Know Eye Refraction Disorders and How to Prevent Them

Eye refraction is the process of entering light from the front of the eye (cornea, pupil, retina) to refract it right on the retina (back of the eye). That way, objects can be seen clearly. The most common vision problem is an eye refractive error. People who have problems with eye refraction will complain of blurry vision when looking at objects that are far, near, or both.

Types of Refractive Eyes

1. Far Far (Miopi)

People with nearsightedness or myopia can see objects that are far away clearly, but have difficulty seeing objects that are far away. This condition occurs when light entering the eye falls in front of the retina. Severe myopia can increase the risk of retinal detachment, cataracts, and glaucoma.

2. Farsightedness (hypermetropy)

Farsightedness is the opposite of myopia. People with farsightedness or hypermetropy can see objects that are far away clearly, but have difficulty seeing objects that are close. This condition makes the sufferer find it difficult to read writing that is close to the eye. Farsightedness occurs when light entering the eye falls behind the retina. Farsightedness can also cause eye muscle strain, so that sufferers easily get dizzy and have headaches.

3. Cylindrical eye (Astigmatism)

Cylindrical eye conditions can occur together with farsightedness and farsightedness. Cylindrical eye or astigmatism is a vision disorder that occurs due to defects in the cornea or lens arch. This condition causes vision to be blurred or shaded, both when looking at objects that are near or far away.

4. Old eyes (Presbyopia)

Old eye or presbyopia is a condition that occurs when the lens of the eye becomes stiff, making it difficult to refract and focus light on the retina of the eye. This stiffness of the eye lens occurs due to the aging process. This condition is normal for the elderly or adults over 45 years of age.
