#1489: DoubLens

The vast majority of contact lens wearers use two identical lenses.

Today’s invention is a way to reduce the huge amount of waste packaging associated with these valuable articles.

It simply involves placing two lenses into each fluid filled container instead of one, when lenses are being packed in the factory.

Such double lens packs would be differentiated by eg a different coloured foil lid.

There is even an argument for doing this with all lenses so that someone who needs +1.0 and +1.5 dioptre lenses would get one package with 2*+1.0 and one package with 2*+1.5 (since the cost of two lenses can’t be that much more than that for one).
