Understanding Refractive Errors
There are four common refractive errors: myopia, hyperopia, astigmatism, and presbyopia. For the purposes of this article, I’m going to focus on the first three and discuss presbyopia at another time.
Myopia, otherwise known as nearsightedness, makes it difficult to see objects that are far away. In other words, reading a scorecard would not be an issue, but reading a distance sign on the golf course would be a challenge.
Conversely, hyperopia (or farsightedness) causes problems with seeing close objects clearly. Someone with hyperopia could read the distant sign but not her scorecard.
Astigmatism is less about near or distance vision and more about a person’s ability to focus. Due to an irregularly curved cornea, someone with astigmatism often experiences blurry or distorted vision associated with the distance of an object.
In all cases, symptoms of refractive errors include haziness, glare around bright lights, squinting, or difficulty driving at night. They can also cause headaches, eye strain, or double vision.
Not only can this impact life in general, but an uncorrected refractive error could increase your golf handicap.
