From 2024 and beyond, virtual reality is poised to mature both in hardware and use cases, particularly within the metaverse and industrial metaverse. This often-overlooked Pancake optics design will be the catalyst for these advancements, enhancing mixed reality experiences for employees and enabling the development of industrial metaverse solutions through platforms like Microsoft Hololens and the wider metaverse world.

Blue light filtering lenses are designed to block a portion of harmful blue light emitted from digital screens, smartphones, and other electronic devices.

When comparing Fresnel lenses to Pancake lenses, several factors come into play: the light source, lens shape, and how the light travels through and exits the lens, as well as the wavelength of the light. Fresnel lenses offer a wider field of view but suffer from chromatic aberrations (ghosting and overlapping colours) and pincushion distortion, which requires real-time software calibration that consumes processing power.

Professionals working night shifts or irregular hours can maintain their circadian rhythm by wearing blue light-filtering lenses, promoting better sleep quality during the day.

Pancake optics, however, fold multiple lenses together, bouncing light within the glass or plastic. This allows for a slimmer design, reducing the space between the display and the user's eyes and eliminating distortion issues present with Fresnel lenses. Pancake lenses also do not exhibit chromatic aberration, freeing up processing power for other tasks.

Workers in environments where precise vision is critical, such as laboratories or construction sites, benefit from AR coatings that enhance focus and accuracy.

Though Pancake optics may seem like a new concept, they’ve been used by the military and scientific community long before VR adopted them. The first Pancake VR headset prototype emerged in 2015 from eMargin, followed by Kopin’s "Kopin Elf" in 2017. More recently, companies like Huawei, HTC, Pico, and EM3 have either launched commercial Pancake-enabled headsets or showcased concept designs.

These Pancake-enabled VR headsets are redefining the perception of VR, shifting from bulky devices to sleek, fashionable wearables. This shift not only makes VR more accessible to the early majority of consumers but also expands the market, driving innovation across the industry. As the industrial metaverse grows, especially with platforms like Microsoft Mesh and devices like Microsoft Hololens, thinner, more powerful headsets will enhance mixed reality experiences for both enterprises and frontline workers worldwide.

By integrating with Windows and other digital tools, HoloLens plays a crucial role in driving digital transformations across industries, reshaping how businesses engage with the metaverse and mixed-reality solutions.

Prolonged exposure to blue light can disrupt sleep patterns and contribute to digital eye strain. Blue light filtering lenses mitigate these effects, promoting better sleep and reducing eye fatigue.

However, Pancake lenses have lower light efficiency due to internal light bouncing, which can dim the perceived image. This is why high-brightness micro displays, like those mentioned by Fan, are essential for optimal performance. Additionally, Pancake lenses still struggle with ghosting.

In virtual reality HMDs, this design creates a "lighthouse-beamed screen" effect, requiring a significant gap between the display and lens, thus adding bulk and weight to the headset. As industries embrace the metaverse, mixed reality, and spatial computing—seen in platforms like Microsoft Mesh and devices like Microsoft Hololens—streamlining this bulky design is crucial for the future of immersive experiences in the industrial metaverse and beyond.

The Metaverse refers to user-generated online spaces where individuals engage with computer-created environments and digital characters. Virtual reality (VR) fully immerses users in these simulated environments, while augmented reality (AR) integrates digital elements into the physical world.

Overall, Pancake lenses offer more advantages over Fresnel lenses, especially in terms of image quality and enabling thinner, lighter VR headsets. This innovation is critical as the VR market expands into the industrial metaverse, mixed reality, and collaborative platforms like Microsoft Mesh and Microsoft Teams. These advancements are poised to transform VR/AR solutions for the enterprise, frontline workers, and the broader metaverse world.

Augmented reality (AR) is pushing toward affordability and slim designs, largely driven by advancements in waveguide technology. Meanwhile, future virtual reality (VR) headsets will likely evolve around Pancake lens technology.

In mid-June 2021, Kopin unveiled the P95, an all-plastic Pancake lens design optimised for their 2.6K x 2.6K OLED high-brightness micro displays. Dr. John C.C. Fan, CEO and founder of Kopin Corporation, highlighted that this new technology is "ideal for VR" and marks "a foundational milestone for the emerging VR markets." According to Fan, bulky, heavy headsets have long hindered consumer adoption, and this breakthrough aims to change that.

When consumers and enterprises not deeply engaged in VR/AR news think of virtual reality headsets, they often picture bulky "shoeboxes" strapped to the head. This perception persists despite design efforts to reduce the bulk since VR’s resurgence in 2012. Even technology enthusiasts and industry experts tend to focus on display specs—pixel density, refresh rates, colour accuracy—while overlooking another key component: the lenses.

By minimizing reflections, AR coatings enhance visual clarity, improve night vision, and reduce eye strain, making them an excellent choice for individuals who spend long hours in front of digital screens or under bright lights.
