California ophthalmic incubator ForSight Labs is seeking $6 million in order to fund its VISION6 project, the latest in a string of developments spun out of the company.

The company declined to provide details on the new initiative, but an SEC filing shows that ForSight has already raised $1 million through sales of equity. The funding round began April 25 and there is 1 unnamed investor listed thus far.

The new round comes just a few weeks after ForSight raised $15 million in a Series C round for its VISION5 project, the Helios ocular implant. That financing round was led by H.I.G. BioVentures of Miami, according to a press release. Prior backers Morgenthaler Ventures, Versant Ventures, Technology Partners, and Delphi Ventures also participated.
