Warby Parker, a New York City-based eyeglasses retailer, raised $75m in Series E funding.
The round, which reportedly values the company at $1.75 billion, was led by existing investor T. Rowe Price.
The company will use the funds to continue to expand the business.
Co-founded in 2010 by Dave Gilboa and Neil Blumenthal, Warby Parker sells eyeglasses, including prescription lenses, sunglasses, online and in stores, at relatively affordable prices. The company also offers a collection of related products.
