called what And here a potential answers are going to
- 00:23
run right Well in order to narrow it down let's
- 00:26
take a look at what each part of the eye
- 00:28
does let's start with e the retinal ganglion cells it
- 00:32
looks like a made up phrase from a sci fi
- 00:34
film the return of the retinal ganglion but well it's
- 00:38
not that exciting These cells are responsible for transferring information
- 00:41
from the eye to the brain However since we're talking
- 00:45
about cells that see in some sense of the word
- 00:48
at least this answer doesn't fit it's not really doing
- 00:51
the seeing so much as receiving information from one source
- 00:54
and passing it along to another so in cross out
- 00:56
eat these retinal ganglion cells form the bulk of the
- 00:59
optic nerves along with the glial cells that regulate protect
- 01:03
and support the nerves as they do their information Sending
- 01:07
thing though is out as well It's like i let's
- 01:11
move on to see the bow via well the phobia
- 01:14
is a small pit near the center of the retina
- 01:16
That's responsible for sharp central vision providing us with direct
- 01:19
line of sight used in tasks like reading and driving
- 01:22
Think of it is you're focused vision or in other
- 01:24
words the number one thing you should be thankful for
- 01:27
your ability to reach the top of the scoreboards in
- 01:29
college duty But does it only see in black and
- 01:32
white know why Because this central pitting your eyes made
- 01:36
up of cones cones process color as well as visual
- 01:40
acuity so it looks like both cnn air out which
- 01:43
leaves us with b rods cones and rods are the
- 01:47
two types of cells that cover the eye and initially
- 01:49
received or see the light waves coming in The rods
- 01:53
handle the black and white which helps us see in
- 01:55
the dark so it looks like he's our answer But
- 01:58
don't worry rods Some of the best things only come
- 02:00
in black and white I'm gonna find these guys and
- 02:03
