Which practice helps ensure proper alignment and centration of soft lenses during fitting?

• A. Center the lens with a blink and verify comfort.
• B. Place the lens on top of the eyelid
• C. Use suction reposition
• D. Blink not required

Answer: (A)

Centering soft lenses relies on the lids doing the work as the eye blinks. When a lens is placed on the eye, a natural blink helps the upper and lower lids settle the lens evenly over the cornea, promoting proper alignment and centration. After insertion, you want to verify comfort and confirm that the lens is centered and moves appropriately with some blink or gaze movement. If the lens is decentered or uncomfortable, you’d reassess the fit rather than rely on repositioning methods that don’t involve the natural settling action of the lids. Placing the lens on top of the eyelid isn’t how a proper fit is achieved, suction reposition isn’t standard practice for soft lenses, and blinking is indeed required to center the lens properly. Centering with a blink and verifying comfort is the best approach.
