If a soft contact lens wearer states their vision is clear only after blinking, what does this indicate?

When a soft contact lens wearer reports that their vision is clear only after blinking, this typically indicates that the lens might be too steep. This occurs because a steeply fitted lens may not achieve optimal alignment with the cornea, leading to an initial build-up of tears between the lens and the cornea after blinking. When the wearer blinks, the eyelids help to reposition the lens or redistributes the tear film over the lens surface, temporarily improving clarity.

In contrast, a loose fit usually results in excessive movement of the lens during blinking, which can cause fluctuating vision rather than a momentary improvement. A proper fit generally provides consistent vision, as the lens sits correctly on the eye without the need for blinking to clarify vision frequently. Lastly, while dry eye could be a factor in visual clarity, it does not directly correlate with the observed pattern of vision improvement upon blinking.
