Field of View in VR and XR Glasses: Why FOV is becoming important again

Field of View, or FOV, was long one of those VR specifications that were discussed primarily by enthusiasts. In 2026, FOV will again become a central topic – precisely because XR glasses are becoming smaller, lighter, and more like glasses.

The trend towards the glasses format brings enormous advantages in terms of weight, comfort and everyday usability. At the same time, the digital image area on many of these devices is shrinking. Classic VR headsets in the „ski goggles“ format, on the other hand, usually offer a significantly larger field of view and thus more peripheral image information. The current debate is therefore no longer just about: Which glasses have the highest resolution? Rather: How much field of view do we actually need for true immersion – and how much of that are we willing to give up for a lighter device?

The connection with Immersion and Presence is immediate: If the virtual world covers only a small portion of the natural field of vision, the user can perceive the limits of the display more clearly. With a large FOV, the virtual image extends further into peripheral perception and can more fully „envelop“ the environment.

What does the field of view mean for VR and XR glasses?

The Field of View describes the viewing angle that a user can see through a headset or XR glasses. In XR devices, three different specifications are usually used:

• horizontal FOV – how far the image extends to the left and right,
• vertical FOV – how far it extends upwards and downwards,
• diagonal FOV – the diagonal angle of the visible image area.

At first glance this seems trivial, but in product comparisons it quickly leads to misunderstandings. Manufacturers do not always mention the same measurement unit. One device may be advertised with a horizontal FOV of 110°, another with a diagonal FOV of 116° and a third simply with „70° FOV“. These values cannot be directly compared with grades in school.

In addition, the actually perceived field of view also depends on facial shape, eye distance, eye relief, lens position, face cushion, and IPD setting. Therefore, two users can subjectively experience the same headset with slightly different FOV.

Why does FOV affect immersion?

Our visual system not only perceives the sharp center of the field of view. Peripheral perception also provides important information about movement, orientation, and spatial structure. A headset with a small FOV can therefore quickly give the impression of looking through a diving mask, binoculars, or a window into the virtual world.

A larger FOV reduces this „tunnel vision“. The virtual environment extends further outward, and the user no longer has to consciously turn their head to perceive things that would already be in the peripheral area when seeing naturally.

That doesn't mean that a large FOV alone produces good VR. Tracking, resolution, frame rate, contrast, lens quality, and interaction remain just as important. But if a headset is set to maximum Immersion As designed, the field of view is one of the key parameters.

2026: The FOV will become smaller because the glasses will become smaller

What is exciting is that the development is currently moving in two directions. On the one hand, there are classic VR/MR headsets with large lenses and relatively wide fields of view. On the other hand, extremely lightweight devices are emerging that approach the size of a normal pair of glasses.

It is here that the technical compromise becomes particularly evident. Large displays and optics require space. A large field of view also requires the optics to be able to cleanly display a wide angle without producing distortions, blur, or excessive size.

At XR glasses in eyeglass format Therefore, a part of the FOV is often sacrificed to reduce weight, thickness, and thermal load. This is not a developmental flaw, but a conscious prioritization.

Current examples: from 70° to over 110°

Important: These values are not completely comparable because manufacturers use different measurement directions and measurement methods. The table therefore primarily shows the magnitude of the current design tradeoffs.

Meta itself now makes the difference very clear: the new Meta VR Glasses are specified with a 70° FOV, whereas the Quest 3 reaches 110° horizontally. With XREAL AURA, 70° is already a significant improvement over previous Optical-See-Through glasses – in this device class, implementing such a field of view is technically much more difficult to achieve.

70° FOV: bad or simply not suitable for another use?

It is precisely this question that is currently sparking the discussion among VR enthusiasts. Those who come from PC VR, racing, flight simulation, or classic VR games often find a significantly smaller FOV to be a step backward. The goal here is to perceive as little as possible from the headset and to see as much of the virtual world as possible.

For other applications, a smaller FOV can be perfectly sufficient. For those who primarily use virtual monitors, browser windows, movies, or productivity apps, there is no need to have a permanently wide 110° digital image. A virtual screen also only occupies a portion of our field of view in reality.

Therefore, the FOV debate is ultimately also a discussion about the future of XR: Should a pair of glasses replace the real world as completely as possible – or should it comfortably integrate digital content into our normal field of vision?

Optical see-through changes the perception of the FOV

With optical-see-through devices like XREAL AURA, the FOV must be interpreted differently than with a closed VR headset. The real world remains directly visible outside the digital image area. The user therefore does not see „black“ outside the 70° window – he still sees his surroundings.

This can even be beneficial for AR and spatial computing. Digital content appears in a limited area, while peripheral real-world vision remains intact.

However, this advantage does not work for fully immersive VR. As soon as the goal is to blur the real world and completely immerse the user in a virtual environment, a limited digital image area becomes noticeably more noticeable.

Video pass-through and FOV

With modern MR headsets like Quest 3 or PICO 4 Ultra The user does not see the real world directly, but through cameras and displays. This allows the entire display FOV to be used for both VR and mixed reality.

That is one of the reasons why today's pass-through headsets are very flexible devices: they can represent a completely virtual world and seconds later combine the real environment with digital objects.

The price for this is the larger headset format. Cameras, displays, lenses, batteries, and computing hardware all require space – even though the devices have become considerably more compact since then.

FOV vs. PPD: more field of view costs pixels

A wider field of view also has a second advantage: the existing display pixels must be distributed over a wider angle.

Here it comes PPD – Pixels per Degree In gaming. A narrow FOV can allow for a higher pixel density per degree with the same display resolution. The image then appears sharper, even though the total resolution does not need to be any higher.

To achieve very large FOV and high PPD simultaneously, a headset requires correspondingly high-resolution displays and significantly more rendering power. Technologies such as Foveated Rendering They are therefore becoming increasingly important: they are trying to shift computing power specifically to where the eye is actually looking.

Why „larger FOV“ does not automatically mean „better glasses“

Several parameters are relevant for image quality. Our article on the conflicts of interest provides a broader overview of these issues. Technical challenges with VR glasses:

• FOV: How much of the virtual world is visible at the same time?
• PPD: How many pixels are available per degree of field of view?
• Edge-to-Edge Clarity: Does the image remain sharp even outside the optical center?
• Binocular overlap: How large is the area that both eyes see together?
• Contrast and Black value: Particularly relevant for OLED and micro-OLED systems.
• Misinterpretation: How cleanly does the optics correct geometric distortions?
• Weight and Eye Relief: How close can the eyes actually be to the lenses?

A theoretically wide FOV is of little use if the outer areas of the image are blurry or the headset can only be used with an annoyingly small viewing distance.

Which FOV is needed for which application?

VR Gaming and Simulation

Here, a wide FOV is particularly valuable. In racing or flight simulations, peripheral vision improves orientation. Even in fast VR games, a wider field of view greatly contributes to the feeling of actually being in the virtual environment.

VR Training

For VR Trainings The importance of the FOV depends on the scenario. In spatial work processes, machines, or dangerous situations, peripheral vision can be important. In focused soft skill training, however, stable, credible interaction is often more important than a maximally wide field of view.

Virtual monitors and productivity

Here, a smaller FOV can work well. What matters more are text clarity, PPD, comfort, and weight. That’s why lightweight XR glasses can be more attractive for long office sessions, despite having a smaller FOV, than heavy headsets.

AR and Spatial Computing

In optical-see-through glasses, the real environment remains visible anyway. A larger digital FOV is desirable, but not every application requires a completely enclosed virtual environment. For navigation, contextual information, or virtual displays, a smaller FOV may be sufficient.

Trade shows and events

In an event, handling is just as important as immersion. An extremely wide FOV is of little use if the glasses are heavy, difficult to adjust, or uncomfortable for short sessions. For VR events and trade show applications Therefore, a balance must always be struck between immersion, comfort, robustness, and throughput.

The current XR trend: comfort versus immersion

In 2026 it will become clear that the XR market is becoming more differentiated. There is no longer just one ideal pair of glasses.

The new lightweight devices try to, XR in the glasses format Make them suitable for everyday use. Less weight, smaller optics and external compute chips allow for glasses that look significantly less like traditional VR headsets. The price is often a smaller FOV.

At the same time, for VR enthusiasts, simulators, and applications with maximum presence, the wide field of view remains a very important quality feature. Devices like the Bigscreen Beyond 2 show that even compact headsets are trying to combine both: low weight and a still VR-typical wide FOV.

The most exciting development of the coming years therefore should not simply be „ever larger FOV“, but the question of, How much FOV can be accommodated in how little volume.

Conclusion: FOV is once again one of the most important XR specifications

Field of View has never been unimportant. However, the current trend towards the glasses format makes it clearer what impact the field of view has on the type of XR experience.

A 70° device can work excellently for virtual displays, spatial computing, and many AR applications. For complete VR immersion, however, the same value may feel like a clear step back compared to a headset with around 105 to 110°.

Therefore, in FOV there is no universal „more is always better“. The goal of the application is crucial. For maximum immersion, we want to see as much of the virtual world as possible. For everyday usability, productivity, or lightweight AR glasses, weight, PPD, and comfort may be more important.
