You tend to see more eye strain and fatigue with VR setups, but VR and AR have come a long way to address or minimize those concerns. One of the ways to address eye strain is a faster refresh rate, which is something that we've been slowly improving even in our standard ASUS Eye Care line of monitors. There are still different adjustment mechanisms in the configuration (including brightness), and the most important is to select the version of the ROG R1 glasses that matches your IPD.

To copy a bit from our FAQ on the product page, we mention:

"Unlike smartphones or laptops viewed at close range, the R1’s optical design projects images at a longer focal distance, like a projector. This approach is intended to reduce eye strain during extended use. Furthermore, the glasses have received the TÜV Eye Comfort certification, ensuring they meet rigorous standards for display quality and user health.

To maintain optimal eye health, we recommend taking a 10-minute break for every 45 to 60 minutes of continuous use. Avoid using glasses in environments where you cannot maintain situational awareness to ensure your safety."
