The magnifying glass: the universal search icon

The magnifying glass is arguably the single most universally understood icon in software. Show one anywhere and users know: type here to find something.

Why it works

A magnifier is a real-world tool for looking closely and finding detail — a perfect, literal metaphor for search. It required almost no learning when it appeared, and decades of consistent use have cemented it globally.

Which way should it face?

Convention points the handle to the bottom-right (lens upper-left). It's not a rule, but consistency with the norm avoids the icon looking subtly “off.” Mirror it only for right-to-left layouts if your system does that systematically.

Search vs zoom

The same magnifier sometimes means “zoom.” Disambiguate with context or a modifier — a plus/minus inside the lens for zoom, a plain lens (or lens + field) for search.
