Three Common Vision Problems

Three Common Vision Problems

Most people who have trouble with their vision suffer from at least one of these three common vision problems: myopia, hyperopia, or astigmatism. These vision problems are not eye diseases, but rather a problem with the shape of your eye that causes a decrease in vision. Each one is a little different, so let’s take a look!

Myopia: What’s Right in Front of You

With myopia, distant objects are blurred. Many people refer to this vision problem as nearsightedness. With Myopia, seeing up close and reading text is typically not difficult for you, while seeing far away things or reading from a distance can seem impossible.

This common vision problem is caused by an eyeball that is too long or a cornea that is too curved. The shape of the eye determines how your eye receives light and therefore can see. The shape of your eye in the case of myopia causes light to focus in front of the retina instead of on it, making far away objects appear blurry. Myopia always receives a negative prescription.

Hyperopia: Gazing into The Distance

More commonly referred to as nearsightedness, hyperopia is when you can’t see up close. People with hyperopia commonly need reading glasses. This vision problem is caused by the opposite reason as myopia. The eyeball is too short, or the cornea is too flat.

Astigmatism: A Warped Perspective

Astigmatism is slightly different than the other two common vision problems. Instead of being uniformly curved, the cornea is more of a football shape, causing multiple focal points. With this problem, things can appear blurry at any distance, and it is often paired with one of the other two vision problems.

Generally speaking, all three of these vision problems can be corrected with spectacle and/or contact lenses.
