How To Know The Eyes Of The Cylinder

The Eyes Of The Cylinder - Many people do not understand the importance of cylindrical eye tests, especially if complaints caused by cylinder eyes are considered not severe. Even though handling efforts early can make cylinder conditions more comfortable to manage.

Astigmatism or cylinder eyes occur when the curvature of the eyepiece is not entirely forming. People with round eyes have a cornea or eyepiece that curves more sharply in one direction than another. Usually, people who experience cylinder eyes also tend to experience farsightedness (hypermetropia) or nearsightedness (myopia).

Look at the Different Types of Cylinder Eye Tests

Cylinder eyes may occur at birth or appear after suffering from certain diseases, surgeries, or eye injuries. Under certain conditions, astigmatism also occurs due to a rare condition called keratoconus, which is a state in which the cornea is thinned and shaped like a cone. However, indeed, this condition does not occur due to sitting too close when watching TV or reading in dim lighting.

To ascertain the condition of your eyes, the ophthalmologist will perform a cylindrical eye test in the following ways:

  • Visual acuity test

    Your doctor may be able to ask you to read the letters on the board that are some distance in front of you, about six meters away. This test is done to find out how sharp your vision is.
  • Refraction test

    Doctors put several different lenses in front of their eyes using a device called phoropter. This lens is useful for measuring how the eye focuses on light. Doctors usually can also use a retinoscope that directs a beam of light to the eye, to see how the eye reacts to focus on fire.
  • Test for measuring corneal curvature

    The Eyes Of The Cylinder - This test is one of the cylindrical eye tests that uses a device called a keratometer. This tool serves to regulate the reflection of light on the surface of the cornea and then determine whether the eye has astigmatism or round eyes.

After performing a cylindrical eye test, the doctor will provide further treatment, namely by prescribing eyeglasses or special lenses for cylindrical eye sufferers. Also, the doctor may also recommend surgery, according to the condition of the round eye suffered by the patient.

Cylindrical tests need to do especially if you experience specific symptoms, such as headaches, tired eyes, and faint or blurred vision that occurs in various directions, both diagonally, vertically and horizontally. If that happens, you should immediately consult an ophthalmologist to get the right treatment.
