VISION: Part I
For Midterm 1
When the ciliary muscles flex
the lens becomes more convex
The Zonules of Zinn
pull your lens thin,
but when muscles contract,
your lens bounces back.
Your lens, too,
will grow stiff one day,
and then your near point
will move away.
More and bigger Rods,
better the odds.
Once you get to the
Ganglions,
firing is all or none.
A PHOTO needs lots of LIGHT
(PHOTOpic = Daytime, cone-dominated vision
vs. Scotopic = Night vision, rod-dominated.)
