This has been going on for a long time, i tear up way too much at random times, and when i dont it feels like there is an onion near by, it slightly burns, not badly though.i do wear contact lenses, i use them accordingly and nothing like this ever happened to me, i clean them every morning too, i dont think anything is wrong with the solution i've been using it for a year now
