I've hardly tried them on. I have a blue light block test and they failed. This is the third time I have ordered blue light bifocals (various brands) only to find that they do NOT block blue light. I'm confident your glasses aren't blocking blue light if they don't come with a test lamp and colored strip. They were packed in a thin white box, intact, with a cleaning cloth and 2 vinyl cases (1 black, 1 brown) for glasses. I gave them two stars because they are comfortable and cute and at least at the moment I tried them the bifocal magnification seemed obvious but in the end I didn't get what I thought I was buying. I will return this product.
