"Safe" l@ser energies

Regarding the "safe" energy levels, does anyone know how what the assumptions of the pupil size are? If the "safe" estimates are based on a normal (day adaptation) pupil, wouldn't the resulting figure be an overestimate for a dilated (night adaptation) pupil?

According to wikipedia, a normal diameter of the entrance pupil is about 4mm, ranging from 2mm (bright) to 8mm (dark), so the underestimate might be with a factor between 4-16.

Just my SEK .10.
