Review on Light Blocking Round Glasses Women Computer Accessories & Peripherals by Matthew Fleming

I bought these for my boyfriend who 1) sits at his computer all the time and 2) wants his eyesight to be bad so he can wear glasses (he likes the look). I thought they seemed a little weaker than they looked when I took them out of the box - the plastic feels a bit cheap - but so far they've held up well and he loves them. Obviously the filter works - if you hold it up to a computer screen you can easily see the difference through the lenses. I have prescription glasses with a built in blue light filter and I'm pretty sure they are stronger than the filter on my glasses.
