Eyes
The eyes are organs. They detect light, regulate the light through a diaphragm, focuses it through adjustable lenses and converts them into electo-chemical impulses in our neurons by photoreceptor cells called rods and cones. The image is converted into a set of electrical signals that are transmitted to the brain via neural pathways that connect the eye to the optic nerve and visual cortex of the brain. In short, eyes are very complex optical systems that convert light to distinguish objects and movement around us.

Can lack of sleep cause dehydration?
Yes it certainly can, this is a result of your brain using a lot more energy to maintain its energetic flow and needing to use the water reserve to cool down from overheating / overworking which causes sweating and inner dehydration. Another cause of dehydration can be a lack of water consumption in general or REM sleep (which is rapid eye movement) this is when the body falls into its semi sleeping state but still persists to lose energy while dreaming, this in turn causes sleepiness during awakening and dehydration of the mouth. So lack of sleep and the wrong sleep can cause dehydration, its always best to drink as much water as possible so your brain can keep up with its water consumptive ways.

Why are men more likely than women to be colorblind?
Yes.

For a woman to get it, she would need to have the colorblind gene on both x chromosomes. Therefore the girl´s dad would have to be colorblind and the mother at least a carrier.
