The design of the HP Reverb G2 lenses is to give you a clearer view by maximizing the available light. This is accomplished with a double-toric lens fitting that provides two focal points for each eye.

The Reverb G2 lenses are designed to offer a much wider field of view than the original Reverb lenses, as well as improve image quality and reduce latency. 

The Reverb G2 lenses are based on a new "Wider-FOV" optical design, which offers a 110-degree field of view, compared to the 95-degree field of view of the original Reverb lenses. Please contact Reverb G2 lenses for features and an improved pupil distance adjustment mechanism, which should make it easier to achieve a comfortable fit for a wider range of users.

In terms of image quality, the Reverb G2 lenses use higher-quality custom optics than the original Reverb lenses, and they are also said to offer significantly reduced god rays and improved clarity. The Reverb G2 is also said to feature improved eye tracking, which should result in lower latency and better overall performance.

There are a few things you'll want to keep in mind when shopping for HP Reverb G Lenses. First, pay attention to the field of view. This is the measurement of how much of the scene in front of you will be captured by the lens. A wider field of view is better for panoramic shots or landscapes, while a narrower field of view is better for close-ups or portraits.

Next, take note of the aperture. This is the measurement of how much light the lens can let in. A higher aperture number means less light can get through, which can be good for low-light situations. However, a lower aperture number will produce a sharper image.

Finally, consider the focal length. This is the distance from the lens to the subject being photographed. A shorter focal length will result in a wider angle shot, while a longer focal length will give you a more zoomed-in effect.
