Read the passage in the human eye and answer the questions.
Eye is a natural optical device by which humans could see objects around him. It forms an inverted, real image on a light sensitive surface. It works on the phenomenon of refraction of light through a natural convex lens. However, Meena was unable to see clearly the words written on the black board placed at a distance of approximately 3 m from her. Her mother discussed the same with the doctor. Doctor explained to her about this defect of vision and its correction.

Defect of Vision: Myopia
Explanation:
- Meena is suffering from the defect of vision known as myopia.
- Myopia, also known as nearsightedness, is a condition in which a person is unable to see distant objects clearly but can see nearby objects clearly.
- In Meena's case, she was unable to see the words written on the blackboard placed at a distance of approximately 3 meters from her.
- This indicates that her eyes have difficulty in focusing the light coming from distant objects onto the retina, resulting in a blurred image.
- Myopia occurs when the eyeball is too long or the cornea (the transparent front part of the eye) is too curved, causing the light to be focused in front of the retina instead of directly on it.
- As a result, the image formed on the retina is out of focus, leading to blurred vision for distant objects.
- This defect of vision can be corrected by using concave lenses.
- Concave lenses are shaped in a way that they cause the light to diverge before entering the eye, allowing the image to be focused correctly on the retina.
- By using concave lenses, Meena will be able to see distant objects clearly as the lenses will help in adjusting the path of light entering her eyes, ensuring that it is focused properly on the retina.
- Therefore, option 'A' - Myopia is the correct answer for the type of defect Meena is suffering from.
