(A spokesman says that’s not significantly more than a standard pair of bifocals or progressive lenses in a designer frame, which can easily top $1,000. Plus, he says, wearers are avoiding eye strain that could worsen their vision.) The glasses need a battery that lasts 4-5 days, but they come with a charger.
