Myopia

Myopia Latest News

Recently, Myopia has become a major global public health concern and it was estimated that nearly half the world’s population are expected to be myopic by 20250.

About Myopia

• It is a common vision condition in which close objects look clear but far objects look blurry. The medical term for nearsightedness is myopia.
• How does it occur?
  • For people with normal vision, light passes through the clear cornea at the front of the eye and is focused by the lens onto the surface of the retina.
  • People who are having myopic typically have eyeballs that are too long from front to back.
  • As a result, light entering the eye is focused too far forward, in front of the retina instead of on its surface.
  • It is this change that causes distant objects to appear blurry.
  • The longer the eyeball is, the farther forward light rays will be focused and the more severely nearsighted a person will be.
• Eye experts are still unsure of the exact cause of myopia, but believe it to be a mix of hereditary and environmental factors.
• It usually begins in childhood or adolescence. 
• It tends to worsen with age until adulthood, when it may stop getting worse (stabilize). In some people, nearsightedness improves in later adulthood.
• Symptoms: Nearsightedness can lead to squinting, eyestrain, headaches, and significant visual impairment.
• Treatment
  • Glasses or contact lenses can correct myopia in children and adults.
  • For adults only (with rare exceptions for children), there are several types of refractive surgeries that can also correct myopia.
  • Negative (minus) powered lenses are used to correct nearsightedness.
