Mirrored lenses will reflect whatever they “see,” so the goal is to make them see something large, bright, and clean rather than your room or camera.

A good approach is to surround the sunglasses with diffusion: use a small light tent, or build a white box/cavity from white cloth, paper, or styrofoam, then light the outside of that tent/box. Shoot through a small hole for the lens. This creates very soft, non-directional light and greatly reduces hard reflections.

For a flat lay, also place large white paper or cards close to the lenses so the lenses reflect white instead of clutter. Move the paper around until the unwanted reflections disappear.

A circular polarizer on the camera can also help reduce some reflections and may help reveal the lens color more clearly. Rotate it while watching the effect.

If reflections still remain, adjust the angle of the glasses, camera, and white fill surfaces slightly. Small changes in angle can make a big difference with reflective products.
