What type of frame partially exposes the lenses and holds them in place?

• A. Full-rim frame
• B. Semi-rimless frame
• C. Wire frame
• D. Plastic frame

Answer: (B)

The semi-rimless frame is designed to partially expose the lenses, typically holding them in place along the top edge while leaving the bottom edge exposed. This design not only provides a modern aesthetic but also allows for a lighter and often more comfortable option for wearers, as the absence of a full rim can reduce bulk and weight. In addition, this type of frame can lend itself well to a variety of lens shapes, providing versatility in style while maintaining the necessary structural support to hold the lenses securely. Other frame types, such as full-rim frames, enclose the entire lens in a complete frame, providing maximum protection but lacking the exposed lens characteristic. Wire frames offer a minimalist look often with no rim at all, which is different from semi-rimless designs. Plastic frames can be full-rim or semi-rimless, but the defining characteristic of the semi-rimless is that it specifically exposes part of the lens. This feature helps distinguish the semi-rimless frame in the context of lens exposure and support.
