How to find your dominant eye

Follow these steps:

1) Extend your arms in front of you and create a triangular opening between your thumbs and pointer fingers by placing them together.

2) With both of your eyes open, center this triangle on a distant object, like a clock or picture frame.

3) Close your left eye.

4) If the object stays centered when your left eye is closed, then your right eye (the eye that is open) is your dominant eye. If the object is no longer framed by the triangular opening, your left eye is your dominant eye.
