I'm happy to answer your question today.
Thanks picture. That is called a pinguecula.
Does this make sense to you?
Stop the visine....that will just irritate things. Use natural tears to soothe it. These things get red from time to time and it is of no consequence.....Steroids work great but that is kinda like using a nuclear bomb to stop a lone tank from attacking your town -- works just fine but may have unwanted side effects....
