Document Summary
Waves enter your eye as light comes in towards the retina. Cones and rods detect light: cones detect different colours; rods only detect the intensity of the light. There are photoreceptors that detect the light; unlike other neurons, which cannot convert electromagnetic waves into energy. Photoreceptors make synapses onto cells to carry information to visual sensors in the cortex will go to the cortex the center. From the ganglion cells it will go to the thalamus and from the thalamus it. The visual field there is the right and the left visual field where the nose is. The difficulty for us is that each eye can see both visual fields. The left eye sees from the left visual field to part of the right visual field, and the same goes for the right eye. Therefore the central part is seen by both eye: key point is that the information crosses.
