Hi all,
I've found that as I get older (I'll be 63 this week) I find it harder to see small objects clearly. [Thanks for the link on that great little needle threader from Lee Valley!
I already use an "Optivisor" and a Varilux task light, but it doesn't really light up the area under the needle because my head will be in the way. It's especially difficult to see what I'm doing when I want a nice, close and even topstich attaching a cuff to a sleeve on a shirt.
I found this little light, and just used it. It's really small, smaller than it looks in the picture, and puts out a lot of white, bright light exactly where I want it. Now I can sew a 1/16th inch topstich!!!!
