What is a Cover Test?
A cover test is one the simplest ways that an eye doctor does to check how your eyes work together. Such eye exam typically involves unilateral and alternating cover test.
During the unilateral cover test, you will be instructed to focus on a distant object. The eye doctor will cover your right eye with an occluder while observing the movement from the left. The same procedure will be performed but it would be the left eye to be covered this time.
On the other hand, the alternating cover test is done by switching the occluder from one of your eyes to the other.
What is the Purpose of a Cover Test?
Aside from checking how well your eyes work together, a cover test is also done to detect a deviation or misalignment of your eyes. Early detection of eye deviation may prevent you from getting double vision and developing eyesight deficiencies.
How to Prepare for a Cover Test?
Just like the way you prepare for other comprehensive eye exams, you need first to make an appointment with an eye doctor. As much as possible, clearly describe the vision problem you’re experiencing. Discuss, if there is, your family’s eye health history.
