Deep-set eyeglass nose pads are nose pads designed to push the frame further away from the face than standard pads. They are specifically used when the wearer has a low nose bridge or high, prominent cheekbones.

By pushing the frame out, deep-set pads stop the lenses from resting on the cheeks, prevent eyelashes from touching the back of the lens, and allow for better air circulation to reduce fogging.
Deep-set pads are an adjustment tool. By changing the vertex distance, they affect the effective power of the lens, especially for high prescriptions. Opticians must account for this increased distance when prescribing the final lens power.
These specialized pads are typically made of hypoallergenic silicone or soft PVC. Silicone is often preferred because its soft, high-friction surface grips the skin better, helping the frames stay positioned despite the increased weight leverage.
This component plays a direct role in the frame's longevity and integrity. The specific design helps the spectacle frame withstand normal wear, resist breaking at stress points, and provides a superior aesthetic finish. Understanding its purpose is for assessing the overall quality and expected lifespan of the backup glasses you rely on.
Deep-set pads are mostly used on metal frames with adjustable pad arms, but sometimes custom plastic frames are designed with built-up, deep-set bridges.
Yes, for high prescriptions, the optician must calculate the final power based on the new, longer vertex distance.
No, the pads must be selected and installed by an optician to ensure they are properly aligned and positioned for correct vision.
Deep-set pads change the "Vertex Distance" (space between eye and lens). If you find your vision is clear only when you push your glasses against your face, your vertex distance is too long. A doctor must verify the power compensation for this gap.
