This Zoom In icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,400 icons, all in the same style and quality.
The icon is a magnifying class with a cross, or plus sign in the middle of the lens. The lens is the largest part of the icon, and the handle faces downward and to the right at a 45 degree angle from the lens.
