I have a red ring around my pupil that only shows up when my pupils get small. This isnt pink eye, allergies, or bloodshot eyes because it dosen't look like it or feel like it. Now i have a hazel or greenish colored iris. And when my pupils get small i see a red ring that shows up around my pupil that is like a scattered ring it spikes up to different lengths in different parts on the outside of the ring. Also, if this helps when i look in the mirror when my pupils are large my eyes look very shiny almost like my eyes are glass.
