Myopia (Nearsightedness)

Like hyperopia, myopia (nearsightedness) is a common refractive error. People who suffer from myopia have greater difficulty focusing on distant objects than those who don’t. In high myopia, even near vision is affected as objects must be extremely close to the eyes to see clearly.

What is a “Refractive Error”?

A refractive error occurs when the shape of your eye prevents light from focusing on the retina (light sensitive tissue in the back of the eye) resulting in blurred vision. The most common types of refractive errors are hyperopia, presbyopia, astigmatism, and myopia.


In a myopic eye, the eyeball is either too long or the cornea (the front surface of your eye)  is too curved. Both circumstances result in light focusing in front of the retina.

Myopia may run in families and usually appears in childhood. With natural growth, it is possible for a refractive error to correct itself. However, it is also possible for the error to worsen with age.

Signs and Symptoms of Myopia

People with myopia generally have good near vision, but blurry distant vision. Common signs and symptoms of myopia include:

  • Blurred distant vision
  • Headaches and eyestrain
  • Eye fatigue and squinting when viewing distant objects
  • Difficulty reading  chalkboards or smartboards (commonly noticed in children at school)

Experiencing these symptoms does not necessarily mean you have myopia. These symptoms can be a result of many different things. However, it is recommended you visit our Optometrists to schedule an eye examination

Diagnosis Through Eye Examination

Our Optometrists will be able to diagnose you with myopia, or any other refractive error, during an eye examination. During the exam, a retinoscope or autorefractor is used to give your Optometrist an initial assessment of the refractive status of your eyes. From there, after further examination and testing, treatment options are discussed.

Treatment Options

The most common method of myopia correction is prescribed lenses. Using either glasses or contact lenses, prescribed lenses work to correct the refractive error by properly focusing light on the retina. Corrective lenses for nearsightedness will have negative powers; the opposite of a magnifying glass.

Depending on the degree of severity, prescribed lenses may be required to be worn at all times.

For those who do not wish to wear prescribed lenses, refractive surgery (laser eye surgery) is another common treatment option for myopia. Refractive surgeries alter the corneal curvature in order to correct a myopic eye. The two most common procedures are LASIK and PRK.

Consult our Optometrists in order to determine which treatment/procedure is right for you. During a consultation, your Optometrist would be more than happy to address any questions or concerns you may have regarding your myopia, and options for correction.
