There are a few different types of eye refraction machines on the market, but the most common is the ocular tonometer. This machine uses an ultrasound beam to measure the thickness of your eyeball. It then uses this information to calculate your corrected distance from straight ahead. 

Another type of eye refraction machine is the optokinetic vergence test (OCT). This machine uses a movement sensor to measure how much you shift your eyes when looking at different objects. This data is then used to calculate your corrected distance from straight ahead.
