Great thing! I can already see the infomercials for this:
"I wear prescription glasses. Now I can watch 3D movies without piling on glasses and looking like a freak!"
"Now I can watch 3D while diving!"
"My kids just love it, and I love it too! No handles to break off, no glass to scratch... We used to go through at least four pairs of glasses a year in my family; Winkeroo is going to last a lifetime!"
