That's because the there are more cone cells on your fovea. Cone cells (for colour vision) only work at optimum in well lit surroundings.Im_Dooomed wrote:

I thought they did this on purpose because in real life your peripheral vision is stronger.
On the periphery there are more rod cells (for black and white vision) which also work good in low-light surroundings.
Try looking at a coloured low-light source at night (e.g. a red LED)! You'll only see it black and white in the periphery.
So, if you focus a low light source at night, you won't see it, but you'll see it a little off center, except of course if you focus it at your blind spot.
But yes, those same rod cells also have a faster response time.
