Let’s take nearsightedness as an example. You have trouble seeing far away because your eye focuses light in front of your retina instead of directly onto it, which would enable you to see clearly.

That means that, unlike eyeglasses, contact lenses don’t leave you with any uncorrected vision at your periphery.
