The eyes are one of the senses of the human body that serves for vision. Although its function is essential for human life, but often less unnoticed, so many diseases that attack the eye is not treated properly and cause impaired vision to blindness.
Vision problems most commonly experienced are myopic, may be a myopic view distant objects, nearsightedness see objects at close range,
myopic when it is reading that is usually experienced by those aged above 40 years of age or a mixture of myopia and myopic view distant objects when you're reading.
All types of myopic eyes was essentially a distraction to focus the image object being viewed or refractive disorders (Ametropia).
Abnormalities of refraction (Ametropia) is a distortion parallel rays reflected from objects that we see, where the rays are refracted by the lens of the eye in a relaxed state is not exactly on the retina. Abnormalities of refraction can be overcome by using glasses or contact lenses.
If you have complaints myopic in your eyes, consult your eye doctor or optical medical personnel to be given advice and solutions to solve your problem. It is recommended also for eyes examined at least once a year, so that your complaint can be treated early and prevent more severe disease for the disorder - a disorder that occurs in the eye that can interfere with the activity to cause blindness. Routine eye examinations can be performed more frequently in those with a family history that has a refraction disorders, high blood pressure, diabetes or cataracts.
Various kinds of abnormalities of Refraction
Eye Myopia
Often said to be nearsighted, namely the decrease in distant visual acuity when compared with normal people. The cause of myopia is the axis of the eyeball is too long or the refractive power of the eye lens is too strong. Complaints are usually felt by people with myopia are blurred in seeing distant objects, the eyes get tired, dizzy and often watery. This disorder can be corrected with the glass minus / concave.
Hipermetrop eye.
Namely patients with this disorder complain of blurred vision acuity both near and far. Cause Hipermetrop is the axis of the eyeball is too short or the refractive power of the eye lens is too weak. Complaints are usually felt by people hipermetrop is opaque in to see objects near and far, eye fatigue, dizziness and frequent watering. This disorder can be corrected with lenses plus / convex. This situation arises in many children, especially children who were born prematurely, with age then there is the growth of the eyeball so that the size of the correction lens decreases.
Asigmatisme eye.
Asigmatisme eye or eyes is also often called cylindris ie visual acuity abnormalities are caused because people can not see as clearly shown in one plane so that the patient usually feels shaded in seeing distant objects. This is because not the same as the curvature of the cornea and corneal surface is uneven. Asigmatisme eye can be corrected with lenses cylindris.
Handling
- There are various handling: Namely with the use of conventional eyeglasses, prescription eyeglasses should be given the maximum according to the required size is used to stimulate the nerves of vision.
- With the use of contact lenses, contact lenses with the use of more patients are required to maintain cleanliness.
- With Refractive surgery (Lasik) is by thinning or incision in the cornea to reduce the thickness, is generally performed on patients has been outstanding for more than 22 years, assuming the shape of the eyeball has a maximum and cooperative patient.
- With clear lens surgery, performed in patients with very high miop that does not allow in doing Lasik, or it could be planted in front of the lens iris.
