So before visiting an eye specialist, it is really important to learn more about the types of eye test that the ophthalmologist might ask you to perform. These eye tests are the best ways to determine the kind of problems your eyes are facing and the right kind of treatment you need to treat your eyes. So, without wasting any time further, it is time to get your names enrolled for the tests for determining the current scenario of your eyes.
Below are the various eye tests conducted for different eye diseases or problems.
The most common form of eye test that you might care to learn about is the Refraction. This method is used for determining eyeglass prescriptions. You need to look at a chart around 20 feet away or in the mirror. Through this method, you will get to tell the doctor if the images or letters are clear or blurry. This test will further help doctors to prescribe the lenses of right measurements as well.
2. Visual Acuity test:
A basic example of eye test has to be the visual acuity test. It is probably the first exam that crosses your mind when you picture yourself in the doctor’s chamber. Using just an eye at one time, you will be asked to read letters from the sign, which is positioned in a specified distance from you. The optometrist is the one to be using your responses for determining the vision level of the eye and further comparing it with the standard 20/20 vision.
3. You Have The Applanation Tonometry:
This test is widely used for measuring the pressure and is amount taken to flatten a portion of the cornea. Pressure readings are important for doctors who are diagnosing and keeping track of the glaucoma rate for sure. During the execution of the test, eye drops are given to the eyes to numb the eye for a second and then the doctor presses the eyes lightly with a special tool, also known as tonometer.
4. Corneal Topography Is Another Option:
Another type of eye test is corneal topography. This is also known to be a computerized test, which helps in mapping the curve of the cornea. It is widely used for detecting issues with the eye’s surface area like scarring or swelling. It can further help in determining other conditions like astigmatism. Generally, this test performed before surgery like a cornea transplant or contact lens fitting.
5. Retinoscopy Is Another One:
There are times when you might be asked to look right into thick instruments with various dials and lenses once you visit the chamber of an ophthalmologist. This machine is called phoropter, and this is used for conducting a retinoscopy. This machine helps the optometrist to approximate the present optimal lens prescription. As you get the chance to gaze through the machine, the doctor will flip multiple lenses in front of the eyes for an eye test. The focus will be on a prominent object. The doctor will shine light into eyes and watches how that affects the eyes with multiple lenses before coming to a conclusion.
The reliable doctors will be the one given chance to perform the eye test on patients. The doctors will use four types of charts to determine the test and those are Snellen, Tumbling E, Landolt C, and ETDRS. You can rely on them completely for accurate results.
