Re: Kaleidoscope in vision
If you have lost sight in your left eye (as you explained), and you still have the impression that you have this kaleidoscope in that eye (as well as the right eye), I would try to see a neurologist.
I get ocular migraines - when I get them, I see images in both eyes, even when my eyes are closed in a completely dark room. This is because the images are faux images in a way - Due to a process in the brain that controls vision (many different causes) - Ocular migraines are harmless. What you have may be as well, though you should be checked out by someone who has some experience in this area. I am just an ordinary person, so i know nothing about the eye, outside of what is on the internet
If you are currently seeing an optometrist, maybe go to an ophthalmologist. The opthalmoloigst will maybe refer you to a neurologist (if appropriate) if they can't find anything wrong with your eyes.
p.s. - I see strange things in my eyes all the time - if you are not experiencing them yourself, it's hard to describe them and expect someone to completely understand. Your doctor may simply not understand because he/she hasn't had anything like it. I have trouble describing my own eye problems to others.
Good luck. Let us know how things turn out.
