Perfect for sport sunglasses
Perfect for sunglasses when you need a bifocal for seeing close-up occasionally.  Sticks well. For me when I bicycle I need to read my speedometer or fix a flat. I trimmed them to about half the size with a razor knife and shaped the bottom to the eyeglass frame.  Take note that they should be placed on the bottom inside corner of the lens, not in the middle.  Saved big $$ for not having to buy sport bifocals again. I wouldn't consider them for normal everyday reading use.
