I only notice it sometimes when I look at a blank wall. I had my eyes looked at many times about a year ago and before I had LASIK. Ugh. Now I notice a different issue, sometimes I notice a clear white shimmer floater and it goes away. Like today I was sitting on the toilet and i was looking left and I notice something kind of clear or white or like a light floating up in the corner of my right eye when I'm looking left.
