Many people who tidI understand the importance of the cylinder eye test, especially if the complaints are caused by cylinder eyes considered not serious. whereas handling effortsince early could makes cylinder eye condition easier to manage.
Astigmatism or astigmatism occurs when the curvature of the eye lens is not fully formed. People with cylinder eyes have the cornea or lens of the eye that bends more sharply in one direction than the other. Usually people who have cylinder eyes also tend to be farsighted (hypermetropia) or farsighted (myopia).
Observing the Different Types of Cylindrical Eye Tests
Cylindrical eye may be present at birth or after suffering from certain diseases, surgery, or eye injuries. Under certain conditions, astigmatism also occurs due to a rare condition called keratoconus, which is a condition in which the cornea is thin and shaped like a cone. But certainly, this condition does not occur due to sitting too close while watching TV or reading in dim lighting.
To confirm the condition of your eyes, your ophthalmologist will perform a cylinder eye test in the following ways:
- Visual acuity test
Your doctor may be able to ask you to read the letters on a board some distance away from you, about six meters away. This test is done to find out how sharp your eyesight is.
- Refraction testDoctors place several different lenses in front of the eye using a device called phoropter. This lens is useful for measuring how the eye focuses light. Doctors usually can also use a retinoscope that points a beam of light at the eye, to see how the eye reacts to focus on light.
- Corneal curvature testThis test is a cylinder eye test that uses a device called a keratometer. This tool serves to measure the reflection of light on the surface of the cornea to determine whether the eye has astigmatism or cylindrical eye.
After performing the cylinder eye test, the doctor will provide further treatment, namely by making a prescription for glasses or special lenses for people with cylinder eyes. In addition, the doctor may also recommend surgery, according to the condition of the cylinder eye suffered by the patient.
Cylindrical eye test is necessary especially if you experience certain symptoms, such as headaches, eye fatigue, and blurred or blurred vision that occurs in various directions, either diagonally, vertically, or horizontally. If this happens, you should immediately consult an eye doctor to get the right treatment.
