I just tested my 455nm against the DeWalt brand laser enhancement glasses I purchased ages ago for green protection. I was measuring 190mW without, and the lens brings it down to 2-5mW (some of that being the heat from my hand being near the sensor. I recorded a video to follow...Quick check of my red enhancement glasses, and at 405nm.
Not much light passes through the red plastic.
Input: 4mW
Output: 30uW, or less (quick measurement with my 3Watt Ophir Head, Vega meter.
Therefore OD of them at 405nm ~ 2 to 3.
