Inserting a contact lens with the concave and convex orientations reversed generally results in immediate discomfort. The altered curvature disrupts the intended fit against the cornea, leading to a sensation often described as feeling like something is present in the eye. Vision may also be temporarily blurred due to the incorrect lens positioning relative to the pupil.
Proper contact lens fit is essential for maintaining corneal health and optimal visual acuity. An incorrectly oriented lens may not only cause immediate irritation but could also contribute to long-term problems if consistently used in that manner. Recognizing the correct orientation of a lens prior to insertion mitigates these risks, ensuring both comfort and effective vision correction.
