The World’s Most Amazing Camera: Part 4 – Adaptation
The human eye is a marvel of design. All the parts work together to provide us with a vivid and colorful mental picture of our surroundings. As an astronomer, one aspect of human vision that I find particularly amazing and useful is the ability of the eye to adapt to extremely different lighting conditions. At night, the eye adjusts to be able to see stars that are 12 trillion times fainter than the sun. The way this mechanism works is ingenious and is merely one example of the cleverness of the Lord and of His grace toward us.
