What is the role of the eyewire in eyeglass frames?

1. Connects the bridge to the hinge

2. Surrounds each lens and holds it in place

3. Distributes the weight of the frame on the nose

4. Allows the temples to fold in

The correct answer is: Surrounds each lens and holds it in place

The eyewire plays a critical role in eyeglass frames by surrounding each lens and securely holding it in place. This component is essential for maintaining the lenses' position relative to the wearer's eyes, ensuring proper visual alignment and comfort. A well-constructed eyewire also contributes to the overall durability of the glasses, preventing lenses from becoming dislodged during regular use. Regarding the other options, while they describe other important aspects of eyeglass construction, they do not pertain to the specific function of the eyewire itself. Each part of a frame, such as the bridge or temples, serves a different purpose in the overall structure, but the primary job of the eyewire is indeed to encase and stabilize the lenses.
