To check the bridge size for a frame, which action should be taken?

To check the bridge size for a frame, lifting the frame slightly and observing the space between the bridge and the sides of the nose is an effective method. This practice allows the practitioner to assess how well the bridge of the eyewear fits against the contours of the nose. A proper fit should ensure that the frame rests comfortably without pinching or creating excessive space, which could lead to discomfort or misalignment in vision.

When the bridge fits correctly, it should sit snugly against the nose without any significant gaps or pressure points. Observing this space helps determine if the bridge width is appropriate for the client's nasal structure. If there's too much space or if the frame feels loose, it may indicate that the bridge size is too wide, which could affect the overall fit and stability of the glasses.

This method effectively provides insight into the suitability of the frame for the wearer, ensuring that they receive the best possible comfort and optical performance from their eyewear.
