I am a 24 year old female. For some time now I have noted a very odd sensation in my right eye after turning off lights or going from a bright space into a darkened room. The eye feels odd, oily and larger than my other eye coupled with an almost total loss of vision for that eye, not at all painful but irritating and disconcerting. The past few weeks, however, I have become aware that this is becoming an all day, every day thing. Regardless of light my eye feels filmy and my vision blurred. I will be going to an optometrist as soon as possible, still I would very much like to go into my appointment with some idea as to what is happening to my eye. So there you have it, my question is what on earth do these symptoms indicate?
