eye
Let an agent explain the eye and its kinds across animals, relay anatomy, physiology, evolution and comparative examples from biological references, describe human eye health in general terms with routing to eye care professionals, and distinguish the eye from vision as a process, from eyespots and from figurative uses.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain the eye and its kinds across animals, relay anatomy, physiology, evolution and comparative examples from biological references, describe human eye health in general terms with routing to eye care professionals, and distinguish the eye from vision as a process, from eyespots and from figurative uses.
The sensory organ of vision in animals, from the camera-type eyes of vertebrates including humans, fish, amphibians and cattle, through the compound eyes of arthropods and the simple eyes or ocelli of many invertebrates, to the parietal eye of some reptiles and other vertebrates that senses light for circadian regulation; eyes detect light and convert it to neural signals, and their diversity is a classic case study in evolution.
What it is for: Detecting light and forming images.
It can be explain anatomy and kinds; relay physiology and evolution; describe eye health with routing; distinguish related concepts.
Distinguishing features
Light detection
Image formation
Many designs
Evolutionary case study
What it looks like
A spherical organ with cornea, iris and pupil in vertebrates; faceted compound eyes in insects.
Physical character
human eye diameter: about 24 mm
human retina photoreceptors: about 120 million rods and 6 million cones count
independent origins of eyes: dozens count - estimates
eye types: about 10 major designs count
How it is recognised
Light-sensing organ
Camera eyes of vertebrates, fish and amphibian eyes, cow eye, compound eyes, simple eyes of invertebrates, parietal eye
Vision is the process; eyespots are simple light detectors; the eye of a storm is figurative

What the second pass must settle
- Should human eye, compound eye and parietal eye be separate primary entries?
- How should biological references be linked?
- The registry entry has merged aliases naming animal groups and a dissection specimen; should they be split off?
