in tattoo removal you must use an Optical Density level of at least 7 - this means that they occlude those particular wavelengths by a factor of 10 to the power 7. I.e. 10,000,000.
The current value of the MPE for eyes at 1064nm indicates an OD of around 6.5 (for nanosecond pulses). Hence, stick to 7 and above to keep your eyes safe folks!!
