Refinement of virtual reality glasses for farsighted
Currently, there are already a lot of different virtual reality glasses, which together with smartphones allow you to view stereo content. The market, especially the Chinese, presents various models of such glasses. Some of them have the adjustment of interpupillary distance and only a very small part also allows you to adjust the focal length for people with myopia. However, if you have hyperopia or astigmatism, then for comfortable use you may need more focal length. This article will discuss how to customize the glasses on the example of Baofeng Mojing 3 Plus and increase the focal length.

So, in the first thing we sort the glasses. To do this, you need to force out the metal rod that holds the lid, and remove it.
To disassemble the helmet with a knife or other sharp object, you need to separate the top coating from the plastic in the specified places, lift the edges and unscrew the self-tapping screws:
Remove the platform and substitute the previously printed inserts under the springs:
The inserts themselves look like this:
Further, optionally, you can cut a rectangular "window" in the removed part of the body. This will potentially increase the usable screen area (standardly it is limited to circles). For watching movies and games in SBS mode, this will be very useful:
The cut-out can be made manually with a metal cutting blade, but care must be taken not to damage the plastic around.
In order to start cutting, you may need the help of a regular soldering iron to melt small holes in the corners. In this case, the proverb "measure seven times, cut once" is very relevant, if you are, of course, not indifferent to appearance. In addition, you need to take into account the size of the screen used and cut the opening 2-3 mm smaller, so that the screen simply does not fall. In the case of 6 'screen should get something like this:
In conclusion, we install the upper part back and ( attention! ) Fasten it not with those short self-tapping screws, which we twisted, but we find the long ones about 15-20 mm:
It turns out that the upper part of the body points is removed from the base. Yes, now the standard focal length regulator is useless, because its transmission does not reach the cover. If you need to adjust the focal length, then do it, twisting or twisting screws on the perimeter.
Finally, in order to prevent dust and quarrels from settling on the screen, the resulting empty space (gap) between the base and the upper part of the body must be closed, for example, by wrapping a wide electrical tape or other suitable material:
As a result, we get an increase in the focal length of up to 10-15 mm, which makes it more comfortable to use glasses (a helmet) for people with positive or other visual features (individually).
Enjoy your VR!
