(No school on Monday; Memorial Day)
When you start at the cornea, there is a short pathway leading to your brain. The cornea is in the same area as the lens. The lens is a clear cover that covers the pupil. When people get cataracts, the lens gets very cloudy. This can be fixed by a simple procedure where the surgeon removes the faulty lens and replaces it with a plastic one
We dissected a sheep's eye not too long ago. The pupil is just a hole leading to inside the eye. When the light goes in, it travels through the aqueous humor: a jelly-like filling inside the eye. When it reaches the back of the eye, it hits the retina. The crazy thing is that everything we see is upside-down. Our eyes are so complex that they actually got me thinking about how it would be if we didn't have that advantage. Would everything be on the ceiling, like, defying gravity?? I'm an insomniac, so I have lots of time on my hands.
The image/light will eventually reach the optic nerve: the nerve that connects our eyes with our brains.
