A comprehensive eye exam is an integral part of assessing overall health and consists of 2 general components:

Refraction: This is the primary reason many people schedule an eye exam, the part where you’re asked “which is better, 1 or 2”. This portion assesses visual acuity (how well you see), and what your glasses prescription is (you get a copy at the end of your exam). Different lenses are used to determine your prescription, and this is done typically with an instrument called a phoropter (see picture below):

Tip: It is absolutely okay to say if two options look the same, or to ask to see the choices again.
