How does hypermetropia affect vision?

It makes close objects appear clearer than distant objects

It affects the color perception of the eye

It causes blurry vision when viewing distant objects

Study Notes

Hypermetropia (Farsightedness)

A common refractive error of the eye where distant objects are seen more clearly than nearby objects
Light entering the eye is focused behind the retina instead of directly on it, causing blurred vision when looking at close objects
Caused by either an eyeball that is too short or a cornea with too little curvature

Correction of Hypermetropia

Can be corrected using a converging lens (convex lens) to help focus light rays properly onto the retina
Allows individuals with hypermetropia to see nearby objects more clearly
Power of the lens needed to correct hypermetropia depends on the severity of the condition
