These are awesome. Ever have those jobs that require some focus? Threading a needle. Tying a fly. Building a boat in a bottle. Whatever, these let you zoom in 2.75x, keeping your hands free. So it’s full 3D magnification. You can adjust each of the eyepieces and they re-adjust coloration to ensure that you get a clear view of the mosquito you are dissecting for scientific purposes. Or whatever.
Could be a great gift for the crafty person in your life.
Did we mention they look a little steampunk-ish. Yeah. We like that.
