I don't love bifocals but they're the best solution for some situations (for me). I have prescription reading glasses and while they work well they make it impossible to do any tasks that are more than six week away. My distance script is nearly 5 cylinder power so pretty nearsighted! I can't do much without glasses which is one reason I have at least twenty pairs (20!) on hand. I keep them stashed all over; one pair in my work knife case, two pairs in the Subaru, one pair in my largest survival kit, etc.
