| There is a popular misconception that seeing is all done in
the eye. It really isn't. All the eye does is just capture the light reflected
off objects and translate them into electrical pulses for the brain to understand.
It's sort of like a microphone that's plugged into your computer. However, vision
is still related to the eye in many ways but the real 'seeing' is done by your
brain when it processes the signals.
You know about cones and rods, but do you know how they really work, and what
is this about vitamin A being so important for the eye? Now you'll find out. |
