurrence of headache and eyes becoming red usually so i went for a eye check up and they prescribed me spherical glasses (Long Distance) for L eye 0.5 right eye 0.75 My question is - 1. Is it necessary to use the glasses all the time? 2. Is it going to be a long term problem? Thanks for your help in advance.
