Clear vs. Opaque: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Clear refers to materials or substances that allow light to pass through without obstruction, while opaque means not transmitting light.
Key Differences
Clear materials allow light to pass through, enabling visibility through them. Opaque materials, conversely, do not permit light to pass, blocking visibility.

In a clear substance, objects on the other side are visible, as in a clear glass window. An opaque substance, like a wooden door, prevents seeing through it.

Clarity is often associated with transparency and translucency, where light transmission is unimpeded. Opaqueness indicates a complete or near-total blockage of light.

The concept of clear is used metaphorically to describe lucidity in communication or thought, whereas opaque can metaphorically describe something that is difficult to understand or interpret.

Clear substances are essential in optics, like lenses and windows, for clear vision. Opaque materials are used where light blockage is necessary, like in walls and certain coverings.
