Green Eyes In Beautiful Detail

Wrote a poem about green eyes before, here are two videos I made lately:

Did you think the eyes are smooth spheres? Macro view of this eye reveals a pattern that reminds me of craters.. Maybe on Alien territories 😛

What do the patterns of this iris remind you of? How about Mediterranean sea, or a bizarre suggestion by a friend- Petri dish or sperms surrounding an egg.

Ok, some descriptions don’t sound pretty… Nevertheless, how intricate are the designs of out eyes? Evolution has created endless forms most beautiful! Spare a moment to be grateful for our sight and these beautiful & well designed features…

The iris is a contractile structure, consisting mainly of smooth muscle, surrounding the pupil. Light enters the eye through the pupil, and the iris regulates the amount of light by controlling the size of the pupil. The iris contains two groups of smooth muscles; a circular group called the sphincter pupillae, and a radial group called the dilator pupillae. When the sphincter pupillae contract, the iris decreases or constricts the size of the pupil. The dilator pupillae, innervated by sympathetic nerves from the superior cervical ganglion, cause the pupil to dilate when they contract. These muscles are sometimes referred to as intrinsic eye muscles. The sensory pathway (rod or cone, bipolar, ganglion) is linked with its counterpart in the other eye by a partial crossover of each eye’s fibers. This causes the effect in one eye to carry over to the other.

Nature will bear the closest inspection. She invites us to lay our eye level with her smallest leaf, and take an insect view of its plain.

–Henry David Thoreau 

“The soul, fortunately, has an interpreter – often an unconscious but still a faithful interpreter – in the eye.” 

— Charlotte Brontë, Jane Eyre

About weak points [of the Origin] I agree. The eye to this day gives me a cold shudder, but when I think of the fine known gradations, my reason tells me I ought to conquer the cold shudder.
