Many people don't understand the importance of the cylinder eye test, especially if the complaints caused by the cylinder eye are considered not severe. Whereas early handling efforts can make cylinder eye conditions easier to manage.
Astigmatism or cylindrical eyes occur when the curvature of the eyepiece is not fully formed. People with cylindrical eyes have a cornea or eyepiece that is curved more sharply in one direction than another. Usually people who experience cylindrical eyes also tend to experience farsightedness (hypermetropia) or farsightedness (myopia).
Look at the Different Types of Cylinder Eye Tests
Cylinder eyes may occur at birth or appear after suffering from certain diseases, operations, 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 thinned and conical in shape. But certainly, this condition does not occur due to sitting too close while watching TV or reading in dim lighting. To determine the condition of your eyes, the ophthalmologist will do 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 some distance away from you, about six meters. This test is done to find out how sharp your vision is.
Refraction test
Doctors place several different lenses in front of the eye using a device called a phoropter. This lens is useful for measuring how the eye focuses light. Doctors usually can also use a retinoscope that directs a beam of light to the eye, to see how the eye's reaction to focus on light.
Test for measuring corneal curvature
This test is one of the cylindrical eye tests using a device called a keratometer. This tool serves to measure the reflection of light on the surface of the cornea and then determine whether the eye has astigmatism or cylindrical eyes.
