Which bridge shape is beneficial for enhancing visibility in those with shorter noses?

The keyhole bridge is specifically designed to enhance visibility for individuals with shorter noses. This bridge shape features a cut-out section in its center, allowing the eyewear to rest more comfortably and securely on the user's nose without obstructing their field of vision. By redistributing the weight of the glasses and adjusting their position, the keyhole bridge ensures that the lenses are appropriately aligned with the eyes, which is critical for optimal sight. This design is particularly advantageous for people with shorter noses, as it minimizes the risk of the glasses being pushed too far down, which can happen with other bridge styles.

In contrast, other bridge designs may not provide the same level of visibility enhancement for shorter nasal structures. For instance, the comfort bridge can offer a snug fit but may not specifically address the visibility concerns associated with shorter noses, while the saddle bridge and strap bridge also have different mechanisms of support that might not facilitate the best view in these cases.
