Think back to when you were a kid… at a campground,friends house, or even your room. You want to get your favorite teddy bear or action figure, but it was all the way across the room. You couldn't see anything but the moon through your window. You wanted that bear so bad but you knew there was a whole bunch of other toys on your floor and you didn't want to trip and fall and wake mom and dad up. Yet a few minutes of staring into the darkness… and you start to see. You slowly get up head over to your toy bin. While walking over your avoiding toys that are scattered on your floor. You make it back to your bed with teddy and go back to sleep. The whole reason you saw in the dark was do to your rod cells. Your rod cells are cells that are in your retina, a small thin tissue in your eye. Without your rod cells you wouldn't be able to see in the dark! Scary! = =

=**Rod Cells**=

__Where is it:__ The Rod Cell,Cone cell, And bipolar Cell is in the retina. The retina is a small thin tissue in the inside of your eye. Even though it is small and thin it has many cells inside of the retina.

__What does it do:__ A rod cell, is of course a cell, that gives people a way to see in the dark. Without a rod cell you would not be able to see in the dark and would have a condition called night blindness. night blindness is a condition where your rod cells are damaged or not working.

 * Differences with Rods and Cones**


 * What is Night Blindness**

Night blindness, Also known as nyctalopia, is when anything interferes with your rods, Your rods detect light do you can see. When you have night blindness you can see normal in bright light (During the Day) But when night comes your rods don't work, Making you almost blind at night.

(Normal) (Night Blindness)

Cataracts can also affect how your rods cells see. Anything covering your Lens Makes your Rods not get light which means That there is a blur in your vision. Yet, there are ways to avoid Night Blindness and Cataracts. Vitamin A! And i bet as a kid your parents also said “eat your carrots they're good for your eyes”. And guess what! i know as a kid you never wanted to hear this but… they were right. But if you don't like Carrots then you can have Spinach, Kale,Sweet Potato, Mango, and Squash.
