Not everyone has them, but everyone who wears glasses should think about getting a second pair – and not just because it's trendy and can help change your look. You can quickly reach for a second pair of eyeglasses when you can't find your other pair. A second pair of eyeglasses can be a lifesaver in an emergency, especially for those with very poor vision.
