Nearsightedness, also known as myopia, is a common vision condition that makes it difficult to see objects at a distance. With nearsightedness, the eye is too long from front to back, or the cornea (the clear front part of the eye) is too curved. This causes light rays to focus in front of the retina, instead of on the retina, which is the light-sensitive tissue at the back of the eye. As a result, objects at a distance appear blurry.

Nearsightedness is often first noticed in childhood or adolescence. It is usually caused by a combination of genetics and environmental factors, such as spending a lot of time indoors and doing close work.

Signs and symptoms of nearsightedness

The most common symptom of nearsightedness is blurred vision at a distance. Other symptoms may include:

  • Eyestrain
  • Headaches
  • Fatigue
  • Difficulty driving at night
  • Difficulty seeing the chalkboard or whiteboard in school

Treatment for nearsightedness

Nearsightedness can be treated with glasses, contact lenses, or surgery.

  • Glasses: Glasses are the most common treatment for nearsightedness. They work by bending light rays so they focus on the retina.
  • Contact lenses: Contact lenses are another option for treating nearsightedness. They work in the same way as glasses, but they are worn directly on the eye.
  • Surgery: There are several types of surgery that can be used to correct nearsightedness. The most common type of surgery is LASIK (laser-assisted in situ keratomileusis). LASIK uses a laser to reshape the cornea, which changes the way light rays are focused.

Preventing nearsightedness

There is no sure way to prevent nearsightedness. However, there are some things you can do to reduce your risk, such as:

  • Spending time outdoors. Studies have shown that children who spend more time outdoors are less likely to become nearsighted.
  • Limiting close work. If you must do close work, take breaks every 20 minutes to look at something at least 20 feet away.
  • Getting regular eye exams. Your doctor can check your vision and look for signs of nearsightedness.

If you have any concerns about your vision, be sure to see your doctor. They can help you determine if you have nearsightedness and recommend the best treatment for you.
