Yes, I find that there are differences in eye strain between the regular and nanotexture displays, even in a dark room with no reflections. It's worth trying both. One interesting difference between the two that not a lot of people realize is that the light emitted by the regular screen is circularly polarized, while the nanotexture is largely non-polarized.
- zachh 2y agoCan you explain more about what that means / share a link to further reading? Tried searching but couldn't find much online about the light polarization specifically, and am interested in the nanotexture for reducing eye strain.
- AlanYx 2y agoThere's some evidence that CPL emissive screens cause less eyestrain than linearly polarized emissive screens (e.g., https://pmc.ncbi.nlm.nih.gov/articles/PMC9010255 https://pmc.ncbi.nlm.nih.gov/articles/PMC9010255), although the evidence there is not wildly strong. If you have a pair of RealD 3-D glasses (CPL filters) and look at a nanotexture iPad, you'll see that the nanotex layer decoheres the polarization of the underlying display, which is more like how normal (reflective) paper behaves.
