What Is a Varifocal Lens?

In Animal Vision

• The lenses in humans' and other animals' eyes flex to shift sharp focus between distances. Bi- and trifocal corrective lenses are properly multifocal, rather than varifocal, meaning the viewer, rather than the lens, does the shifting. Early in 2010, however, the U.S. Food and Drug Administration approved the first "accommodating" lens for implantation after cataract surgery, flexed by eye muscles like a natural varifocal lens

In Photography

• The optical zoom lens on almost every digital camera is varifocal, though it's actually a system of lenses that changes the distance between its components. The long zoom lens that snaps onto an SLR (single-lens reflex) camera, digital or not, is the classic form

In Surveillance Cameras

• Variable focus in a single lens came to security cameras in the 21st century, but is usually set manually: When you set up your surveillance system, you can choose where in its field of view you want each camera to focus. The camera doesn't zoom in on suspicious activity, and you can't refocus recorded video to read a license plate
