Definitely not as advertised
I purchased these spectacles thinking they would be photochromatic with blue light blocking and auto focus but all I got was a pair of standard reading glasses which are much better than my varifocals for reading as they magnify. So I'm not overly disappointed but I could have bought a pair cheaper from anywhere that sells reading glasses. I would say don't be taken in by their advertising go to your local thrift store for a similar product.
