Blue crystal sunglasses

Try white, navy or denim as a base, then repeat one small detail rather than matching every piece. Compare the finish as well: matte, shiny and translucent or textured surfaces can make the same colour look more or less prominent.

No universal improvement follows from its colour. The external reflection is not a performance specification. Compare the stated filter category, intended use and lens technology; do not assume a yellow, pink or blue finish is suitable for night use.

Use several images of the same variant if available. Lighting and angle can change the visible reflection; also check the colour name and lens features. Do not infer from a photograph how your view through the lens will look.

Do not infer the view through the lens from its outer reflection. Check the lens tint and specifications, which may differ from the colour visible outside.

They can combine these features if stated. Photochromic technology changes tint under specified conditions; a mirrored finish alone does not imply this behaviour.

Tint and ultraviolet protection are different properties. Check the stated protection and filter category; colour alone confirms neither.

Follow the design's instructions, remove dust first and use a clean microfibre cloth. Avoid rubbing with clothing or paper and do not use cleaners without confirmed compatibility.
