I'm 18 years old and i got prescription glasses 3 years ago....and 2 months ago i started having some weird feelings in my eyes...my left eye ( the biggest problem ) feels okay at the start of the day but i noticed that around 21 pm or so it starts to get red and i can barely use my phone at night....it starts to hurt so bad that the left side of my head hurts too and i went to my doctor i got now glasses and he said that i have an eye allergie in my left eye...he gave me 2 eye drops i used them for like 3 weeks and i still had the same problem same pain feeling + i noticed that the vision in my left eye with the glasses is blurry...very blurry that i see double images and i felt like they my made my eye worse that whenever i wear them i get the same eye and head pain and everything goes away when i take them off...so i went to another doctor and he said that the medecines that the other doctor gave me weren't doing much and that the glasses had a mistake done while making them...i got a new medicineand new glasses and i used the medicinefor a month ( just finished the last eye drops yesterday ) and one of the medicine i was sure that it gave me dry eyes and it was kinda painful and the glasses are doing fine after a month of using them but these 2 days after finishing the medicine my eye still hurts and the back of my head too i have no problems of vision just the pain for no reason ! and the pain kinda goes away when i take them off amd relax my eyes....also i use my phone a lot so that can be a problem
