How to Test for an Eye Turn at Home (Cover-Uncover Test)
Think both of your eyes are aligned? Let’s find out.
In this video, Dr. Bryce Appelbaum shows you how to do the cover-uncover test to screen for an eye turn also known as Strabismus.
Most people have no idea one eye may drift or that their eyes aren’t coordinating together properly.
When that happens, your visual system compensates and that can show up as:
• Eye strain
• Headaches
• Fatigue
• Double vision (or suppression)
• Poor depth perception
• Trouble with coordination and balance
This quick test helps you check if your eyes are working together efficiently.
⚠️ This is not a diagnosis, but it can help you decide if it’s time to get tested professionally.
