What should be checked if the wearer complains of unequal seg heights?

• A. Adjust the temple angles until the segs are equal
• B. Make the glasses over
• C. Check for X-ing
• D. Increase the pantoscopic tilt

Answer: (C)

When a wearer complains of unequal segment heights in their glasses, it is crucial to determine the cause of the discrepancy, and checking for “X-ing” refers to examining whether the frames may be improperly aligned due to the way the lenses are mounted in the frames or the fit of the frames on the wearer's face. "X-ing" indicates that there might be a tilt or misalignment of the lenses, which can lead to unequal seg heights. By ensuring that the lenses are properly aligned and mounted correctly within the frames, you can achieve equal segment heights. This is especially important because it directly affects the optical performance and comfort for the wearer, particularly if they rely on the segments for near vision tasks. In contrast, adjusting temple angles or increasing pantoscopic tilt may not directly address the root cause of the unequal heights. Additionally, remaking the glasses can be excessive if a simple alignment issue is responsible for the unequal seg heights. Therefore, checking for “X-ing” is a foundational step before considering other adjustments or actions.
