Amazing phenomenon illustrated on the Motorcycle Safety Foundation website:

Worth a look if you haven't seen it. I'm a believer.

 

I get that sometimes when I see a busty woman walking past. . .everything else in my field of vision seems to disappear. In all seriousness, I did try to focus and the yellow dots still vanished.

 

I have had this happen when on long boring road trips, After several hours I feel as if my vision is going bad, I do not see things correctly and I no longer consentrate as well. As this happens I get off and take a break, it is generally the beginning signs of dehydration and fatugue. Like I mentioned it takes several hours on the bike even with breaks on an hourly rotation.

 

That's three tiny dots about 2'2" away from my face and that's with extreme target fixation.

If you're constantly scanning your surroundings like you're supposed to, it should be a non issue. Plus, Once I moved about 5' away from the monitor, they never disappered.

 

interesting . if you stare at the center dot the other 3 disappear randomly . if you move your eyes from dot to dot , they don't . increasing the rotation speed means you have to look from dot to dot faster or they will start to vanish

i think people driving cars tend to look just at the road , but bike riders are looking at everything , so less likely to have this happen . until you get tired , then you tend to fixate even on a bike . you have to know when to take a break , grab a coffee , lunch , whatever

 

i guess you type faster than i do

 

What a bunch of crapola. I'll definitely know what to do if I ever run across a rotating grid with some yellow dots on it while I'm out riding. Sheesh!

Update: Went to the MSF website and finally found this. It's included with several other "optical illusions" that have absolutely nothing to do with riding motorcycles. They are simply brain teasers and are nothing more than entertainment.

 

I'll use that excuse if I ever crash - motion induced blindness made me do it. That semi-trailer tractor disappeared I swear.

 

LOL! That was going to be my answer too!!

 

Never heard of it or expierienced it while riding.
