Which is your dominant eye?  Here’s a simple test:

Extend your hands in front of your face. Place them together to form a small, triangular opening with your thumbs at the bottom. Using both eyes, look through the opening and focus on a distant object. Maintain your focus on that distant object.  Now close one eye. If the object disappears from the opening, your closed eye is dominant. If it remains, your open eye is dominant.

In package: One sheet of 20 colored dots, 4 grey dots plus 2 grey rectangular strips – see product image.
