Question

Near Sightedness is called?

Answer 1

Answer: Myopia

Explanation:

Near sightedness is medically known as myopia. This common vision condition affects millions of people worldwide and occurs when the eye cannot focus light properly on the retina.

In myopia, distant objects appear blurry while close objects can be seen clearly. This happens because the eyeball is slightly longer than normal, or the cornea (the clear front part of the eye) is too curved. As a result, light rays focus in front of the retina instead of directly on it, creating that characteristic blurred vision when looking at things far away.

The term "myopia" comes from Greek words meaning "to shut" and "eye," referring to how people with this condition often squint to see distant objects more clearly. You might notice someone with myopia sitting closer to the blackboard in class, holding books very close to their face, or having difficulty seeing road signs while driving.

Myopia typically develops during childhood and teenage years when the eyes are still growing. It can be influenced by both genetic factors (if your parents have myopia, you're more likely to develop it) and environmental factors like spending too much time doing close-up activities such as reading, using computers, or smartphones.

The good news is that myopia can be easily corrected with eyeglasses, contact lenses, or refractive surgery. Concave lenses are used to correct myopia because they help spread out the light rays before they enter the eye, allowing them to focus properly on the retina and restore clear distance vision.
