After Laser Attacks, Pentagon Spending $200M to Protect Pilots’ Eyeballs
The U.S. Air Force is planning to spend nearly $200 million on special glasses and visors to protect pilots’ eyes from dangerous lasers like the ones the Pentagon accuses China of firing into the cockpits of U.S. warplanes. (www.govexec.com) 更多...

A laser seeking HARM would discourage the practice
Maybe a little primer on lasers, and laser protection would help.

Why is there no pair of glasses covering all my lasers?
The radiation that is visible to humans lies between 380–780 nm
(the exact limits are different in each person). In order to cover all lasers
you would need a material that does not transmit any radiation for visible
radiation, which means it is completely black. When you block all visible
radiation, the only wavelengths left are invisible to the human eye. If
you have several lasers in this area, then it is necessary to use several
pairs of glasses. But even if you do not want to completely block all
wavelengths or have ’just a few wavelengths‘ to cover, the glasses may
be too dark. Usually the protection within a material slowly increases
until it reaches the required protection level at a given wavelength.
This means that it not only covers the required wavelength, but also
areas below and above it (with lower Optical Density). Therefore, if you
want to cover several wavelengths in the visible spectrum the Optical
Density curves will overlap, resulting in dark filters or glasses.

It would be nice to see that same coating be made available for non-military folk as well.
Some people just like to watch the world burn... I bet one of them just wanted to watch a plane crash after they shined that laser to the planes...
What are you trying to say? It's disturbing by all accounts.
That is exactly what he said.
