I have blue light blocking readers I purchased on amazon for $20 and they are very good. I did buy a set from Prive Receaux on their website with 20% off and they are much better quality. I have bought many cheap readers (not blue light blocking) at various cheap stores and they are not the same quality

The 3.5 refers to the strength of magnification not the size.
