What magnitude of laser power would you estimate to be required to
cause retinal damage at say 1 mile for what period of time?

If I may change to a different laser wavelength with a conforming
lens, a 1 megawatt laser will cause nearly instantaneous, and irreversible,
damage at ranges beyond one mile.

So you figure that 1-megawatt is the MINIMUM power necessary? Given
the fact that the majority of homes in the US are served by a
24-kilowatt (2.4% of a megawatt) electrical service, it's not likely
that any retinal damage is possible without browing out half a
neighborhood. :-)
