Blended Vision (aka Mini-Monovision) The goal of blended vision is to allow you to see without glasses at both distance and up close by setting the focus of one eye for distance and the other eye for near.
A single vision or as it sometimes is called tunnel vision can mean that you are only looking or focusing on one thing at a time. Many people have single vision when working. Edit
