   fresnel lens for pc gaming
Building a collimated display for pc games and flight simulators using a common fresnel lensI was wondering if anyone here has tried this, and how effective it is. It's supposed to give the image on the screen more depth and make the experience more immersive, and it's less straining on the eyes because it makes them focus father away. My brother plans to buy one from this site, if it works well I might get one too.
