When adjusting eyeglasses, what is the function of nose pad pliers?

To tighten screws
To adjust the angle of the lenses
To move and shape the nose pads
To replace the nose pads

The correct answer is: To move and shape the nose pads

The function of nose pad pliers is specifically designed for moving and shaping the nose pads on eyeglasses. These pliers allow the technician or optician to adjust the position and angle of the nose pads, ensuring that the frames fit comfortably and securely on the wearer’s nose. Proper adjustment can help distribute the weight of the glasses evenly, enhancing comfort and preventing slippage, which is crucial for maintaining proper alignment of the lenses for optimal vision. In contrast, tightening screws involves different tools such as a small screwdriver, which is not the primary function of nose pad pliers. Similarly, adjusting the angle of the lenses themselves typically requires different tools or techniques, rather than the pliers intended for nose pads. While replacing nose pads may be part of maintenance, it usually involves a different procedure that may include unscrewing or unclipping the pads and does not fall under the main function of the nose pad pliers.
