Professor Lars Schmitz joins WIRED to guide us through a giant tree of life mapping the evolution of eyes in the animal ...

Having abnormally small pupils may indicate a health problem. The pupil, the dark center of the eye, determines how much light reaches the light-sensing retina at the back of the eye. Muscles in ...

If evolution occurs through gradations, the critics say, how could it have created the separate parts of the eye -- the lens, the retina, the pupil, and so forth -- since none of these structures ...

Simple schematic models for the eye have been used for more than a century 32. However, these types of simplified representation were developed with average data and had very limited potential for ...

During the study, changes in participants' pupils were monitored with an eye tracker ... aiming to build a more complete model of how involuntary pupil changes affect our perception of motion.
