On November 9, source @elnarvideo posted a series of tweets on the X platform, reporting that Samsung’s first mixed reality headset, the Galaxy XR, suffers from optical design issues that cause noticeable eye strain and discomfort during use.
The user noted that when viewing distant objects in the virtual environment through the Galaxy XR, their eyes experienced significant fatigue and discomfort. In contrast, looking at nearby objects felt considerably more comfortable. The user speculated that the root cause lies in design trade-offs Samsung made in pursuit of a wider field of view (FOV).
It is believed that Samsung may have positioned the internal display closer to the lenses. While this approach enhances immersion, it has the side effect of shortening the focal plane—the distance at which the human eye naturally focuses most comfortably—from the industry norm of around 1.2 to 1.8 meters (4 to 6 feet) down to approximately 0.9 meters (3 feet). IT Home has included relevant screenshots as reference.
When the eyes are forced to focus on a physically near focal plane while simultaneously perceiving virtual objects that appear to be far away, a phenomenon known as vergence-accommodation conflict​ occurs. This is a well-documented cause of eye strain in VR devices.
To mitigate the discomfort caused by this issue, the user also observed that Samsung’s Android XR operating system, which powers the Galaxy XR, artificially limits the maximum placement distance of virtual windows to roughly 2.4 to 3 meters (8 to 10 feet). This software-based restriction serves as a compensatory measure to optimize the user experience.
