01 · EAR HEIGHT
The ears may not be at the same height
If one ear is slightly higher or lower, the temple support point changes.
Even identical temple angles can make one side of the front sit higher or lower, so ear height is a common factor in apparent tilt.
Unequal ear height is one possible contributor to frame tilt, but it does not mean the frame should simply be tilted by the same amount in the opposite direction. Nose support and the route of each temple also affect the final position. Adjust to the worn result, lens height, and pressure distribution, accepting that correctly fitted left and right temples may not look identical off the face.
02 · NOSE POSITION
The nose center and left-right shape may also be asymmetric
A slightly deviated nose or different bridge shape on each side can influence frame centering.
Metal frames may allow some compensation through independent nose-pad adjustment, while plastic frames depend more on bridge design and fit.
Nasal asymmetry can influence both horizontal centering and how close each lens sits to the face. Metal frames offer more independent control through the pad arms, while a fixed bridge has less adjustment range and therefore depends more on structural fit. In either case, do not judge success only by whether the frame looks centered; compare left-right vertex relationship and contact pressure as well.
03 · CHEEKBONE
Cheekbone height and projection can differ
A higher or more prominent cheekbone on one side can create unequal interference with the lower frame.
This becomes more noticeable with large frames or frames worn close to the cheeks.
04 · FACE WIDTH
The two sides of the head are not always identical either
If one temple area is more prominent, left-right side pressure can differ.
That pressure difference can affect frame position and comfort, so simply leveling the front does not solve every asymmetry.
05 · FITTING GOAL
The goal is not to make every frame part identical
After fitting, the two nose pads or temples may look slightly different and still be correct.
An asymmetric face may require small asymmetric adjustments to produce a balanced result.
Comfort, stable lens position and a natural visual appearance on the wearer are more important than bench-top symmetry.
The fitting goal for an asymmetric face is not to make the face appear artificially symmetric. It is to keep each lens in a stable position in front of the corresponding eye, avoid excessive pressure on the nose and ears, and reduce an objectionable visual tilt. With progressive or individually optimized lenses, large cosmetic compensations should also be checked against the wearing conditions used for measurement and ordering.

CAUTION
Do not try to eliminate facial asymmetry
The purpose of fitting is not to make the wearer’s face symmetrical. The goal is a comfortable frame with stable lens position and a visually natural result.
