3D Eye Model
Turn this labeled eye around to follow light from the front of the eye to the back. The cutaway shows the layers of the eyeball wall, the lens and the structures that hold it, and where the optic nerve leaves for the brain.
An illustrative teaching model built with Scholarly. Shapes, sizes, and colors are simplified so each part is easy to see.
Free to start. Build one from your own notes, slides, or textbook PDF.
Labeled parts
Parts of the eye
The 13 parts labeled on the model, and what each one does.
- Cornea
- The clear dome at the front of the eye. It does most of the work of bending light into the eye.
- Aqueous humor
- The watery fluid between the cornea and the lens. It nourishes them and keeps the front of the eye in shape.
- Iris
- The colored ring of muscle that changes the size of the pupil to control how much light gets in.
- Pupil
- The opening in the center of the iris. It looks black because light passes through it into the eye.
- Lens
- A clear, flexible structure behind the iris that changes shape to focus light on the retina.
- Ciliary body
- A ring of muscle that changes the shape of the lens, and makes the aqueous humor.
- Suspensory ligaments
- Fine fibers that hold the lens in place and connect it to the ciliary body.
- Vitreous humor
- The clear gel that fills the large space behind the lens and keeps the eyeball round.
- Retina
- The light-sensitive layer at the back of the eye. Its rods and cones turn light into nerve signals.
- Fovea
- A small pit in the retina packed with cones. It gives the sharpest, most detailed vision.
- Choroid
- A layer full of blood vessels between the retina and the sclera that supplies the retina.
- Sclera
- The tough white outer layer that protects the eye.
- Optic disc and optic nerve
- The optic nerve carries signals from the retina to the brain. The optic disc, where it leaves the eye, has no light receptors, so it is called the blind spot.
For class and projects
Using this model for class or a project
For studying, follow the path of light on the model: cornea, aqueous humor, pupil, lens, vitreous humor, retina. Then follow the signal from the retina through the optic nerve. Most exam questions about the eye follow one of those two paths.
For an eye model project, use it as a reference for the layers of the eyeball wall: sclera on the outside, then the choroid, then the retina. Keep the lens behind the iris, not in front of it.
Teachers can show the model on a classroom screen while explaining focusing, near and far vision, or the blind spot. For a course that needs the extraocular muscles or the rods and cones up close, you can build your own version from your notes.

FAQ
Eye model questions
What are the main parts of the eye?
The cornea, aqueous humor, iris, pupil, lens, ciliary body and suspensory ligaments, vitreous humor, retina and fovea, choroid, sclera, and the optic nerve, which leaves the eye at the optic disc.
How does the eye focus light?
The cornea bends incoming light, and the lens fine-tunes it. The ciliary body changes the lens's shape: it becomes rounder for close objects and flatter for distant ones, so the image lands sharply on the retina.
Is this eye model anatomically exact?
No. It is a simplified teaching model with the parts enlarged and spaced out so each one is easy to see. It is not a medical atlas and is not for clinical use.
Can I use this model for a school project?
Yes, you can use it as a reference while you study or build a physical model. Exporting pictures or video of models you build yourself needs a paid plan.
Can I make my own 3D eye model?
Yes. Sign up, choose 3D model, and describe what you need or add your notes. Scholarly builds a labeled, interactive model in a few minutes. A full build uses 1 AI Creation Credit, and you confirm it first.
