Medical Video: 10 Great Exercises to Improve Your Eyesight
Is your vision suddenly blurry and out of focus? You could have cylindrical eyes. Yes, many people are not aware that they have cylindrical eyes if they are not checked by an ophthalmologist. If you are one of the people who experience it, you certainly want to know the cause of cylinder eyes, right? Come on, see the explanation below.
What causes cylinder eyes?
In the medical world, cylindrical eyes are called astigmatism. Cylindrical eyes are a problem in the eye that makes the sufferer unable to see clearly and focus.
Normally, the eye is shaped like a perfectly round ball. However, for those of you who have cylindrical eyes, the shape of your eyes is not really round like other normal people.
People with cylindrical eyes have the shape of a cornea or eyepiece that is not perfectly curved. As a result, the rays of incoming light cannot be spread evenly across all parts of the eye.
Under normal conditions, light rays will be forwarded to one point of the retina to produce a focused image. However, this does not apply to people with cylindrical eyes.
Because the shape of your cornea is not curved perfectly, the incoming beam of light cannot be captured at one point of the retina, but precisely at two points. This condition causes your vision to be blurry and out of focus.
According to the American Academy of Ophthalmology, a cylindrical eye can be caused by congestion since you were born. But sometimes, this can also be caused by other factors, including:
- Eye disease or eye injury. Certain eye diseases can trigger this condition.
- After eye surgery. Eye surgery can lead to scarring of the cornea, causing astigmatism.
- Keratoconus, a degenerative disorder that causes the cornea to thin out and tend to be cone-shaped.
Is it true that watching TV is too close to make eyes become cylinders?
Many people say that one of the causes of cylinder eyes is the habit of watching TV too close. He said, playing cellphones and reading in low light also caused the same thing.
In fact, all the assumptions that cause the cylinder eye are only myth mere. Relax, the habit will not cause you to have cylindrical eyes, how come.
