I'm 60. Male. Excellent health. No meds. I wear progressive lenses (Verilux Comfort).
For the past five or six years when I spent three or four minutes looking at a small digital device like my iPhone or my digital camera, when done I would have a small, circular area in the middle of my vision be pixelated for four or five minutes. Vision would return to normal. It looked like when they blur out someone's face on TV when they want to preserve identity. It is sort of like what they call 'visual snow" but only in the center of my vision and more blurry.
It does not happen when looking at a computer screen or reading a book or magazine. Only happens when vision is concentrated on a tiny screen.
No doctor was ever able to diagnose this (I think most thought I as making it up.) I've had a couple of different glasses made over the years but have had the same ones for past 3 years.
Last week I went to a new OD and got new glasses with a slightly stronger prescription (very slight.) The problem is gone. I can't believe it.
Does anyone know what might have caused this condition?
