What term describes vertical misalignment due to a twisted bridge in eyewear?

The term that best describes vertical misalignment due to a twisted bridge in eyewear is "X-ing." This terminology refers to a specific configuration where the optical axes of the lenses diverge vertically as a result of a misaligned or incorrectly positioned bridge. In this situation, the lenses do not align with the visual axis of the eyes, leading to a condition where images perceived through the lenses appear misaligned.

Understanding this concept is essential in optometry and eyewear fitting, as it highlights the importance of proper lens alignment for visual comfort and clarity. If the bridge of the eyeglasses is twisted, it can cause the lenses to tilt relative to the eyes, resulting in the "X-ing" effect.

The other terms listed like prism, strabismus, and skew refer to different optical or medical conditions that do not specifically denote the issue caused by a twisted bridge in eyewear. "Prism" is a term related to the angle of deviation of light in eyeglasses but does not imply misalignment from the bridge. "Strabismus" is a medical condition concerning eye misalignment but is not caused by eyewear issues. "Skew" can describe certain types of misalignment but does not specifically relate to the effects of a
