Last month Google product director Steve Lee said the company was working on a Google Glass reference model for prescription lenses for people that must wear glasses to correct vision problems. Following up on Lee's statement, Google has officially confirmed that a model for prescription glasses will be available by the end of the year.

The search giant made the announcement earlier today on Google+ where they said the question of whether or not Glass will work with a prescription is one of the most commonly asked. The team has been hard at work on it and because Glass is designed to be modular, you will be able to add frames and lenses that match your prescription.

The Project Glass team included a picture of Greg Priest-Dorman, a team member and early pioneer in wearable computing, wearing a prototype device they are testing to further illustrate the point. Google says the prescription kit won't be ready in time for the Explorer Edition's release but we can expect to see them later this year.

The Explorer Edition is being distributed to developers that pre-ordered the device as well as a select few that won the opportunity to buy the $1,500 augmented reality visor as part of a recent contest. The visor was first made available to Google I/O attendees to pre-order nearly nine months ago. The retail price for the headset is expected to be less than $1,500 when they become available to the public, we're told.
