If one eyewire sits closer to the wearer's face than the other, which adjustment is commonly used?

• A. Equalize the endpiece bends
• B. Increase lens thickness
• C. Narrow the bridge
• D. Tighten temple screws

Answer: (A)

When the frame front isn’t sitting evenly, the first fix is equalizing the endpiece bends. The endpieces link the frame front to the temples, and small adjustments to these bends change the angle and position of the front relative to each eye. By bending the endpieces more symmetrically, you bring the entire front square to the face, so both eyewires sit at similar distances from the face and the lenses align with the pupils.

After making the bend adjustments, recheck the fit with the wearer looking straight ahead to ensure the frame front remains parallel to the face and both eyes are centered. The other options don’t address side-to-side frame alignment: tightening temple screws only affects looseness, narrowing the bridge changes nose placement, and increasing lens thickness doesn’t affect how the frame sits on the face.
