If keratometric miers are only clear when the wearer blinks, what can be inferred about the lens fit?

When keratometric mires are only clear during blinking, it typically indicates that the lens is not providing stable vision in its resting position. A lens that is too steep can create excessive apical clearance in the center, which can lead to misalignment with the cornea when the eye is at rest.

During a blink, the lens may shift slightly, allowing for a momentary alignment that brings the keratometric mires into focus. However, when the eye is not in motion, the steepness of the lens can prevent it from resting appropriately against the cornea. This lack of alignment can distort the vision when the eye is still.

Therefore, when observing this behavior with the keratometric mires, it indicates that the lens fit may indeed be too steep, requiring adjustments to achieve a better alignment with the corneal curvature for optimal vision stability.
