Does using your hands as binoculars work?

It’s very simple: Make a tiny hole with your finger (curling up index finger works best) and look through it. Whatever you’re viewing, be it text, object or vista should appear considerably clearer. It is hardly a replacement for corrective optical devices but a pleasing 20-second time waster all the same.

Why do hand binoculars work?

Similar to other primates, our brains are designed to work with binocular vision. The word binocular comes from the Latin words bini (meaning double) and oculus (meaning eye). However, the brain merges the two images into one and gives the illusion that there is a hole in your hand.

Why can I see better when I cup my eyes?

When we squint it creates the same effect as looking through a pinhole. Basically only a small amount of focused central light rays are allowed into the eye. This prevents the unfocused light rays in the periphery from reaching the retina. The result is better vision.

Why do I see a hole in my hand?
