Though the photograph technically does show the cornea, it’s the iris that makes up the eye’s brown coloration. In the human eye, the cornea is the clear, dome-shaped portion located at the ...

In a fascinating exploration of the human eye's reflective properties, researchers at the University of Maryland have achieved a remarkable feat: creating a three-dimensional (3D) reconstruction ...

Researchers at the University of Maryland have turned eye reflections into (somewhat discernible) 3D scenes. The work builds on Neural Radiance Fields (NeRF), an AI technology that can reconstruct ...

The human eye is not flat, ... With cornea pose optimization and iris texture decomposition, the researchers created a model that can compensate for blurry, low-resolution reflections.

A widely popular idea in psychology and evolutionary science suggests that the distinctive look of the human eye—particularly the white area surrounding the iris—evolved to help us communicate ...

These pictures are a sight for sore eyes. For while they may resemble the dramatic surface of the Red Planet they are actually the close-ups of the human iris.

The iris has an adjustable circular opening called the pupil, which can expand or contract to control the amount of light entering the eye, Fromer said. Ciliary muscles surround the lens.

Everyone with blue eyes inherited a tiny genetic "switch" that dilutes brown pigment in the iris. This mutation, found in all blue-eyed people, emerged 6,000–10,000 years ago, meaning they all ...

That's the goal of new research into a a tunable, low-powered iris embedded in a smart contact lens. It's a good example of the growing role of nanotechnology in human augmentation and therapeutics.
