Hey Pi, I think you are correct on your math.
I think a quality pair of OD 4 would be fine.

I think your math is off by two zeros, someone correct me if I am wrong, doesn't OD 4 reduce the light to 1/10000th and OD 5 to 1/100000th, I am sure I read this somewhere. Or am I off by one zero?

Anyway OD 4+ is good enough for a 3.2W laser, at least for viewing the dot up close, but at 3.2W I wouldn't trust just any glasses to protect from a direct hit.

Something seemed off. I was using the equations from here:

Certified Laser Safety Glasses

Confused the 0.001% with actually reducing it by 1/10,000th when it fact,
OD5 reduced by a factor of 0.00001, 1/10,000, 0.001% or a 3.2W laser to 0.032mW or safe levels. It's one of those days.

The equation is:

I_out = I_in * 10^{-x}

where Iin is the input power, Iout is the output power, and x is the OD.

OD 4 --> 10^-4 = 0.0001. I_in = 1W --> I_out = 0.1mW

For green lasers, the OD of goggles such as ARG-type goggles may seem really high (OD7), but it makes it a lot easier to work with for aligning and stuff.

I didn't mean that but I just read first thread about the eye safety and posted my opinion.

Hi, Safety eyeglasses are one of the finest protection against eye damages. So, shield your eyes from countless threats either you are indoor or outdoor. Besides, safety specs have a significant effect on long-term vision health. Consider your activities of each day that may lead to eye injuries. So, complete your kit of personal protective equipment with high-standard safety glasses. This is because they are the ultimate protection from any foreign debris.
