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.

I had pink eye and so did my husband and kid all at the same time. My husband had it the worst and the gal at Sprouts said to use Colloidal Silver. We did in all our eyes but lots of times in my husbands who had full blown hot red eyes goopy, not like ours. He went to the doc three days later and started antibiotics "Polymyxin B Sulfate and Trimethoprin Ophthalmic" or something close to that as it's such fine print I can't read the exact spelling. Anyway.... within a few days, pink eye starts to go away, but not completely.
One week later, loss of vision in a cloud he described as looking through brown panty hose in one area on his left eye that blocked his nose area view. Went to the opthomalogist and he saw nothing. Got worse over the weekend. Went back to optho. He still saw nothing. Went to a retina specialist, emergency detached retina surgery the next day. At this time: He is laying beside me in pain and can't see as the surgery was last night. Too early to tell if surgery was successful or not.

Another answer.
It is believed that the New Zealand lizard-like reptile called the tuatara, has a third eye (or pronounced photoreceptive eye).
lizard ( Many lizards have a third eye called a parietal eye (or pineal eye). With this eye they cannot see 3D figures or images
The tuatara, a lizard-like reptile that lives only in New Zealand, has those three "eyes." It belongs to a group of reptiles that once included many other creatures, but today, the tuatara is the only surviving member of that group.
To understand where the tuatara's "third" eye came from, scientists studied a small growth attached to the front of the reptile's brain, a gland my called the pineal body.
In some lizards, the part of the brain that is related to this pineal body is shaped much like an eye. It has a lens-shaped outer wall, a transparent covering, and a retina with pigment.
Scientists think that this "pineal eye" does not help most lizards see, but in the tuatara, the pineal eye is fully developed, giving the creature a "third eye" through which to see!
The tuatara, a lizard like reptile that lives only in New Zealand. It is born with a third eye on the forehead but later on, as it reaches adulthood, this third eye is covered by thick skin.
