The Patient's Guide to Refractive Error Part 2: Hyperopia9:29 PM
Hyperopia, or "far sightedness" can be a more difficult concept to grasp than myopia. Myopes need their glasses to see clearly, but it is not that straightforward for hyperopes. When you think about someone that wears glasses, the classic image is a "Mr. Magoo" type that is bumbling around blind without their glasses. The thing is, hyperopes (in most cases) can see pretty well most of the time. People with only mild amounts of hyperopia generally never even know they have refractive error until their focusing system begins to decline in a condition called presbyopia (more on that later) that occurs around age 40.

Why does light fall behind the retina? Well, a patient with hyperopia has either:
- flatter cornea that doesn't bend light as much as an average cornea
- or a shorter eyeball
