Clearing Up Myopia: Everything You Need to Know About This Common Vision Condition

Myopia, commonly referred to as nearsightedness, is a vision condition that affects millions of people around the world. It is a refractive error that causes distant objects to appear blurry, while nearby objects remain clear. This condition usually develops during childhood and can progress over time.

Myopia occurs when the eyeball is too long or the cornea (the clear outer covering of the eye) is too curved, causing light to focus in front of the retina instead of on the retina. This causes distant images to appear blurry, while nearby images remain clear. While it may not seem like a major problem, if left uncorrected, myopia can lead to serious eye problems later in life.

The Symptoms of Myopia

The most common sign of myopia is difficulty seeing distant objects clearly. You may find yourself squinting or closing one eye to see clearly. Other signs and symptoms may include:

  • Headaches
  • Eye strain or fatigue
  • Squinting
  • Difficulty seeing while driving or playing sports
  • Feeling the need to sit closer to the television or computer screen

The Causes of Myopia

Myopia tends to run in families, so it may be an inherited condition. However, other factors that may contribute to myopia development include:

  • Spending long periods of time focusing on close-up tasks such as reading, writing, or using electronic devices
  • Not getting enough outdoor time
  • Having an occupation that requires a lot of close-up work, such as computer programming or drafting
  • Medical conditions such as diabetes, Down syndrome, or Marfan syndrome

The Treatment of Myopia

The most common way to correct myopia is through prescription eyeglasses or contact lenses. Both options work by adjusting the way light enters the eye, allowing it to focus correctly on the retina. More recently, there has been a growing interest in orthokeratology (ortho-k) lenses or corneal reshaping lenses, which can help to temporarily correct myopia without the need for glasses or contacts.


If you are experiencing symptoms of myopia, it is important to schedule an eye exam with an optometrist or ophthalmologist. By doing so, you can get a proper diagnosis and treatment plan to protect your vision and overall eye health. Regular eye exams can also help to detect any changes in your vision and prevent serious eye diseases.
