What could excessive movement of a soft contact lens suggest?

Excessive movement of a soft contact lens typically indicates a poor lens fit. When a lens is fitting properly, it should move with the natural blink of the eye but should not shift excessively. This movement could suggest that the lens is too loose or not centered properly on the cornea, which can lead to discomfort, blurred vision, and irritation. Poor fit can also increase the risk of complications such as corneal abrasion or complications associated with poor ocular health.

In contrast, good lens fit would result in minimal movement, as a well-fitted lens aligns more closely with the contours of the eye. Similarly, healthy corneal response and optimal moisture retention would not correlate with excessive lens movement, as these conditions generally reflect a well-fitted lens that creates a stable environment on the eye. Therefore, the presence of excessive lens movement is a clear indicator of a poor lens fit.
