I have found out how to enlarge the font on mudcat forum so even if i can't find my spec-a-ta-cles i can still read it!
I don't remember how i did it, but it has really helped.

I also keep straps, or eyeglass keepers on glasses and sunglasses,
so i can wear them around my neck if not usingthem.

One brand is Croakies, http://www.croakies.com/
another is Chums--http://www.chums.com/

there are often glasses "keepers" in grocery stores,
and the chains and beaded ones may look dorky, but
not half as dorky as you will look when squinting
and straining to see.

many are made from neoprene...like skin diving suits..
