I went to the eye doctor today to see why my vision gets blurry and changes color and depth he even checked my ocular nerve said nothing's wrong ??

See an ophthalmologi: You need to see an ophthalmologist. You may need visual field test, ishihira color vision test, color desaturation and light intensity. What do mean by color change the object or the eye? Is it one eye or both?

Blurry vision: Blurred vision and changes in color of vision can be due to: optic nerve perfusion issues (check all meds; BCP often culprit; check Blood pressure), needing new glasses, brain flow issues (ie, ocular migraine: VA changes without headache); be sure pupils & HVF visual field were done to be sure all is ok.
