Quick tip for users of non-rlcd screens or iphones
If you find it difficult to look at screens in general, and color accuracy isn't a concern.
For laptop/monitor screens, get yourself a "privacy screen". It does much more than dimming the screen, too long to get into in this post but highly recommended.
For some, if you get a TN matte monitor + a privacy screen viewed from matte side. Not perfect, however very close to comfort of RLCD without the price tag
On iPhone, might help if you set "Reduce White Point" to 50% or higher.
