Hyperopia is a refractive condition in which the distant objects are seen clearly while close-range vision becomes difficult. The clarity of the distance vision is maintained at the cost of eyestrain depending on the degree of error. One of the most common causes of squint in children is hyperopia.
WHY DOES LONG SIGHT OCCUR?
If the length of the eyeball is too short, the rays do not get focussed on the retina. So, a clear image of the objects viewed can be obtained only at the cost of eyestrain. This explains the need for wearing glasses even though the vision is clear.
HOW DOES LONG SIGHT AFFECT VISION?
The hyperopic patient subconsciously exerts effort to maintain clear distant vision and even greater effort to see clearly at close range. This extra strain can cause fatigue, tension, headache & discomfort
WHAT ARE THE SIGNS & SYMPTOMS OF HYPEROPIA?
Difficulty in concentrating & maintaining a clear focus on close objects, eyestrain, fatigue and headache on doing close work even for a short period, burning sensation etc...
HOW IS LONG SIGHT TREATED?
If there are no symptoms and the error is mild, no glasses are required. But in the presence of symptoms, even small degree of errors should be treated.
