I too have the problem of the eye's not seeing so well up close (the distance needed to actually see the line properly) and the low light, well, I've got one ot these headlamps, (the New generation type, not the parafin models we used to use when the fastest moving vehicle was a six horse cart).....
I think I must invent someting with a picking needle, a LED light, and magnifying glasses for the job? Patent it and sell it to the fishermen that has to have all the gear, and to the fellow not so good eyed fishermen like us, I'll give it to them for free, but strict testing will be done.......hehehe.
