I wear my reading glasses to sew (and read) and my computer glasses for pretty much anything else in the house except watching the larger TV (which is rare). I hardly ever wear my regular distances glasses because I can't see up close and it bothers me to have blurry food. And if I'm outside I usually have the prescription sunglasses on unless I'm out after dark. Strangely, I can still read my phone without any glasses at all. For most reading I use the Kindle with large font and no glasses.
I tried trifocals once and hated them so I continue to deal with four different pairs of glasses.
