What observation might indicate a contact lens is improperly fitted during wear?

The observation indicating that a contact lens is improperly fitted is when vision only clears after blinking. This situation suggests that the lens may not be positioned correctly on the cornea, leading to inconsistent focus until the natural action of blinking redistributes tears and clears any debris or irregularities that might be interfering with vision.

When blinks happen, they help refresh the tear film on the lens surface, making it possible to see clearly momentarily. If a lens fits well, it should provide consistent and clear vision without the need for such corrective actions as blinking to achieve clarity. If this condition is frequently experienced, it indicates a need for reassessment of the lens fit or prescription.

Observations such as consistent clear vision, frequent adjustments needed, and comfort throughout the day would typically suggest that the lens is fitting well and functioning as intended, without issues impacting visual clarity or comfort.
