Works as it should but the yellow tint of the lenses is more eyestrain than without them. Zoom is ok, but I just don't see any benefit from the "blue light filter". It comes with a nice protective case and a cleaning cloth - awesome! Unfortunately, I only had to give 4 instead of 5 stars because of the yellow cast. It actually worries me a lot and just makes my eyes more tired than regular reading glasses. Otherwise the quality is pretty good for the price.
