Hi Rick:
Good to see some action on TIPs.
I have been thinking about related issues for some time. If you look at the
back of the eye then there are lots of locations where visual stimulation will
not affect the retina. Obviously there is the blind spot. Notice that people
don’t experience
Thanks. The constant eye movement and the fovea being so small does sound
like a good physio-type answer. I had considered the idea that we do have
one and I just have not tested it in dark conditions to really see it.

Just a quick response--in some respects, we do have that blind spot, which
is why you can't look directly at a dim star at night if you want to see
it. Furthermore, our eyes are never still, so even if we are looking at
something, there is enough jitter for the foveal area to be filled in. The

TIPS had been quiet lately. A question occurred to me when talking about
rod vs cone functioning.
When light levels get low, the cones lose function. Since the fovea is
100% cones, why don't we have a blind spot in the center of our vision in
low light, low enough to lose color, but still enough
Cross-posted just in case.
