Comparison Rokid Max 2 vs XREAL One Pro M

A universal connector in smart glasses for charging, connecting to a smartphone, laptop, or other compatible devices. In simple smart glasses, it is more often used only for power and data transfer, such as charging the battery or copying taken photos and videos.

In AR glasses, USB-C might be more important: through it, images from a phone, laptop, or gaming console may sometimes be transmitted if video output is supported. Therefore, when choosing, you should look not only at the presence of USB-C but also at its capabilities: charging, data transfer, or image output.

The number of pixels that form the image in AR glasses. It is most often specified separately for each eye. The higher the resolution, the clearer the text, interface, video, and virtual screen appear; for example, 1920×1080 per eye is already suitable for movies, games, and basic window work.

When choosing, it is important not to confuse resolution with the size of the virtual screen: the glasses may claim a large screen of 100–120", but clarity still depends on the number of pixels, optics, and the quality of the microdisplays themselves. Higher resolution is especially useful for reading text and working with PCs, while requirements for simple video viewing may be lower.

The field of view characterizes the width of the visible digital image in AR glasses, i.e., how much space in front of the eyes the virtual screen or interface occupies. The larger the value in degrees, the wider the image is perceived: for example, 30 – 35° is suitable for basic video viewing, 40 – 50° is more comfortable for gaming and working with windows, and 50°+ provides a more pronounced big screen effect.

In AR glasses, this parameter should not be confused with the viewing angles of a regular monitor or TV. Here, it's not about how the picture is seen from the side, but about how widely the image unfolds in front of the user's eyes.

The ability to adjust the glasses’ optics to the user’s vision characteristics, most often to compensate for nearsightedness or farsightedness within the supported range. Diopter adjustment<|a> is needed so that the virtual screen, text, menus, and small interface elements appear sharper without requiring separate corrective lenses.

This feature is especially useful for AR glasses, where the user looks at a virtual screen in front of their eyes for a long time: a blurry image quickly causes eye strain and makes text difficult to read. However, diopter adjustment does not always replace regular glasses or custom lenses, because the adjustment range is limited, and astigmatism or complex correction may require a special optical insert.

The distance between the centers of the user's pupils for which the glasses optics must be calculated. The value range indicates the interpupillary distance for which the glasses can correctly align the image with the pupil position.
