Myopia is also known as:

The correct answer is Near-sightedness.

Key Points

• Myopia, commonly known as near-sightedness, is a refractive error where individuals can see nearby objects clearly but struggle to see distant objects.
• It occurs when the light entering the eye focuses in front of the retina instead of directly on it.
• Common symptoms include blurry vision of distant objects, eye strain, and headaches.
• Myopia is often caused by elongation of the eyeball or an overly curved cornea or lens.
• The condition can be corrected using concave lenses in glasses or contact lenses, or through refractive surgery like LASIK.

Additional Information

• Myopia vs. Hypermetropia:
  • Myopia: Difficulty seeing distant objects, corrected with concave lenses.
  • Hypermetropia (Far-sightedness): Difficulty seeing nearby objects, corrected with convex lenses.
• Presbyopia: A common age-related condition where the eye's lens loses flexibility, making it difficult to focus on close objects. It typically starts around age 40.
• Astigmatism: A refractive error caused by an irregularly shaped cornea or lens, leading to blurred or distorted vision at all distances.
• Preventive Measures: While myopia cannot always be prevented, practices such as reducing screen time, taking regular breaks while reading, and spending time outdoors can help reduce its progression.
• Global Prevalence: Myopia is becoming increasingly common worldwide, with studies suggesting that nearly 50% of the global population may be myopic by 2050 due to lifestyle changes and increased near-work activities.
