I don't think you quite understand.
On Quora, there's a question:
"How quickly can a 10W 450nm laser blind a person or animal?"
Quote:
"There would be a 50% probability of permanent damage in about 300 nanoseconds. I am not sure whether you call that blinding a person.
In about 500 microseconds, a large thermal burn will occur on the retina, causing a permanent large blind spot, a blood spurting ulcer on the retina, severe pain, and permanent damage to the vitreous humor.
If you missed getting the beam directly into the eye, the beam will hit the sclera, eyelids and other tissues. Within a couple of milliseconds, painful burns will result."

"Instantly. 450nm ~blue/near uv. Specular reflections (reflection off something ball shaped] will find any eye looking. 10W is a LOT of power and even a glint will instantly cause blind spots if not outright blindness. Yes, the damage will be permanent."

The 50 kilowatts (kw) laser used in US army anti-drone stuff is 50,000W: or approximately 5000 times more powerful than the hypothetical 10W laser example cited above.
It doesn't matter if the optical sight used in the fire control system is coated with an anti-laser coating good against that laser; it just means it takes 50 milliseconds longer (number out of nowhere) to burn through to the internals of the system.
At that point; the best thing the optical system can do is to fail gracefully and go "dark" before the damaging laser energy can be transmitted to the crewman's eye(s).
Honestly, at this point; the best defense against laser attacks is to be moving fast enough and erratic enough that it becomes almost impossible for the laser tracker to lock onto an optical/thermal sight or vision block.
