What could a dispenser do if the frame slides down the wearer's nose?

When a frame slides down the wearer's nose, one effective adjustment is to decrease the nose pad width. This alteration brings the pads closer together, improving the contact with the sides of the nose and providing greater stability. As a result, the frame is less likely to slide down during wear.

Other options, such as increasing the nose pad width, would increase the distance between the pads, leading to less stability on the nose and potentially worsening the sliding issue. Loosening the temple screws might affect the fit of the temples but is unlikely to address the problem of the frame slipping down. Increasing temple spread could alter how the frame sits on the head as well, but it typically doesn't resolve the issue of the frame's position on the nose itself. Decreasing the nose pad width directly targets the area causing the slide, making it the most appropriate solution.
