How feasible is it to just implement this in hardware? That is, a sheet you can place on your iPad screen which attenuates bright whites and tints everything red. Might be the 80/20 solution in this case.
- starpilot 14y agoSome amateur astronomers have red-lens glasses for this purpose. Also allows them to run inside a lit house without spoiling their nightvision.
- mmcnickle 14y agoI've personally seen astronomers use red perspex covers for their laptops/phones as a way of preserving their night vision in the field. I imagine that there could be some edge cases where contrast could be low etc. But it's a cheap solution.
- niels_olson 14y agoHi, I'm the author of the post. We use this hack on the bridge of Navy ships. The red density required is pretty significant (the plastic we used was a little thinner than a #2 pencil). We would velcro it over the screen. The velcro leaves a gap which creates a fairly significant light leak around the edges. First iteration, so better, but a long ways to go. Comparing that to Blacktree's nocturne, software is at least a significant part of the solution.
