"We want as many people as possible to wear it," she said.
To that end, Glass's designers picked four basic but distinct frame styles. On one end is a chunky "bold" style that stands out. On the other is a "thin" design—to blend in as much as possible.
Olsson said Google won't be able to compete with the thousands of styles offered at typical eyeglasses stores. Instead, Glass's designers looked at what types of glasses are most popular, what people wear the most and, importantly, what they look good in.
The latter has been a constant challenge for the nascent wearable technology industry, especially for something like Google Glass, designed to be worn on your face. When Google unveiled Glass in a video nearly two years ago, it drew unfavorable comparisons to Bluetooth headsets, the trademarks of the fashion-ignorant technophile.

In designing Google Glass, Olsson and her team focused on three design principles with the goal of creating something that people want to wear. These were lightness, simplicity and scalability. That last one means having different options available for different people—just as there are different styles of headphones, from in-ear buds to huge aviator-style monstrosities.
Google Glass currently comes in five colors—"charcoal," a lighter shade of gray called "shale," white, tangerine and bright blue "sky." The frame attachments out Tuesday are all titanium. Users can mix and match.
"People need to be able to choose," Olsson said. "These products need to be lifestyle products."
