My SIL got her first bifocals a couple months ago and she figured while up town she'd do her errands. W And ell she said she had a headache from h-ll - she was dizzy and once she was out of town she had to pull over to be sick. She now wears her glasses a little lower on her nose while driving so she doesn't ''get caught on the invisable line''---no more headaches or nausea. I do understand the bright eyeglass case. If you was to look inside my purse you'd think I was carrying my own personal rainbow. I can find what ever I need real quick now.
