One of my eyes is always red, why and what do I do?

As a teenager I had uneven eyes so I used this eyelid tape thats not uncommon in the Asian community. I was pretty desperate so I used it pretty much every day for a couple of months. It irritated my right eye(the one I put it on) so much, but I refused to stop wearing it. Eventually, maybe 8 months ago, I realized I was being an idiot and stopped wearing the tape. However, my eye is still red. I ve gotten pink eye twice and a chalazion since then, and I really don t know what to do. Can someone explain why this is happening and how to fix it? Btw, I think I might ve developed an allergic reaction to the adhesive on the tape I used on my eyelid, which most likely explains the redness I experienced while I wore it. However, I ve stopped wearing it and the redness continues. Thanks to anyone who answers.
