Neanderthal

I got 2 pair of noblu glasses , they came today. My prescription glasses correct near and far vision. I took my prescription glasses off and put on a noblu glasses on. I tried to read with them some things my prescription glasses would let me read , with the noblu glasses I could barely my out the letters. Holding the glasses up from my nose so I could look under them and then though them , to see how much differences there was. The differences was not much. And they did not help with my far foresightedness. They may work for blue light , but that is not of much use if you can not make out what you are looking at. IF they did what they say in the ad they would be good, but they do not magnifies like the film shows. So I would have to say they are not good for the money they cost, So I would advise to not buy unless you only need the blue light blocking option.
