Review on JOSCHOO 2 Pack Reading Glasses: Blue Light Blocking Eyeglasses for Men and Women - Alleviate Eyestrain, UV Ray, and Glare on Computer Screens by Gerald Mcrae

I see negative reviews from people who seem to have a slightly distorted idea of what reading glasses are for and when to wear them. Here's my experience so far: These readers make it easy for me to read the fine print and watch videos on my 10-inch tablet/laptop screens, and provide some mitigation of the "blue light" coming off those screens (yes, an amber tint) noticeable, especially on a white background, but in no way obscures my view of what's in front of me). Hinges at the temples automatically adjust to accommodate a head width of approximately 4" to 11". When I wear them this measurement is about 5 inches on my head. To give you an idea of this measurement, you should know that I wear a medium sized hat. It's hard for me to imagine that these glasses would cause problems for the average buyer in terms of fit. My 2 pairs have arrived, each with an individual blue/grey hard case (zipped) and a black soft case and cleaning cloth. win win The question of whether you should expect "blue lights" doesn't really bother me. They seem to do what they say but I didn't buy them for that reason. I wanted the tortoise shell plastic framed readers to look budget and fit the bill.
