I have been wearing contacts for 9 years and have always worn the same brand (Aquatech 2 with Opti Free solution). About a month ago I woke up and my left eye was very red and thought it might be irritated so I wore my glasses for a few days and allowed them to clear up. I opened a new pair of contacts and used them for two days with no problems. When I woke up the third day my eye was bright red again. I have been wearing glasses and occasionally trying to go back to contacts but I keep having the same problem. Could this be from the solution? Also, this began with a new box of contacts and in less than a month I have used a 3 month supply of contacts from continuously throwing them away. Is it possible something is different about this box is "bad"? I'm ordering new ones since I'm almost out now, and also switched to clearcare solutions. Im hoping this works but any other advice would be appreciated, I hate wearing glasses all the time!
