One of the quieter but more stubborn problems in XR hardware isn't resolution or field of view, it's something more basic: the discomfort that comes from your eyes constantly trying to refocus between virtual images and the real world. AllFocal Optics, a deeptech startup building nanophotonic lens technology designed to keep images perpetually in focus, has just raised $5.3 million to push that solution toward the market, combining a $3.6 million equity round led by SpeedInvest with additional support from Innovate UK grants.

The company's pitch centers on ultra-thin lenses capable of recreating something close to natural human vision, aimed at making viewing more comfortable across smart glasses, head-up displays, immersive gaming, and beyond. That's not purely theoretical at this point either: an automotive HUD application of the technology is already lined up for a trial early next year in partnership with Jaguar Land Rover, and AllFocal Optics says it expects its lenses to show up in AR glasses and VR headsets within the next two years.

The core idea behind the technology is projecting a digital image directly onto the user's retina so it stays in focus no matter how the eyes adjust to whatever is happening around them, which the company argues eliminates the nausea and visual discomfort that often accompany extended VR, AR, or mixed reality use. AllFocal Optics founder and CEO Dr. Pawan Shrestha described that discomfort as one of the central obstacles standing between XR and true mass adoption, noting that the lenses work with LCD, OLED, or essentially any display type, including for users who would normally need glasses to see clearly. The technology traces back more than a decade of research led by Shrestha, a Cambridge University spinout founder and former Royal Academy of Engineering enterprise fellow, and the company has also brought on Dr. Ash Saulsbury, a former Microsoft VP of Technology and AI and AR leader at Meta, as its new Chair.

Beyond SpeedInvest, the funding round drew support from a notably varied group of backers, including 7 Percent Ventures, an early Oculus VR investor, along with Martlet, Another.VC, former professional footballer and business angel Mario Götze, former Silexica CEO Maximilian Odendahl, and serial entrepreneur Prashant Shah. SpeedInvest's deeptech partner, Rick Hao, described AllFocal's patented approach to nanophotonics as a meaningful enabler across smart glasses, head-up displays, and defense applications alike, framing the investment as a bet on the company's ability to push visual technology forward across all of those markets at once.
