Clear or lightly tinted plastic, allowing skin and hair tone to show through around the frame.

Rimless styles carry the least visual weight of any eyewear option, since only the thin bridge and temple pieces show — worth knowing if a genuinely understated look near the face is the goal.
This is a rimless design (no surrounding frame material at all around the lenses), the closest verified example to a transparent/clear frame — a true clear acetate frame is a related but visually distinct style.Photo: “Rimless glasses” by Sciencia58, CC BY-SA 4.0, via Wikimedia Commons.
One of the lowest-prominence options — designed to recede rather than stand out.
A common choice for a soft, understated look that doesn't compete with the rest of an outfit.
Minimal interaction, since the frame itself carries little colour.

A clear frame transmits most of the light that enters it, so its colour is mostly borrowed: skin, hair and background show through the plastic, faintly tinted and slightly blurred. The edges are where it does show — light bends and reflects inside the thick rim, so outlines and polished faces pick up bright lines while the middle stays see-through. The result is the lowest lightness contrast of any frame, which is why it recedes; a very slight tint of grey, pink or champagne is enough to shift that borrowed colour.
The material: Crystal acetate and clear injection-moulded plastics can slowly yellow with long exposure to light and skin oils, which makes an originally water-clear frame read warmer over time.
