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
