Solar Shield Polarized Clip-On Sunglasses vs Serengeti Clip-On Polarized Sunglasses

Buy the Serengeti clip-on if you already own Serengeti Nelson frames or want mineral glass lenses with strong contrast. Buy the Solar Shield if you want a universal clip-on that fits most rectangular frames and costs far less. The Serengeti has the better lens material and build, but it only snaps onto specific frames and is not prescription-friendly. The Solar Shield is plastic, lighter, and more forgiving on fit, but its optics are a step down.

• Choose the Solar Shield if you want a low-cost universal clip-on for any rectangular plastic or metal frame and don't need mineral glass.
• Choose the Serengeti if you own Serengeti Nelson frames or want mineral polarized glass with 555nm contrast for driving.
