Only one issue...
The view through these readers is great.  I don't know if they actually block blue light, but hope that they do.  They are comfortable when I am just sitting. BUT... I have a habit of putting my glasses up on my head, when I get up to do things. One slight bend forward and they try to fall off and usually land back on my nose.  If I bend over to get my dog's water dish...forget it...they fall off my head and on occasion, have gone into the dish.  So unlike my old glasses, I can't easily keep them with me.
