Myopia, or short-sightedness, makes distant objects look blurry while near vision stays clear. Here is what causes it and how it is corrected.
What is myopia?
Myopia, commonly called short-sightedness, is a refractive error in which distant objects appear blurred while nearby objects are seen clearly. It happens when the eyeball is slightly longer than normal, or the cornea is too curved, so light focuses in front of the retina instead of directly on it.
Common symptoms
- Difficulty seeing the blackboard, road signs or a TV clearly
- Squinting or screwing up the eyes to see far away
- Headaches or eye strain
- In children: sitting close to the television or holding books very near
What causes it?
Myopia often runs in families and usually begins in childhood, progressing through the teenage years as the eye grows. Prolonged near work and reduced outdoor time are also linked to its rise in children.
How is it corrected?
Myopia is corrected with concave (minus-power) spectacle lenses or contact lenses that move the focus back onto the retina. For suitable adults, LASIK or other refractive surgery can reduce dependence on glasses. Children benefit from regular eye checks so their prescription stays up to date.
If you or your child are struggling to see distant objects clearly, book an eye examination at Dr. Shamsher Singh Eye Hospital, Khanna.
