HA, glasses! What bothers me. I look for them more often than I clean. I have several, reading 1.5. Some of them are great, I carry them in a purse in a leather case and I am appropriately proud of them, I have saved for a long time. The others are from a drugstore, made in China. I clean them with a dampened DM pillow, a box of 52 pieces about 35 CZK, but I don't know exactly, it will last half a year. When it comes to cleaning, I take it easy. With one pillow, I'll clean all the dahlia glasses, the phone, the tablet, and the monitor when I remember. :)
