Hypermetropia, also known as far-sightedness, is a refractive defect where a person can see distant objects clearly but cannot see nearby objects distinctly.

In a myopic eye, the image of a distant object is formed in front of the retina, not directly on the retina itself. This defect can arise due to (i) excessive curvature of the eye lens or (ii) elongation of ...

A person with myopia has the far point nearer than infinity, allowing them to see clearly up to a distance of a few meters. However, distant objects appear blurry.

Myopia, also known as nearsightedness, is a refractive defect where a person can see nearby objects clearly but cannot see distant objects distinctly.

The three common refractive defects of vision mentioned are (i) myopia or near-sightedness, (ii) hypermetropia or farsightedness, and (iii) presbyopia.
