Girl with Eyeglasses Thinking About Refractive Error

Have you ever heard your eye doctor talk about your refractive error? Let’s talk about what your refractive error is, how to find your refractive error, and how to correct it.

What does refractive error mean?

It refers to a vision problem caused by the shape of your eyeball. When you have a refractive error, the shape of your eye bends light improperly into your eye.

Common examples include:

  • Myopia (nearsightedness)
  • Hyperopia (farsightedness)
  • Presbyopia (difficulty focusing on close objects)
  • Astigmatism (difficulty focusing on objects at all distances)

How common are they?

If you have a refractive error, you’re certainly not alone! In the US:

  • Nearly a quarter of adults ages 40 and older have myopia.
  • A little over 8% of adults ages 40 and older have hyperopia.
  • About one-third of people have astigmatism.

What are the symptoms?

If you have it, you may experience:

  • Blurry or hazy vision
  • Double vision
  • Glare or “halos” around lights
  • Frequent eye strain and headaches

How can you find your refractive error?

People were only able to learn about it by screening for visual acuity with a chart or going to the eye doctor. Now, you can test for it at home. With the EyeQue VisionCheck or the Personal Vision Tracker, you can test your vision at home, work, or any other location you can take your smartphone.

How can you correct it?

You can correct it with eyeglasses, contact lenses, or laser eye surgery.

Did you know that you can use EyeQue VisionCheck to get the EyeGlass Numbers you need to order eyeglasses online? With your EyeQue Membership, you’ll also be able to securely track changes in your vision and refractive error over time, so you know when you need to order new glasses. This information can also help you identify sudden vision changes that may require a visit to your eye doctor.
