The Chromatic Eyes of Balloon Fish

Balloon fish reside in the warm seawaters of South-eastern Asia. When excess amounts of light fall on them, the eyes of this fish act as "chemical sun-glasses". The eyes of this 1 inch long (2.5 centimeter) fish show properties similar to photochromic lenses, the colours of which can become more or less intense depending on the strength of the light.

The system functions as follows: When the fish encounters excessive light, the chromatic cells called "chromatophore", which are located around the transparent layer (cornea) of the eye, start to release a yellowish dye (pigment). This pigment covers the eye and acts as a filter reducing the intensity of light, which enables the fish to see more accurately. In dark waters, this pigment disappears and the eye receives the maximum possible amount of light.

It is obvious that this system is a product of conscious design. These cells releasing or clearing pigments is regulated consciously and cannot be considered as a product of coincidence. It is just another manifestation of the perfection in the creation of God that an irreducibly complex organ structure such as the eye should be equipped with such a flawless chromatic system.
