That said, it is rather difficult to convey the experience of seeing with Dynamic Eye glare shield sunglasses online. Pictures of scenes with the sun glaring in the background can be taken with or without the sunglasses, but they suffer from the limitations of both the camera and the computer screen. Neither device has anywhere close to the dynamic range of response that the human eye has. In other words, a camera cannot record, nor can the computer screen portray, the brightness of the sun, or even oncoming headlights.

The pictures above are unmodified photographs of a glare scene through a functioning prototype with glare-shielding turned off (top) and (bottom). Like your eye, the camera reduces its sensitivity with the full force of the sun, so it can’t see as much as when the sun is shielded. The shielded region is the fuzzy purple surrounding the sun in the right hand photograph. The edges are fuzzy because the camera is focused beyond the shielding spot, just as your eyes are when wearing them.
You can also see that in spite of blocking a region around the sun, the darkened region is a small portion of the total field of view. The human eye has an even wider field of view than this camera, so the relative size of the dimmed portion is even smaller.
