It’s not just artificial lights.
It can be something as simple as sunlight flickering through trees or guardrail posts on the highway.
That infernally omnipresent ‘ticker’ at the bottom of all the TV news is murder.
I have to keep messing with the screen size on my TV to try and get rid of them and *still*, shows like FoxNews has a million twirling, flickering things moving on their studio backgrounds that I can’t stand.
I can’t tolerate the sight of cars moving through the intersection while I’m at a stoplight.
[and unfortunately I have the peripheral vision of a horse, apparently..it’s almost impossible to just ‘look away’]
It’s a neurological thing they don’t know how to “fix”.
Some flourescents, however, can just about make me jump out of my skin.
I can stand being in Lowes about 10 minutes before I have to bug out of there.
The ones hubby has in the machine shop are intolerable for any amount of time.
They don’t bother him at all.
Most guys get through 8 ~ women do far better than I do.
Each frequency that you can detect in your vision has a different refresh rate ~ which is one of the reasons we can tell these blends are different colors. Not everybody has the same number of red, green or blue receptors, and not everybody has rods arrayed in the same manner ~ some people actually have rods all across the retina. Most people have them mostly outside the central portion of the retina.
You could easily have a surplus of red cones ~ and that'll give you a trip ~ I can see a redhead 10 miles across the ice and anybody else better be much closer.
So, just use Google.com to search for COLOR BLINDNESS TEST ~ see what it tells you. Those sparkles and twinkles could simply be your visual cortex telling your extra red cones and possible centrally positioned rods are talking to it!
