What is hyperopia?
Hyperopia is a vision disorder in which near objects appear blurred while distant objects are generally seen more clearly. This occurs when light entering the eye is focused behind the retina rather than directly onto it. An eye exam can diagnose and help manage hyperopia effectively.
Diagnosing hyperopia
An optometrist usually diagnoses hyperopia during a comprehensive eye examination. This examination includes:
- Refraction test: Various instruments, including a refractometer, measure how light enters the eye and determine the required prescription for glasses or contact lenses.
- Visual acuity test: Use of a letter chart (Snellen chart) to assess clarity of vision at different distances.
- Ophthalmoscopy: Inspection of the inside of the eye with an ophthalmoscope to check the health of the retina and other eye structures.
- Convergence and eye coordination test: Assessment of how well the eyes work together is particularly important in children.
Early detection
Early detection of hyperopia is crucial, especially in children, as it can affect their learning and development. Parents should be alert to signs of visual fatigue or difficulty concentrating on nearby objects.
Symptoms of hyperopia
The symptoms of hyperopia can vary depending on the severity of the condition. Here are the most common:
- Blurred near vision: Difficulty reading or performing tasks requiring close vision, such as sewing.
- Eye fatigue: Feeling tiredness or tension in the eyes after reading or working at the computer.
- Headaches: Frequent headaches, especially after activities involving near vision.
- Strabismus: in children, hyperopia can sometimes lead to strabismus (deviation of the eyes).
- Difficulty concentrating: Children may struggle to focus in class or when reading.
Treatment for hyperopia
- Glasses are the most common solution and can effectively correct hyperopia by using convex lenses to adjust how light enters the eye.
- Contact lenses offer an alternative to glasses and may be more practical for some people.
- LASIK corneal laser surgery reshapes the cornea to improve the focus of light on the retina.
- In some cases, phacorefractive surgery with intraocular lens implantation can be implanted in the eye to correct hyperopia.
Follow-up and prevention
It's important to follow your optometrist's recommendations and have regular eye exams to monitor any changes in your vision. Good visual habits, such as frequent breaks when reading or working at the computer, can also help reduce eye fatigue.
Hyperopia is a common condition. Early diagnosis and appropriate treatment can significantly improve the quality of life of those affected. If you or a loved one are experiencing symptoms of hyperopia, don't hesitate to consult your trusted optometrist for a complete eye examination.
