for the last six months i have been experiencing light headedness.  My view is like when you are watching a silent movie and the scene fades to black.  that is what i experience at least 30 times a day...and 2 eye docs told me i hd the start of mild cataracts and the latest eye doc told me my eyes are perfectly and i know that isnt true, because the two previous docs noticed i had a scratch in the left eye ball, on the left side of the pupil,,,i am going to go and get a copy of the mri and the mra and see if my regular doc notices ask her if she can double check again but does anyone have an idea about the first part i had said about fading to black vision and the ningling and numbness during the fading to black vision
