Hyperopia, also known as farsightedness, is a common refractive error where distant objects are seen more clearly than near ones. It occurs when the eyeball is too short or the cornea has too little curvature.
congrats on reading the definition of Hyperopia. now let's actually learn it.
Hyperopia can be corrected with convex lenses, such as in eyeglasses or contact lenses.
Common symptoms include difficulty focusing on close objects, eye strain, and headaches.
It is often diagnosed through a comprehensive eye examination that includes refraction assessment.
Pharmacologic agents like cycloplegic drops may be used during an eye exam to temporarily paralyze the ciliary muscle and ensure accurate measurement of refractive error.
Untreated hyperopia in children can lead to amblyopia, commonly known as lazy eye.
