I have 2 blue light blocking glasses, these and a more expensive one ($14 at Walmart so not that expensive). Pros: They're lightweight, reduce eye strain, don't slip off your nose, and are very affordable. They fit my small face well. Cons: They leave the skin behind the ears sore after about 30 minutes of wear and don't block blue light like my "more expensive" pair. Given the price, it's still a pretty good deal, especially if you only need them for light use (instead of an 8-hour workday). Recommend!
