Definition

1. Noun:
   • A vision condition, specifically a refractive error of the eye: Myopia is an eyesight abnormality where the eye's refractive power is too strong relative to the length of the eyeball, or the eyeball is too long. This causes light rays to focus in front of the retina instead of directly on it, making distant objects appear blurred while close objects can be seen clearly. It is commonly known as nearsightedness or shortsightedness.

Usage and Examples

• General Usage:
  • Myopia is often diagnosed in childhood and can progress during the teenage years.
  • Wearing glasses or contact lenses is a common way to correct myopia.
• In a Medical/Technical Context:
  • The ophthalmologist explained that her myopia was due to axial elongation of the eye.
  • High myopia increases the risk of certain eye diseases later in life.

Advanced Usage

• "Pathological myopia" or "Degenerative myopia": A severe, progressive form of myopia associated with degenerative changes in the back of the eye (posterior segment).
  • Patients with pathological myopia require regular monitoring for retinal complications.
• "School myopia": A term sometimes used to refer to myopia that develops and increases during school-age years.
  • Increased near-work activities are considered a risk factor for school myopia.
