Comments about ‘Interchangeable magnetic lenses make 'Switch'-ing easy’

Novel idea! Excellent article.

If they switch out so easily with a little lift of your fingers I imagine that they may be easily lost in a fall on the ski slopes when you lose your glasses or take a face full of snow that dislodges one or both of the lenses but not the frames. But it is a novel idea and an excellent solution for people that do multiple activities and need different glasses for each activity but only want to buy one pair for everything.
