SPUDZ Classic Microfiber Lens Cleaner – Clip-On Pouch, Washable – for Binoculars, Scopes, Glasses, Screens | Stealth Bronze, 6 x 6 Inch

I get so fed up needing a cloth to clean my glasses all the time whilst I'm out; that this little self-protecting cloth is perfect. The microfibre actually makes cleaning them easy (unlike a tissue or jumper that I normally use) and being able to store it away from dirt afterwards is excellent. I appreciate that this is probably for camera lenses, but it's much more use for my glasses.

These are nice an compact lens cleaners. I used them for both camera and spectacles. Being able to tuck them into the pouch keeps them both clean and compact. They are very expensive, though.

Quality is arguably better on the knock off ones, so just buy whichever is cheaper
