What is the primary symptom of presbyopia?

The primary symptom of presbyopia is difficulty focusing on close objects. This condition is commonly associated with aging, as the eye's lens loses elasticity, making it more challenging to adjust focus for near vision tasks such as reading or sewing. People with presbyopia often find themselves having to hold reading materials further away to see them clearly, which is a hallmark sign of this condition.

Other options present various visual discomforts or conditions. Blurred vision at night relates more closely to issues such as night blindness or cataracts rather than presbyopia. Increased sensitivity to light can be attributed to many factors but does not specifically define presbyopia. Redness in the eye may indicate eye strain or irritation but is not a symptom of presbyopia itself. Thus, the difficulty in focusing on nearby objects truly encapsulates the essence of presbyopia.
