Yes, but...
For the price, this pair of glasses is pretty decent. It's a bit too big, though, and the reflections are very present, which can be annoying when there's indirect lighting in the room. It's not worth more than 10e for me, including shipping. As for filtering out blue, yes, it's effective without altering the overall tone of the image too much.
It does the job, but the perception of price is very relative to a perceived overall state of expenditure, individually in one's place of residence...
