Hypermetropia (also known as farsightedness or hyperopia) is a common vision condition where distant objects are seen more clearly than close ones. This occurs because the light entering the eye is focused behind the retina, rather than directly on it. As a result, nearby objects may appear blurry, while distant objects remain clear.
- What is Hypermetropia?
Hypermetropia, or farsightedness, is a condition where close objects appear blurry, while distant objects are clearer due to improper focusing of light in the eye. - Symptoms of Hypermetropia
Common symptoms include difficulty focusing on nearby objects, eye strain, headaches, and fatigue, especially after reading or doing close-up work. - Causes of Hypermetropia
It often occurs due to a shorter-than-normal eyeball or a cornea with too little curvature, causing light to focus behind the retina. Hypermetropia can be hereditary. - Diagnosis of Hypermetropia
An eye doctor (optometrist or ophthalmologist) can diagnose hypermetropia through a routine eye exam, using tests to measure how light focuses on the retina. - Treatment for Hypermetropia
Farsightedness can be corrected with prescription eyeglasses or contact lenses. Refractive surgery, such as LASIK or PRK, is another option for more severe cases. - Types of Hypermetropia
- Simple Hypermetropia: Caused by normal anatomical variation.
- Pathological Hypermetropia: Due to diseases or abnormal eye development.
- Functional Hypermetropia: Results from weakness in the eye’s focusing muscles.
- Hypermetropia vs. Myopia
While hypermetropia affects near vision, myopia (nearsightedness) causes difficulty seeing distant objects clearly. These conditions often require different types of correction. - Living with Hypermetropia
Most individuals with hypermetropia can manage the condition effectively with the right eyewear or corrective surgery, allowing them to enjoy clear vision at all distances.
