The limits of the display technology are not being reached in consumer
devices.  A direct laser-on-retina display is perfectly capable of
making you squint...but we just aren't getting those in consumer devices.

Although our flight sims have 'G-LOC' (g-induced Loss Of Consciousness)
simulation (because the military buyers insist on it). We are told that
pilots almost always turn it off when training because it's NOT realistic.
Not that it's not realistic graphically - it is.  The problem is that
in the real world there are things you can do to reduce that effect
(various physical exercises that push blood back into your brain) that
don't work in the simulator because we can't easily detect how well
the pilot is doing them.

The point is that you shouldn't impose an effect (like glare) that
you could react to in the real world (by for example by shielding
your eyes with your hand) - unless your possible reaction to it is
also simulated (eg with a head tracker and a 'digi-glove').
