With the threat of Eye scan cams looming on the horizon, data
security requires constant adaptation to emerging security
threats. These are glasses one can wear while working at a
computer, similar in appearance and function to those blue light
lenses used to reduce eyestrain and headaches. They
have a
nonreflective outer surface to prevent your lenses from revealing
via reflection what it is you are looking at onscreen.

What is it about the outer surface which makes it non-
reflective? |
|

[a1] are you aware of any glasses marketed for computer
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. |
