Thrilled (although not entirely surprised) by the success of the original 'Spare Pair' (three pairs are proven to be better than one now), IF USA created a new set with the more book-conscious in mind. Still with three pairs of the same dioptre on one card but this time with three different cool frame shapes to change up your 'look' too.
Each set of reading glasses comes with three pairs of different frame styles but the same strength.
