Are both of my eyes equally dominant?

For various reasons, I have been thinking about eye dominance recently. I’ve tried an eye dominance test (form a triangle with my hands and focus on a distant object). The results have always been confusing. Whenever I looked at a distant object, I saw two transparent copies of my hands. I couldn’t really put the distant object inside of the triangle, because there were two triangles. In the reverse fashion, focusing on a close object creates two copies of the distant object. Both the left and right “copies” are equally visible.

These double-vision effects have been obvious to me for my whole life.

One person has mentioned that both eyes may be equally dominant. Is this a possibility?
