## What is EOM Sim?

WesternU’s CETL team presents EOM Sim, a realistic 3D eye simulator that shows the movement of the extraocular muscles of the eye. The movement of the human eye is one of the most complex actions in the body, with multiple muscles working in conjunction to make the eye rotate. With EOM Sim, you can observe and control each of these muscles individually and learn how each of them affects eye movement. Useful as both a teaching tool and a study tool, EOM Sim is designed to help medical students (or anyone who is curious about how their eyes work) learn about eye movement using a 3D simulation rather than text.

Now in Version 2: Pupillary response and fully 3D eye muscle rendering!

How To Use:
Simply touch the screen and the eyes will follow your finger. Use the sliders on the side of the screen to weaken individual muscles and simulate different conditions. By swiping left or right, you can find toggles to disable different cranial nerves. To access the pupil mode, use the flashlight button on the bottom. 
To view the 3D eye model, use the leftmost button on the bottom bar. You can rotate and zoom in this mode, and you can control where the eyes look using the joystick controller to the right. You can also interact with individual muscles to further see how each works.

EOM Sim is still in active development, and we are always looking for feedback and suggestions!
