I wanted a good quality pair of reading glasses. I was tired of the $5 Wallymart specials. After much research I settled on this brand and the thing that I noticed immediately... Crystal clear vision. The difference between these glasses and the run of the mill cheap reading glasses is huge! These are the real deal.The glasses have a metal frame and spring loaded hinges. The nose bridge has very comfortable pieces molded into the frames verses the wire and pad pieces on other glasses that tend to break off and constantly need adjusting. These glasses fit very well and they tend to stay put on my face much better than other glasses I've used.The lenses are higher quality and it shows. I've used these for several days... literally 4 - 6 hours of use pretty much non stop.... I've noticed zero eye fatigue. I have never used "blue blocking" lenses but I have to say I think it's not a marketing line... many hours in front of a computer and no headache or eye strain even using a stronger 2.5 version.I will 100% buy another pair to keep at work. No more $5 readers for me!!
