How can inadequate movement of a soft lens be corrected?

Inadequate movement of a soft contact lens can indeed be addressed by using a lens with a smaller diameter. When a soft lens is too large, it may be more stable on the eye, resulting in insufficient movement with blinking. A smaller diameter lens can allow for more natural movement, as it may be more able to shift slightly with the eyelid during blinking. This movement is important for overall comfort and proper tear exchange beneath the lens, which can enhance wearability and reduce the risk of complications such as discomfort or dryness.

Using a larger diameter lens, on the other hand, tends to increase stability and reduce movement, which is not conducive to correcting inadequate movement. A steeper base curve might also contribute to more snug fitting, further limiting lens movement rather than improving it. Adjusting the water content can influence lens properties such as hydration and oxygen permeability but does not directly address the issue of lens movement. Thus, opting for a smaller diameter soft lens is the most effective means to promote improved movement and comfort.
