For many people, an eye exam means an eye chart mounted on the wall. Even though that is one of the most popular tools to evaluate the functioning of your eyes, some other kinds also exist.
There are basic evaluations to check vision problems, and then there are microscopic examinations to see how different parts of your eyes work together. Each of these eye tests is important for your eye doctor to understand the nature of your vision problems.
Let us now help you with information about the common types of eye tests so that you know what to expect when you arrive at Image Optical in Brampton.
- Visual Acuity Exam
Most individuals would have gone through this test. It is the first type of test that comes to mind when we think about an optometrist near me. The test requires you to read letters from a hand-held card or a screen placed at a particular distance from you. You use one eye at a time to read the letters. Based on your responses, the optometrist learns of the level of the eye’s vision and compares it to the standard 20/20 vision. Besides, the doctor gathers inputs to determine other tests to perform.
As you think of an eye appointment, you see yourself looking through an instrument that has numerous dials and lenses. This instrument or equipment is known as phoropter and is used by the optometrist to conduct retinoscopy.
The results of retinoscopy let an optometrist prepare your optimal lens prescription. During the examination, the doctor changes different lenses in front of your eyes as you look into the phoropter and gaze at a particular object. Generally, it is the first ‘E’ in the eye chart. The eye doctor then uses an instrument to shine a light into your eyes. Depending on its effect on your eyes with different lenses, recordings are made.
- Refraction Exam
A refraction test, in combination with a retinoscopy, is performed to determine the need for prescription glasses. During the test, you look into the phoropter to read the letters on the sign mounted on the wall.
As the test proceeds, the doctor tries different pairs of lenses and asks you with which two lens options you can see clearly. After you respond, the eye doctor decides the protocols for vision correction. He or she also decides what you are suffering from – farsightedness, nearsightedness or astigmatism.
The purpose of this test is to measure the shape of the cornea. The shape of the cornea determines how your eyes perceive and reflect light. In certain people, corneas have elongated or steep curves, resulting in a common vision problem called astigmatism. Keratometry tests are specifically used to determine the existence of astigmatism.
When a keratometry test is performed, the patient looks into a specific machine. This machine is adjusted as per your face so that it is in alignment with your eye. After the test is completed, the eye doctor reads the measurements of the machine to determine the shape of your cornea.
- Peripheral Visual Field Exam
Eyes allow you to look at whatever you can see directly, but you can also view objects on the sides. This entire area of vision is called peripheral vision. The peripheral visual field test evaluates our peripheral vision.
There are different kinds of peripheral visual field tests. These include:
- Tangent screen exam: In this eye exam, you pay attention to a target in the centre of the screen. The optometrist keeps moving objects in and out of the peripheral vision. The patient informs when an object appears and when it vanishes from the peripheral vision.
- Automated perimetry: The patient gazes into a special machine and focuses on a spot in the centre. Every time a light flash appears in the peripheral vision, the patient presses a button.
- Confrontation visual field exam: The optometrist sits opposite the patient and then moves his or her hand out and into the patient’s peripheral vision. When the patient sees the hand, they inform the doctor and also share the number of open fingers in the eye doctor’s hands.
Every test lets an optometrist detect gaps in the patients’ peripheral vision and measure the span of their visual field.
- Intraocular Pressure Management
The fluid in your eyes creates pressure or force. If the pressure in your eyes is of an irregular level, it is a sign indicating the chances of glaucoma.
For a glaucoma test, a machine sends a puff of air when your eye is open. Since the puff of air creates a moment of surprise, your eye’s instant reaction is closing. The machine measures the pressure of your eye depending on your reaction and the resistance of your eyes to the pressure created by the puff of air.
In certain cases, the optometrist can choose to go for a manual intraocular pressure management test. A manual test generally provides a more precise reading. With a special instrument, the optometrist gently touches your eye to record internal pressure. The test begins with the optometrist putting anaesthetic eye drops so that you are not uncomfortable with the instruments.
