Farsightedness, or hyperopia, is a vision condition in which the distant objects will be visualized clearly, but close ones won’t come into a proper focus. Farsightedness happens when eyeball is too short or the cornea is having too little curvature. As a result, the eye cannot properly focus the light which enters it. For the near objects, the eye needs to accommodate even more.
What are the symptoms you may have?
Most common symptoms of hyperopia involves difficulty concentrating and maintaining a clear focus on the near objects, fatigue and/or headaches after doing a close work, eye strain, aching or burning eyes, and nervousness or irritability after sustained concentration. The most common symptom was 'tiring' of the eyes . Difficulty of seeing with the two eyes can occur, as well as, difficulty with the depth perception.
How does this happen?
Hyperopia is mainly caused by:
Low converging power of the eye lens due to the weak action of ciliary muscles (a ring of muscles around your lens)
Abnormal shape of the cornea
Farsightedness usually occurs from the birth, but children have a very flexible eye lens, which helps make up for this problem.
How does your doctor diagnose hyperopia?
A simple vision test will reveal a problem with your vision. An autorefractor or retinoscopy will reveal farsightedness. In some cases especially in children, your doctor will have to dilate your pupils with eye drops to detect the exact degree of the problem and find the spectacle power. In this case a second test, a few days after the dilatation, will be needed before the spectacle power is fixed.
The treatment is by corrective spectacles or contact lenses.
