At the age of 54 my eyesight is to say the least not what it was!!!
I found myself struggling to tie flies on and started carrying a pair of reading glasses in my chest pack swapping them on and off when I needed to rerig.
Then I found the "Flip Focal", eureka moment!!! no more swapping glasses, just flip them down and ive got instant 2.5X magnification meaning I can see again!!! its almost a miracle!!!!
When not in use they fold up out of the way and you don't even notice that they are attached to your cap, a strong pin and clip attachment means there is no risk of you losing them either (unlike glasses!!!! lol)
