Insanely good readers. The 2.50+ lenses are the clearest I have found in 10 years of buying and wasting money on readers that were substandard in materials and inaccurate lens values. For the price I find that remarkable. They really are very very light weight and could be confused for cheaply made but thats not true at all.***UPDATE 4-19-2017*** Well here is the reality to these glasses after having them only 12 days they literally split while wearing them and fell off me. Good thing I wasn't driving. This is cheap junk. For $18 a pair this is the worst pair of readers I have ever owned. See attached photos so you know what to expect.
