With the threat of Eye scan cams looming on the horizon, data

lenses used to reduce eyestrain and headaches. They

Anti-reflective coatings WKTE
Many coatings consist of transparent thin film structures with alternating layers of contrasting refractive index. [a1, Jun 17 2022]

use to reduce eyestrain with such properties?
||Non-reflective coatings are good, but I think it would be
better to use the shape instead. A full hemisphere might work
(reflecting too much of the world so the screen reflection
would be small) or perhaps a severe slope, so the persons lap
is what is reflected. Transmitted light wouldn't be affected
(much) if the inside & outside surfaces are parallel.
