The virtual reality helmets are a reality in many homes and jobs. Are an impediment deformations and eye diseases present in the population?
The incipient massive arrival of virtual reality has many curious wondering about how different defects and pathologies of our eyes are affected with virtual reality helmets.
the good news is that almost everything has traditional solution, we can use the helmets most virtual reality without removing his glasses. it’s not the perfect choice but will serve for most if you have an incredibly large glasses.
the second prior solution is the use of lenses of our eyes. For many it is a way they do not want to take, but for others it is more comfortable. As you can tell, there is absolutely no additional problem when using lenses with virtual reality helmets beyond the typical problems of the lenses. Can you move around the real world without glasses? Then you will not have any problem with virtual reality helmet. Do you need glasses? There is also no problem.
Myopia and hyperopia
These defects eye are the most common. The light beams intersect within our eye before reaching the retina in the case of myopia, or come to our retina without being crossed in the case of farsightedness. This makes us see fuzzier as distant objects to increase this deformation.
Oculus Rift, HTC Vive, Samsung Gear VR and PlayStation VR all have a way to zoom in or out the screen. Typically, not having the same diopters in both eyes, so the perfect solution in the virtual reality helmets would pass through the two lenses to adjust individually to zoom in or out independently. If you have less than 7 or 8 diopters can use any of these models without your glasses adjusting the maximum position of the screens, but also depends on having very similar diopters.
astigmatism
Unfortunately astigmatism is difficult to solve in these cases, and although some people will in the future-or in kits development- own adapted lenses are believed to each of his eyes, most users with these problems must resign themselves to wear helmets on glasses or use contact lenses.
Distance between our pupils
Not all people have a standard separation between our eyes. Typically are 63 or 64 mm distance in one eye to the other, but some have more and others less. You can usually make some correction software when it comes to a slight distance of a few millimeters more or less. This can cause one eye, or both, focus bad part or all of what is presented. Oculus solved this in the Rift version of consumers who are coming to market these days.
for versions of early development of Oculus Rift have added a few simple 3D printed allow raising of the lens and get eliminate that distortion.
HTC Vive also includes this feature, and adjusts the distance with a small screw on the side.
Unfortunately for PlayStation users who do not have a “standard head” PlayStation Vr will not have this option on a physical level. When you have only one large horizontal screen instead of two vertical by like eye Rift and incubators, the PlayStation VR software solves emulating him with some extra distance. Still, Sony claims that any distance between 55 and 71 mm will be comfortable with his helmet. However, many users who have tried the three options discussed PlayStation VR is the most comfortable for long periods of time.
