Joopin Polarized Clip-On Sunglasses vs Polaroid PLD 6158/CS Clip-On Glasses

The Joopin clip-on is the practical pick for anyone who wants to turn existing glasses into sunglasses cheaply and reversibly. It is a standalone clip with a flip-up hinge, TAC polarized lenses rated UV400, and a light plastic-and-metal rimless frame. The Polaroid PLD 6158/CS is a complete prescription-ready frame with a matching clip-on, steel construction, and Polaroid's own polarized lens heritage. Reviewers of the Joopin praise the fit over prescription frames and the flip-up for reading a phone; the Polaroid is the sturdier, more finished product for someone buying new glasses rather than adding to old ones.

• Choose the Joopin if you already wear prescription glasses and want a light, flip-up polarized clip that stores in a small case.
• Choose the Polaroid if you are ordering new prescription glasses and want a steel frame with a factory-matched clip-on.
