I've only had these glasses for a few weeks. They appear to be well made and come with a nice hard case as well as a padded carry case. I don't have the equipment to measure exactly what percentage of blue light they block, but from my rough experimentation at home they appear to be very effective. As for their beneficial effects, if any, it's too early for me to comment.
