FORTUNE — Earlier this month, Fortune reported that trendy eyeglass maker Warby Parker had raised $60 million in new venture capital funding from existing investors. Now comes word that the round came at a valuation of approximately $500 million.

This is around double where Warby Parker was valued when it last raised money, a two-part $41.5 million Series B round that included closes in both September 2012 and January 2013.

Tiger Global Management led the new investment, and was joined by return backers like General Catalyst Partners, Spark Capital, Thrive Capital and First Round Capital. New York-based Warby Parker has raised a total of $116 million since being founded in 2010.

Warby Parker declined to comment on valuation for our original story, and a company spokesperson was unavailable to speak for this update.
