When positioning adjustable nose pads, how should they appear from the side?

When positioning adjustable nose pads, they should appear vertical from the side. This positioning is crucial for both comfort and proper fit of the eyewear. Vertical nose pads help ensure that the frame sits correctly on the nose, providing stability and preventing the glasses from sliding down. This alignment also helps distribute the weight of the lenses evenly across the bridge of the nose, which can enhance overall wearability and reduce pressure points that may cause discomfort.

In contrast, horizontal, diagonal, or canted positions would not provide the most effective support or comfort. Horizontal pads may not anchor the frame effectively, while diagonal or canted positions can lead to improper alignment of the lenses, potentially causing visual distortions and discomfort for the wearer. Thus, maintaining a vertical orientation of the nose pads is essential in optimizing the fit and function of the glasses.
