It seems whenever I look through my right eye, all I see is a purple blur. What do I do/what is happening to me?

Needs evaluation. I am guessing that a short time ago the right eye could see well. And that the blur has appeared over the last several weeks (i hope not longer). There are many causes but most relate to either the retina or the optic nerve since apparently your eye is not red, painful or had a history of trauma. You need to see an ophthalmologist right away to get this diagnosed.
