Overview
Farsightedness, medically known as hyperopia, is a common vision condition where distant objects appear clearer than nearby objects. This occurs due to an abnormality in how light is focused within the eye, specifically related to the shape of the eyeball or the focusing power of the eye's lens.
Types of Farsightedness
- Simple Hyperopia: Objects at a distance are clearer than those nearby.
- Compound Hyperopia: Both near and distant vision are affected.
- Functional Hyperopia: Temporary hyperopia due to accommodation.
Causes of Farsightedness
- Abnormal Eye Shape: Eyeball being too short or the cornea being too flat.
- Genetics: Farsightedness tends to run in families.
- Age: Aging can lead to changes in the eye's ability to focus.
Risk Factors of Farsightedness
- Family History: Having parents with hyperopia increases risk.
- Certain Health Conditions: Conditions like diabetes can contribute.
- Environmental Factors: Prolonged near work without breaks.
Symptoms of Farsightedness
1. Blurry Vision: Difficulty seeing objects up close.
2. Eyestrain: Discomfort or headache after close-up work.
3. Difficulty Reading: Words might appear unclear or difficult to focus on.
4. Squinting: Attempting to see more clearly by narrowing eyelids.
Preventions of Farsightedness
To minimize the risk of hyperopia:
- Regular Eye Exams: Detect changes early.
- Eye-Friendly Habits: Take breaks during close-up work.
- Healthy Lifestyle: Maintain overall health.
Diagnosis of Farsightedness
- Visual Acuity Test: Measures clarity of vision.
- Refraction Test: Determines the exact prescription.
- Eye Health Examination: Checks for other eye conditions.
Treatment for Farsightedness
- Eyeglasses: Corrects hyperopia by focusing light properly.
- Contact Lenses: Provides a more natural field of vision.
- Refractive Surgery: Reshapes the cornea to improve focus.
When to seek medical attention ?
- Blurry Vision Persisting: Especially after age 40.
- Eye Strain: Regular headaches or discomfort.
- Family History: Parents or siblings with vision issues.
