Which condition is characterized by nearsightedness, with focus in front of the retina?

• A. Focus on retina
• B. Focus in front of retina
• C. Focus behind retina
• D. No refractive error

Answer: (B)

Nearsightedness happens when the eye’s optical system makes a focal point in front of the retina. Because of this anterior focus, distant objects blur while near objects stay clear. This is the defining feature of myopia: the image intended for the retina lands ahead of it, so you need to diverge incoming light with corrective lenses to move the focal point back onto the retina. In contrast, focus on the retina would be normal vision, focus behind the retina corresponds to farsightedness, and no refractive error means the eye focuses correctly on the retina.
