Fitting soft lenses steeper than the K reading typically results in which of the following?

When fitting soft contact lenses that are steeper than the K reading (the keratometry reading, which reflects the curvature of the cornea), fluctuations in vision following a blink can occur. This happens because a steeper lens may not align perfectly with the natural curvature of the cornea. As a result, when a person blinks, the lens can shift slightly on the eye, leading to temporary vision changes or fluctuations as the lens temporarily moves away from its optimal positioning.

Maintaining proper alignment between the lens and the corneal surface is crucial for stable vision, and when the fit is too steep, this stability can be compromised. Over time, the lens may not provide the expected comfort, vision clarity, or overall performance, leading to these visual fluctuations. Understanding this relationship between lens fit and vision stability is key for effective lens fitting practices.
