Laser shining eyes, with eyes, cornealdamage of retina and lens, the eyes filled with DB, decreased eyesight, andeven loss of call, and the eyes of the laser damage is cumulative, do not payattention to today, tomorrow will bring serious consequences, so the protectionof the eyes is the most important. Do you need to wear glasses, at least on thetwo laser output parameters: maximum exposure period, laser wavelength andoutput power or output energy, as well as the corresponding maximum promisedshine though (MPE).
Some of the most important laser glasses isusually made of polymer material and optical filter, optical absorption data ismade, perhaps the use of coloured glass, or coating on the lenses, theyselectively absorb attenuation or reflection specific wavelength, and as muchas possible through visible light. The existing protective glasses are dividedinto the following types: the common glasses type, the non transparent frame ofthe light proof type, and some translucent border of the semi anti side lighttype and so on.
The parameters include: laser protectiveglasses, protective wavelength or wavelength scale filter on the outputwavelength of the laser optical density, protective glasses on the visiblelight transmittance, laser damage threshold of the protective lens (maximumirradiance) and lens curvature. Not the same as the laser radiation of thelaser wavelength is not the same, need to wear protective glasses are not thesame, so the protective glasses should be marked with a protective wavelength,usually marked with the maximum power laser radiation wavelength.
The laser technology developed veryrapidly, more and more widely used in many occupation, are used, so sometimesneed to wear protective glasses, if we do not pay attention to today, tomorrowwill bring serious consequences, so the protection of the eyes is the mostimportant.
