Is it easy to dunk a pencil with one eye closed as with both eyes open?

Dunking a pencil with one eye closed can be more challenging than with both eyes open due to the loss of depth perception. When using both eyes, the brain merges the images to provide better distance judgment, which helps in aiming accurately. Closing one eye can make it harder to gauge how far away the pencil is, potentially affecting coordination and precision. However, with practice, some individuals may adapt and find it easier to compensate for the loss of depth perception.
