Yes you would think they would have cleared up by now...but we hear on the news all the time about people having bad reactions to some med or whatever...and they don't get better...

And yes you COULD be allergic to any number of things in the eye drops or even the meds. If you read the lists of ingrentance on these things maybe you could find something similar. My son used to be allergic to dyes in foods. Well try figuring that out! lol. He could drink some healthy juice...have some ceral or some chips and over the counter meds and so on and have a reaction to all of these things. They seem all very unrelated...until you read the ingretance and see all of these things have something like red dye 40 in them...INLCUDING the vitamines...including over the counter meds...EVEN including rx meds! Especially that stupid bubble gum flavored antiboic made for little kids...TONS of red dye 40 in it. Even PILLS have dyes in them. grrrrrr. They even put red and blue dyes in grape juice...as if it NEEDS to be more purple???
Stuff for kids is even worse...oh and they even put dyes in pet food? Like the dog or cat can see the colors and think....gee that looks tastiy with all the orange and blues and browns...I think I will eat it. WEll yea try cleaning those DYES up off the carpet after they throw up that lovely colorful dinner...grrrrrr.
One day I am going to email all these companies that put dyes in their whatever and gripe them out! lol.
You could have had a very serious allergic recation to the lenses...esepcially if they made you feel funny too...or the drops that went with them and it could just take awhile for it to get out of your system. I bet if you searched it out you can find their side affect list and see how many people have had reactions like yours.

Then I would contact them and ask how it should be treated.
