The futuristic shades use a specially designed holographic film to miniaturize the lens. Conventional VR displays tend to be bulky, as the refractive lenses inside of them need a couple inches to focus the display for its wearer's eyes. The result is a pair of glasses that are at most [only nine millimeters thick](), according to the researchers, and weigh only 17.8 grams. Images from the glasses' green-and-black display are, frankly, extremely cyberpunk. The glasses can provide an approximately 90-degree horizontal field of view (human vision is just shy of 180 degrees), according to testing detailed in a [new paper]() published by Facebook Research. ## Laser Beams The design also did away with the traditional LCD panels used in conventional VR headsets and uses lasers instead to create an image. That means pixel counting isn't really an option, as *Ars* points out. It's still an early prototype with plenty of limitations. Since light rays from the backlight "fan out significantly before they are focused by the holographic beamsplitter surface," large regions of the display "do not contribute to the display’s \[field of view\]," the researchers write in the paper. The glasses are also still not capable of producing a full color image and exhibit "ghosting" around the edges of the field of view caused by optical surfaces reflecting light. The team already has a plan to reduce weight even further. By switching to plastic substrates, the researchers expect to bring total weight to just 6.6 grams, about the weight of a pair of large aviator-style sunglasses. **READ MORE:** [How holographic tech is shrinking VR displays to the size of sunglasses]() \[*Ars Technica*\] **More on VR:** *[A Tokyo Hospital Is Livestreaming Surgeries in Virtual Reality]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
