Hyperopia (Farsightedness)

Overview

Hyperopia is a refractive error in which parallel light rays focus behind the retina due to a short axial length or insufficient refractive power. Mild cases may be compensated by accommodation, while more severe cases cause blurred near vision and eye strain; high hyperopia in children can cause amblyopia and esotropia.

Symptoms

• Blurred near vision
• Eye fatigue
• Headache
• Difficulty reading
• Poor concentration

Treatment

Caused by a short axial length or insufficient refractive power. Correct with convex lenses; children need timely refraction testing to prevent amblyopia.

Dietary advice

Eat a balanced diet with plenty of vitamin A-rich foods, and maintain eye hygiene.
