Optical Illusion Smoothing Oil

What you are looking at is Optical Illusion Smoothing Oil by R+Co Bleu, a pair of frames. Frames are bought on fit as much as looks: the three numbers printed on the arm — lens width, bridge, arm length — decide whether they sit right. Take them on and off with both hands — one-handed does more than anything else to pull a frame out of alignment. Discounted listings come and go, and rarely at the same shop twice. Clean with lens spray and a microfibre cloth, and keep them in a case — coatings scratch more easily than the lens beneath them. The best deal and the cheapest sticker price are not always the same listing once delivery is counted.
