Routine eye exams are used to detect many eye conditions, including:
Eye Exam Tests
Some of the most common eye exam tests include:
Eye muscle movement test: The provider asks the patient to
follow a specific object, such as a light or pen, with their eyes. This test
is done to ensure the eyes are aligned correctly and that there is no damage
to each eye muscle.
Cover test: Here, the patient looks at an object first with
both eyes, then with each eye individually. This determines whether or not
the eyes are working well together, or if there’s a vision problem in
just one eye.
External exam: During this test, the doctor holds up a
light to each eye close and at a distance in order to see how the pupils
Visual acuity test: This is also known as a
chart test and is perhaps the most famous part of the eye
exam. Here, the patient reads a letter chart at a distance. The letters on
the chart get progressively smaller, providing a simple analysis of the
patient’s overall vision.
Retinoscopy: This test is done with a large machine known
as a retinoscope, which cycles through various lenses.
These lenses test the light refraction in each eye.
Refraction testing: This can also be performed using a
retinoscope, and is often done to fine-tune a specific glasses or contacts
prescription. This test cycles back and forth between two lenses to
determine which is better for the patient.
