Hi, or should that be eye!?
Here is a model of the human eye which is a very realistic representation. The color of the Iris can be changed and the scale of the pupil can be resized to whatever you require. Lighting is included and can be rotated 360 Degrees around the model. It is possible to duplicate the model so you can use it within your human (or whatever) model. If you are creating a cyclops then you're good to go!
Please refer to the Documentation on how to open/import this model
As always, any problem please let me know
Many thanks and have a lovely day!
Purchasing this Model also supports the Blender Development Fund :)
