These are flip-up clip-on sunglasses that attach to your own prescription glasses, sold as two pairs in black and brown. The polarized H+D lenses cut glare and carry a UV400 rating, and the anti-reflective coating is meant to ease eyestrain. They suit people who wear myopia or presbyopia glasses and want sun protection without a second pair of prescription shades. Against dedicated prescription sunglasses they are cheaper and swap between frames, but they add bulk and weight to the front of your glasses and the clip fit is not universal.

These Joopin clip-on sunglasses come as 2 pairs, one black and one brown. They suit sports and outdoor activities such as skiing, golf, cycling, running, fishing and driving.
The lenses are polarized (H+D) to help eliminate reflected and scattered glare. They cut glare from sunshine, reflections and other harsh light sources. An anti-reflective coating helps relieve eyestrain. The lenses are UV400 and protect against UVA, UVB and UVC. They also block blue light from electronic screens.
The clip-ons come with a leather case, a polarized test card and a cleaning cloth, for easy storage and carrying.
