Hardware and software for eye deviation detection glasses with dual cameras

Hello everyone, I am trying to make something that will help my brother. Long story short, he has a lazy eye. He can correct it when he realizes the eyes deviates, but obviously he cannot think about it every second of the day.
What I want to do is put two small cameras in a pair of glasses, so they can detect when one eye deviates from the other. I would like the trigger of detection something like a small red light turn on (that he can see, of course) when there is deviation.

I imagine this will is a fairly simply project, with the only real obstacle being the programming of the cameras to recognize the pupil from the rest of the eye and eyelids, and establishing the pattern between the two pupils.

I need to know the hardware necessary (Type of chip for the programming, type of cameras, battery, etc.),
The software to program the recognition of eye deviation (and how to program it onto a chip),
And how to connect all of these components.

Clearly, I don't know much about electronics, but I will be researching all of this so I am not just blindly following instructions. I just need help with the basic information to point me in the right direction.

Please feel free to send me an email at Lucassteele101@ hotmail.com
Thank you all in advance!

This kind of technology already exists, and I expect it could be adapted for your purpose.
However, if you are a complete beginner in electronics and programming, it would require a steep learning curve to create a system.
But if you could interest a research and development company, the device could probably become a commercial success.

May I suggest that you google: eyeball detection camera

Thanks for the reply!
I'm more than ready to take on that curve, but you're right that it would be much better finding someone who knows exactly what they are doing.
The problem with making this a 'commercial success' is that where my brother can actually control his eye through will alone, the large majority of people with what is called amblyopia cannot controll their eye movements.
The google search has yielded some interesting results, im disappointed that I haven't already looked this up!

Thanks!
