It DOES exist now! Some use IR laser, some use normal, ambient light.

Not anymore.

Those are early and crude technology dating back to the infancy of eye 
tracking.

Now, you have eye tracking imbeded into pilot's helmets used for target 
selection. About 1 arc minute acuracy and 0.1~0.2 second response time. 
Takes the eye and head position into acount. Actualy deployed for well 
over 10 years... Standard isue in F16 and F18 fighters.

You also have "civilian" versions that are somewhat slower and much less 
acurate. Some of those don't need to be worn, but are placed in front of 
you, like on top of your monitor and don't require you to stay 
stationary: it locates your head, pinpoints your eyes and find where 
they are looking. Still expensive.
Acuracy of about 1~2°, response time from 0.5 to 2 seconds.
