Main organ of concern; range of effects as below starting with the most severe to the least; damage from  thermal / photochemical / photomechanical process
Tissue vaporization
Retinal hemorrhage / ocular holes
Retinal burn / corneal burn / irreversible scotoma/minimal visible lesion
Histological damage / irreversible scotoma / cataract
Nominal ocular hazard distance (NOHD)
Distance from<unk>  source which the intensity of a single<unk>  beam becomes safe by not exceeding the maximum permissible exposure<unk>  is dangerous if viewed from a closer distance than this
Can be calculated if power (mW), divergence (mrad), and diameter at aperture (mm) is known
Flash blindness / after images / reversible scotoma
visual loss temporary
lasts seconds to minutes
similar to flashbulb effect
Glare/dazzle
no permanent damage results
similar to driving into the setting sun
Distraction

Second organ of concern; effect more dependent on wavelength of<unk> 
thermal burns - IR, visible, UV-A<unk> 
photosensitivity - Visible, UV-A<unk> 
darkening - UV-A<unk> 
accelerated skin aging - UV-B
skin cancer/erythema - UV-C
Laser injury
Cement burn
Penile amputation
Hazmat exposure
Tar burn
Corneal abrasion
Conjunctival abrasion
Gun shot wounds
