Hyperopia is a common refractive error that affects how the eye focuses light. In hyperopic individuals, light rays converge behind the retina instead of directly on it, causing blurred vision of nearby objects, while distant vision may be normal or even sharp.
This refractive error is usually caused by a shorter eye length or a cornea with a flatter curvature. This results in light rays not being refracted correctly and not focusing properly on the retina.
Symptoms:
- Blurred vision of nearby objects, especially in low-light conditions.
- Eye strain, headaches, and tension in the eyes after reading or engaging in tasks that require near vision.
- Difficulty focusing on nearby objects.
- Squinting to see up close (in children).
- Excessive tearing.
- Photophobia (sensitivity to light).
In some cases, hyperopia may not present obvious symptoms, particularly in children and young adults, who can accommodate their eyes to compensate for the refractive error. However, over time, this ability to focus may decrease, leading to the onset of the aforementioned symptoms.
Treatment:
Hyperopia can be easily corrected with corrective lenses, such as glasses or contact lenses. Convex lenses help focus light rays onto the retina, providing clear vision both near and far.
In some cases, refractive surgery may be an option for permanently correcting hyperopia. Techniques such as LASIK or PRK can modify the shape of the cornea to achieve proper light focusing.
It is important to consult an ophthalmologist if you experience any symptoms of hyperopia. A comprehensive eye exam can determine if you have this refractive error and recommend the most appropriate treatment for your situation.
