Pixel Density & Retinal Resolution, and Why It’s Important for AR/VR


Road to VR has released a new article that really takes a dive into how VR plays a trick on our eyes and the science in Pixel density and resolution in VR.

They get pretty technical in terms of what is happening every second you experience VR they go on to say "If you have a VR headset, you can calculate the pixel density—how many pixels per degree it presents to the eye—by dividing the number of pixels in a horizontal display line by the horizontal field of view provided by the lens.

For instance, the Oculus Rift DK1 dev kit (yes, I know that was quite a while ago) used a single 1280 x 800 display (so 640 x 800 pixels per eye) and with a monocular horizontal field of view of about 90 degrees, it had a pixel density of just over 7 pixels/degree (640 ÷ 90).
