Understanding Short-sightedness (Myopia)

Short-sightedness, or myopia, is a common refractive error where individuals can see near objects clearly but distant objects appear blurred. This happens because the eye focuses the image of distant objects in front of the retina, rather than directly on it.

Key Characteristics

• Vision of Near Objects: Clearly perceived.
• Vision of Distant Objects: Blurred or indistinct.

Corrective Measures for Myopia

To correct myopia, a lens is needed that diverges light rays slightly before they enter the eye. This allows the eye's natural lens to focus the image precisely on the retina.

• The type of lens used is a concave lens. Concave lenses are thinner in the middle and thicker at the edges, and they spread out light rays.

Analysis of the Correct Statement

The correct statement accurately describes myopia:

• It correctly states that near objects are seen clearly.
• It correctly states that distant objects are seen blurred.
• It correctly identifies the use of a concave lens for correction.

Therefore, the statement aligning with the definition and correction of short-sightedness is confirmed.
