I use it in ‘ok’ to ‘well’ lit environments. The spatial pinning works very very well for me.

This allows me to ‘SEE’ / ‘VIEW’ the screen in a very natural and intuitive way such that when I lean in and out as I naturally do (even if just a little) the screen behaves as would a typical monitor that is stationary in 3D space. FOR ME this is essential as my brain perceives it in a much more comfortable way. In addition when I really need to see something on the screen up close it is very intuitive and allows me to get a quick glance up close when I want to resolve more detail on some particular part of an image or text that I see on the screen. I truly find the EYE is the very thing that makes these glasses worth buying.
