"Useful if your eyes are ageing and threading tippet through a tiny eye is becoming challenging."
This is heading into gadgetland. The TyMate combines a pair of 1.5x power magifying lenses with a small LED light unit. The idea is this clips to the brim of my hat, so when I need to tie on a fly I have the power ...magnification power! So far so good. I use fly-tying magnifiers as standard, so adding this to my fishing hat is not a big step. This looks a bit bulky but is light, so having it on my hat is not a big deal. The lenses are on an articulated arm so they can be folded and retracted, safe and sound, into the body of the TyMate. Then deployed, which is fiddly, when needed.
The lenses are high quality and certainly magnify. The little LEDs are bright, I can use them or not. Getting the light and lenses looking at the same thing takes a bit of practice. Useful if your eyes are ageing and threading tippet through a tiny eye is becoming challenging.
