If you’re reading these words through bifocals or progressive lenses, your life could change in June.

That’s when a company called PixelOptics in Roanoke, Va., plans to release emPower, a line of electronic eyeglasses that let wearers toggle between two prescriptions, with settings for close-up and distance vision.

The new emPower glasses are expected to retail for between $1,000 and $1,250 per pair. The will be available starting in June.

After powering up for six to eight hours in a charging cradle, the glasses can run for more than three days. Their lenses, manufactured in Japan by Panasonic, feature a thin layer of liquid crystal sandwiched between two layers of plastic. When an electrical charge hits the liquid crystal, the molecules realign, altering the prescription.
