Some people have experienced some problems in the eye, one of them is refraction of the eye. There are several conditions of eye refraction disorders that you need to know, some of which are myopa, hypermetropia, astigmatism, and presbyopia.

Eye refraction disorder is a common disorder in vision, a condition in which the light entering the eye cannot be focused clearly. This makes the shadow of the object look blurry or not sharp. The cause can be because the length of the eyeball is too long or even too short, changes in the shape of the cornea, and aging of the eyepiece.

Eye refraction abnormalities can be classified into several types, including:

  • Nearsighted. People with nearsightedness or miopi can usually see objects close in clear and difficult to see objects with long distances. Conditions caused, long eyeballs or too strong corneal refractive strength (too convex). Shadows of objects will fall in front of the retina, without the help of glasses. Severe myopia increases the risk of retinal ablation, cataracts and glaucoma.

  • Farsighted. The nearsightedness is the opposite condition of myopia. People with farsightedness or hypermetropy can usually see distant objects but have difficulty seeing objects that are close. This is because the eyeball is too short or the strength of the cornea is too weak (less convex). Shadows of objects will fall behind the retina. Nearsightedness can cause tension in the eyes to headaches. This condition is usually due to heredity, but can also occur without a history of farsightedness in the family. In addition, this condition can also occur in corneal dystrophy, congenital cataracts, retinitis pigmentosa and microphthalmia.

  • Cylinder eyes. Cylinder which is medically called astigmatism, is a visual impairment caused by a defect in the lens or corneal arch. This disease causes blurred vision in a range of distances. People with myopia and hypermetropia can also experience this condition. If left unchecked, astigmatism can cause eye strain, headaches and tired eyes. These cylindrical eye conditions can be overcome with glasses, contact lenses, and laser eye surgery.

  • Old eyes. This condition is referred to as presbyopia, which is a condition of loss or reduced ability of the eye to regulate the lens's curvature to adjust for changes in vision distance (refractive ability). This is related to age and is a natural change. Presbyopia generally starts in people over the age of 35 years.

Medical Handling of Eye Refraction Disorders

Eye refraction abnormalities are difficult to prevent, but can be diagnosed through an eye examination, to be treated with appropriate treatment. Examination of refractive abnormalities can be done at the ophthalmologist, or in the nearest optics.

  • Use glasses. This is a simple and safe choice to improve the condition of eye refraction disorders. Professional optical officers can provide the right lens size.

  • Use of contact lenses. Some people feel using contact lenses more comfortable, and make clearer vision and a broader field of vision. It is important to maintain hand hygiene, and clean and use the lens properly. Consult an ophthalmologist for proper use of contact lenses.

  • Underwent refractive surgery. This action is to change the shape of the cornea permanently, so that it returns the focal strength of the eye. There are many types of refractive surgery. An ophthalmologist can help decide which type of refractive surgery is appropriate for your condition.

Do not hesitate to see a doctor and professional optics, if you feel the symptoms of eye refraction abnormalities. The sooner the disorder is repaired, the better it will be for your visual sense activities.
