Google Glass users can update with new prescription frames and sunglasses shades, Google announced Monday.

The company plans to roll out Google Glass for the general public later this year, the Los Angeles Times reported.

Early users already have the second version of Google Glass, which was released in late 2013, and now can purchase four new types of prescription frames and two types of sunglasses shades.

Google offers bold, curve, thin and split choices for frames; altogether, users now have 40 different style combinations to choose from, the company said.

Frames cost $225 each, while each pair of shades costs $150.

"This marks the next phase in the evolution of Glass as we move toward a wider consumer launch later in 2014," Google said in a statement provided to the L.A. Times.

Google worked with frames and lens maker VSP Global to make the new frames. Users can take their devices, frames and prescriptions to Google preferred eye care professionals, which are currently only found in New York, San Francisco and Los Angeles. A professional must cut and fit the prescription lenses.

The Wall Street Journal earlier reported that Google was in talks with VSP to put prescription lenses in the Glass device.

Putting a small computer screen in front of the wearer's eyes, Google glasses hold a miniature computer that responds mostly to voice commands.

"Down the road I think this technology is going to blow up," said Matt Alpert, an optometrist in Woodland Hills, Ca., a member of the VSP Global board and an early tester of Google Glass. "As soon as apps are developed that are relevant for your world, it will start to take off."
