What should be adjusted if a child's bridge is extremely flat?

When a child's bridge is extremely flat, adjusting the retroscopic angle is crucial. The retroscopic angle refers to the angle at which the lenses tilt backward from the front of the frame. A flat bridge can cause the frames to sit improperly on the child's nose, leading to discomfort and misalignment with the eyes.

By adjusting the retroscopic angle, you can ensure that the lenses align correctly with the child's line of sight. This adjustment helps create a better fit by angling the lenses in a manner that maintains proper visual alignment and enhances comfort. Ensuring the right retroscopic angle can also improve the aesthetics and functionality of the eyewear by ensuring that the lenses are positioned optimally.

Other adjustments, like pantoscopic angle, face form, and X-ing, do have their place in fitting but are not the primary concern when working with a flat bridge in a child's eyewear. Each of these other adjustments pertains to different aspects of lens positioning and frame fit, such as side tilt or curvature of the frame, which might not directly address the issue presented by a flat bridge.
