Joopin Polarized Clip-On Sunglasses vs Joopin Polarized Clip-On Flip Up Sunglasses

Both are Joopin polarized clip-ons with flip-up lenses, UV400 protection and anti-reflective coating, so the lens experience is close. The single-pair version (A) adds a leather case, a larger 2.2 x 1.3 inch lens for fuller coverage and a flexible rimless frame, and its small set of ratings is very positive. The two-pair version (B) gives you a spare set in black and silver and has far more ratings behind it, though its average is slightly lower. Buy A for one well-covered pair with a proper case; buy B if you want a backup pair or two frame colors.

• Choose the Joopin single clip-on if you want one pair with a larger lens, a leather case and a flexible rimless frame.
• Choose the Joopin 2-pair clip-on if you want a spare set and two frame colors for the same kind of lens.
