Which frame measurement is also known as eye size?

• A. Eye size
• B. Bridge width
• C. Temple length
• D. Lens height

Answer: (A)

Eye size is the horizontal width of one lens, the dimension that defines how wide the opening in the frame is across the eyes. This measurement is often called the lens width, and that same term is simply another name for eye size. Knowing this helps you understand fit and how much of the frame surrounds each eye. The other measurements refer to different parts: bridge width is the distance across the nose between the lenses, temple length is how long the arms are that go behind the ears, and lens height is the vertical size of each lens. So the measurement that is also known as eye size is the width of one lens.
