Definition: What Is a Lens?

A lens is a transparent surface, such as a piece of glass or a special type of plastic, that has been specially constructed so that it can disperse or concentrate rays of light. A lens can be concave or convex, depending on the direction it curves. The shape of the curve impacts how light behaves when it passes through the lens.

  • Some objects have just a single lens. Examples include a magnifying glass or camera lens.
  • Some items have multiple lenses. Examples include eyeglasses or binoculars.

Figurative Usage of Lens

The word lens can also be used in a figurative manner. For example, the phrases "through the lens" or "through a lens" are examples of metaphors using this word.

  • Their actions will be judged through the lens of history.
  • Before making a decision based on finances, consider it through an ethical lens.

Used in quotations like the examples above, the word lens doesn't refer to a concrete transparent object. Instead, this usage is treating the word lens as a synonym for words like perspective and angle.

Lense vs. Lens: Why the Confusion?

The word lens is a singular noun. The plural form of this word is lenses. It seems that a misunderstanding about the singular form of this word is likely the primary source of confusion regarding lens vs. lense.

  • Since many common nouns are made plural by adding an "s" to the end of the singular form, people sometimes incorrectly assume that the word lenses is formed by adding an "s" to lense.
  • However, lense is not a word in American English or UK English (or any other language). The correct singular term is the word lens. Since the word lens ends in an "s," an -es is added to the end of the word to convert it to a plural noun.
