Which lens mounting attaches separate bridge and temples to the lenses using screws or clamps?

The lens mounting that attaches separate bridge and temples to the lenses using screws or clamps is known as rimless mounting. In this design, the lenses are typically held in place by a series of small screws or clamps that connect directly to the lenses, allowing for a clean and unobstructed look without a full frame surrounding them. This has the advantage of being lightweight and offering greater visual access.

Other mounting styles, such as semi-rimless and Numont, have distinct characteristics that do not match the description provided. In semi-rimless mounting, the lenses are only partially framed, with the lower portion left open, while still using some type of frame that holds the lenses in place. Numont mounting features a bridge that attaches to the lenses but is characterized by a specific design that doesn't adhere strictly to the definition of attaching with screws or clamps for all components.

Understanding the difference in mounting styles is crucial for dispensing opticians when it comes to offers options tailored to the aesthetic choices and needs of the patient.
