Myopia, or nearsightedness, is a very common vision condition in which near objects are usually viewed clearly, but distant objects often appear blurred and do not come into proper focus.

With normal vision, or emmetropia, objects are brought into sharp focus directly on the back surface of the eye, which is the retina. When this occurs, objects are seen clearly.

With nearsightedness, or myopia, objects are brought into focus in front of the retina. This is due to an eyeball which is too long for its optical components or overpowered. When this occurs, objects appear blurred.

Myopia, or nearsightedness, can be effectively diagnosed in a comprehensive vision examination and successfully corrected with minus lenses (spectacle or contact). Some common signs and symptoms of myopia include:
- Blurred vision.
- Squinting when viewing distant objects.
- Difficulty maintaining a clear focus on distant objects.
- Eye strain, tension, or discomfort.
- Fatigue after viewing distant objects.
- Headaches after viewing distant objects.
- Difficulty concentrating on distant objects.
