When you are about to go in to see your optometrist for your next eye exam, what test causes you the most anxiety? No, not the “air puff” test (though that’s no crowd pleaser either).

During this test your doctor will ask you a series of questions in rapid succession about “which lens appears clearer – 1, or 2? 3, or 4? 5, or 6?”. Don’t get it wrong, or it may affect how clearly you see the world with your new glasses for the next 1-2 years until your next exam!
