What is an autorefractor?


This is a machine which measures the ability of your eyes to focus and gives an approximation of your prescription.

You'll be asked to stare into the machine through two lenses and focus on a picture.

The machine will make the picture appear to be brought closer and further away; as it does this, it calculates an estimation of your prescription with how well your eyes focus on the image.
