Is there a tunable visible wavelength optical filter for exclusively filtering intense coherent laser light?

The problem is the dazzle effect overloading the retina. This has long been a problem for pilots in a (theoretical) nuclear war scenario, where the visor needs to blank within microseconds.

However, the modern problem, apart from laser "toys" is laser dazzle weapons. Once such approach to protection is this. Not perfect, but vastly cheaper than protecting from a nuclear weapon flash.
