30 Day Photo Challenge: Day 12

Today's challenge was a close-up. As I stated yesterday, I am fascinated by the human eye. Outside of the many unique colors, use in expressing emotion - conveying amusement, elation, sadness and anger; and usefulness in experience the many visual wonders of our world -- did you know that your eye contains a treasure trove of information about you?

The part of the eye seen by everyone each day can become a repository for substances -- for example, people with high cholesterol can get a white line around the colored part of the eye called arcus lipoides, or sometimes people that have high copper levels in their blood will have a copper ring around this colored part called a Kaiser-Fleischer ring.

Additionally, if someone looks at the back of the eye (part not seen by the casual observer)-- sometimes changes related to higher pressure in the brain/skull can be seen, or changes in the blood vessels related to diabetes, high blood pressure, infections attacking the heart, and other conditions can be seen; often at the same time as changes to similarly sized blood vessels elsewhere in the body (ex. kidney).

Isn't the eye just fascinating?
