Longsight (Hyperopia)

Long Sight (Hypermetropia):

Hypermetropia or long sightedness or hyperopia is a refractive state of the eye wherein light rays are focused behind the retina. Since it is focused behind, retina receives a blurred image.

If the amount of hyperopia is small, the crystalline lens inside the eye will adjust itself to focus the light on retina. But, it leads to eye strain and head ache on near work for a long time.

If the amount of hyperopia is large, the lens cannot accommodate for whole amount of error. Thus it affects near vision mainly and then distant vision.

 

Symptoms:

Ø Eyestrain

Ø Head ache

Ø Watering on reading

Ø Defective vision for near and distance

 

Treatment:

Ø Correction of error using plus lenses for constant use.
