Field of view

The viewing angle provided by virtual reality glasses is the angular size of the space that falls into the user's field of view. Usually, the characteristics indicate the size of this space horizontally; however, if you need the most accurate information, this point needs to be specified separately.

The wider the viewing angle — the more the game space the user can see without turning his head, the more powerful the immersion effect and the less likely that the image will be subject to the "tunnel vision" effect. On the other hand, making the field of view too wide also does not make sense, given the characteristics of the human eye. In general, a large viewing angle is considered to be an angle of 100° or more. On the other hand, there are models where this indicator is 30° or even less — these are, usually, specific devices (for example, drone piloting glasses and augmented reality glasses), where such characteristics are quite justified given the overall functionality.

Lens distance adjusting

The ability to move the lenses of the glasses back and forth, thus changing their location relative to the screen and the user's eyes. The specific meaning of this function can be different: it can adjust the angle of view (so that the screen fits completely in the field of view and at the same time is not too small), play the role of diopter correction (which is important for users who wear glasses) or focus, change the setting interpupillary distance (see below), etc. These nuances should be clarified separately. However, anyway, this function will not be superfluous — it makes it easier to adjust the glasses to the personal characteristics of the user.

Pupillary distance adjustment

The ability to adjust the interpupillary distance of glasses — that is, the distance between the centers of two lenses. To do this, the lenses are mounted on movable mounts that allow them to be moved to the right / left. The meaning of this feature is that for normal viewing, the centers of the lenses must be opposite the user's pupils — and for different people, the distance between the pupils is also different. Accordingly, this setting will be useful anyway, but it is especially important for users of a large or petite physique, whose interpupillary distance is noticeably different from the average.

At the same time, there is a fairly significant number of glasses that do not have this function. They can be divided into three categories. The first is devices where the lack of adjustment for the interpupillary distance is compensated in one way or another (for example, by a special form of lenses that does not require adjustment). The second is models where this adjustment is not needed in principle (in particular, some augmented reality glasses). And the third — the simplest and cheapest solutions, where additional adjustments were abandoned to reduce the cost.

Magnetic button

The presence of a magnetic switch in the design of virtual reality glasses.

A similar switch is found only in models designed for telephones (see "Intended use"). It is usually installed on the side of the glasses and looks like a movable metal element. The meaning of this function is that when the switch is moved, the magnetic field inside the glasses changes, and most modern smartphones are equipped with sensors that can track these changes. Thus, the user gets extended control options: for example, in shooting games, the magnetic switch can play the role of a trigger.

Material

The main material used in the construction of the hull.

Plastic. Having a relatively low cost, plastic is at the same time quite practical, lightweight, easy to process and generally well suited for virtual reality glasses. This material is most popular in modern glasses, it is found in models of all price categories — from low-cost to top. Note that the actual quality of the plastic may be different, it also depends markedly on the price.

Cardboard. Glasses made of classic cardboard — thick thick paper. The main advantage of this material is its extremely low cost — even lower than that of plastic. The case, usually, is delivered unassembled, it must be folded in a special way before use; however, for some users, this is also an advantage, because. working with the "constructor" provides additional interest. In addition, cardboard is considered a more “environmentally friendly” and easy-to-recycle material. On the other hand, the strength and rigidity of such cases is very low, they are easily deformed and require careful handling. And the comfort during use is very conditional: soft pads are usually not provided at the points of contact with the face, the edge of the cardboard sheet is directly adjacent to the skin. As a result, this material has become widespread only in glasses for mobile phones (see "Signal source"), created as extremely simple and affordable solutions.
...
Cloth. Glasses with a case made of dense thick fabric. Such cases are relatively inexpensive, although much more expensive than the same cardboard cases (see above). On the other hand, fabric glasses are much more reliable and at the same time more comfortable — in particular, they almost always have soft inserts at the points of contact with the head, and the fabric surface itself is pleasant to the touch. Most of these models are designed for mobile phones (see "Signal source"), while the design may include original details — for example, a "pocket" for a mobile phone, fastened with a zipper. Also note that the fabric itself looks interesting even in neutral colours, and design options can be very unusual — for example, denim, camouflage, bright embroidery, etc. Among the shortcomings, it is worth noting the sensitivity of the fabric to dirt — despite the fact that the ability to remove and wash the upper shell is far from mandatory for such gadgets.
