Hypermetropia is the difficulty in seeing near objects than distant objects. It is also known as farsightedness or hyperopia. Suffering from hypermetropia makes the close objects so blurry that one can't do tasks such as reading or sewing.
Hypermetropia is caused due to visual image getting focused behind the retina rather than on it. It may be caused because of the eyeball being too small or the focusing power being too weak. Hypermetropia is often present from birth but children have a very flexible eye lens which helps in making up for the problem. The condition is developed in most children. As time passes, glasses or contact lenses may be required in correcting the vision. If the family has members who have hypermetropia, one is also more likely to get hypermetropia.
The symptoms of hypermetropia are
Aching of the eyes
Blurred vision of closed objects
Strabismus (crossed eyes) in children or squint
Straining of the eyes
Headache while reading
A general examination of the eye to diagnosis hypermetropia may include
Eye movement testing
Examination of retina
Hypermetropia is not a disease and is otherwise normal and healthy. Hypermetropia is easily corrected with the help of glasses or contact lenses. Surgical procedures are also there for correcting hypermetropia and can be used for those who do not wish to wear glasses or contact lenses. Procedures to correct hypermetropia include H-LASIK, photorefractive keratectomy for hyperopia (H-PRK), thermal keratoplasty, and conductive keratoplasty (CK). Hypermetropia can also be corrected by intraocular implants. People who have a history of glaucoma, keratonocus, inflammatory eye diseases, herpes simplex keratitis or past eye injuries or surgeries should avoid laser surgery to correct hypermetropia. Rue can be prescribed for eye-strain. A homeopathic practitioner should be consulted for a proper suggestion. Vitamin A and C, magnesium, zinc and selenium can help in strengthening the retina and improving vision. Flavonoids present in bilberry and eyebright improves visual clarity.
Hypermetropia can be a risk factor for glaucoma and lazy eyes.
Hypermetropia can't be prevented. Straining of the eyes may be prevented by resting the eyes when they are overworked, blinking often and periodically changing the eyes' focus while driving or doing close work for prolonged time period.
