A companion solution to the weight and size issue is simply putting the screen closer to your eyes. This has two advantages. Second, thanks to Archimedes and his lever law, the closer to your face the display is, the less force it applies, regardless of weight.

This presents a problem. The result would be trying to see your virtual world through a very narrow view, like trying to navigate the real world with a pair of blinders on. The solution to some of this is to put a lens, or series of lenses, between your face and the display.

The goal is to bend the light and give you a wider field of view, using what are essentially magnifying glass lenses, than what you could get with your naked eyes. You could even move the screen to what would normally be uncomfortably close to your eyes, but with the right lens es , the view would be perfectly comfortable. But when you introduce lenses and try to turn a small field of view into a wider one, you introduce new problems vis-a-vis the aforementioned aberrations.

Camera lenses solve this with a complex stack of lenses that combine their distortions to attempt, at least, to cancel out all the aberrations and give you a clean, undistorted photo. Unfortunately, all of these lenses add weight, length, and quite a bit of cost, as any photographer can tell you.

Instead of a smooth shape, a Fresnel lens is relatively thin and has a series of concentric rings carved into it, which is designed to bend rays of light differently depending on what part of the lens they hit.

This, if designed correctly, can help overcome the aberrations encountered in using just a single lens or in the case of an HMD, a pair of lenses. Unfortunately, again, this does not solve all problems. For modern HMDs, the solution presently in use is a software trick; you have to pre-warp the image in the inverse of the distortion the lens produces, resulting in a near correct image once viewed.

And there you have it, a wide field of view with something like a correct image, all from a much smaller screen placed in front of your face, with the image running through a lens. What a great decision to order your product. I have already recommended your product line to other friends who play on Vr, really love what you all are making.

Thank you very, very much! What an amazing customer support! I will buy another pair for my fiancee for sure. Out of interest the VR lens solution has transformed my VR experience. They arrived today, and I am very impressed with the packaging as well as the quality of the product. The replacement lenses you sent to me arrived today and they fit perfectly.

Thank you for the great customer service. It is a pity that you do not have a location here in the US so that shipping times would be somewhat shorter. I look forward to doing business with you in the future. Thanks again. Thank you for this awesome product.

I just wanted to say that I am thoroughly satisfied with my lenses. I am sorry if I was difficult during earlier exchanges, I was just super confused. Thank you for making such an amazing product that ultimately is also a safeguard! I used to use my Index with glasses. It became uncomfy after a while. Too much pressure on my nose. Ordered lenses from vrlenslab. Your company has really great customer service, and I do appreciate The way you have been keeping in touch with me.

I love the guards — they are very high-quality. I know this because my father is an optician and I have grown up around this all my life. I think we may do a review from an opticians perspective of the eyeglasses when they come to us.

There is very little information available to consumers and the public regarding eyewear and lenses in virtual reality headsets.

I think this will be a growing market in the future — I hope it brings you much success and helps millions of people enjoy virtual reality more. I purchased one of your products back in for my HTC Vive. I wanted to extend my gratitude once again. Here we are 4 years later and the lenses are undamaged and work just as well as the day I bought them despite thousands of hours of use. The markets are saturated with products of inferior production and quality and yet your lenses and their frames are top notch and highly affordable.

I hope you have many successful years ahead! Learn more.
