If you've been around the world of prescription glasses, you may be confused on what the difference is between single and distance vision. Let's briefly break down the differences.
Single vs. Distance Vision
In the video below, Eyeglass Tyler compares single vision and distance vision, points out the differences, and discusses what it may mean to you. Read on to learn more!
Single vision corrects for a single focal length. This means your glasses can be used for activities requiring you to be able to see things far away, like driving or walking. You may also need something like reading glasses, which help you see things close to your face. Computer glasses can also correct for an intermediate distance.
Whatever you use your glasses for, single vision will only correct for one distance.
Distance vision specifically refers to distance correction. A subset of single vision, it's the distance type of a single vision lens.
Tyler points out that it's possible to confuse distance vision with the distance portion of a multifocal lens, but most commonly it's mixed up with single vision. These lenses correct distances of 20 feet and beyond, which is where "20/20" comes from. Simple as that!
