Which statement describes signs that a lens is inverted (inside out)?

• A. Mild discomfort, mild decrease in acuity, excessive lens movement, and flared edges
• B. Excellent comfort with no movement
• C. Lens appears completely opaque
• D. No changes in vision

Answer: (A)

When a soft contact lens is inverted, it doesn’t seat on the eye the way it should because the curvature on the wrong side sits against the cornea. This misfit tends to cause a mild discomfort and even a slight blur, since the tear film and lens aren’t aligning properly to create a stable optical surface. You’ll often see or feel that the lens moves more than normal with blinking, because it isn’t snugly conforming to the eye’s shape. At the edge, the lens can flare outward or lift, making the edges appear prominent or “flared.” Together, these signs—some discomfort, a mild drop in visual sharpness, excessive lens movement, and flared edges—point to the lens being inside-out. A lens that fits well feels comfortable with only normal movement, and vision remains clear; an opaque lens or no change in vision would suggest a different issue.
