Xiaomi Mijia Clip-On Polarized Sunglasses 12g Lightweight Compatible with Myopic Glasses Removable Clip-On Uv-Proof Tac Lens

The glass is not attached, but clipped in front of prescription glasses.

Hello, the lens size of our Xiaomi Mijia clip-on sunglasses is 65 mm. We kindly ask you not to purchase this product without comparing its dimensions with your own glasses, as it has a rather large structure. If your eyeglass frame is small or medium size, this attachment may be too large for your frame and might not fit aesthetically well. Before purchasing, I recommend you to do this check: Measure the widest part of your own glasses lens (horizontally) with the help of a ruler. If this measurement is smaller than 65mm, our product will bulge out from your glasses frames. This model is designed specifically for a full fit with glasses, especially with wide glass and large frames. If you are not sure about the fit after taking your measurements, you can write us your glasses measurements and I will be happy to help you with the fit.
