The use of data inthe day of diversity is now becoming more and more visible, and we should alsobe able to see in the day the diversity and necessity of the use of thesematerials. In our laser glasses looks like we use enthusiastic about lasermaterial and worship must be very serious, but we even in the use of laser, butreally to know the exact laser now? Application of laser material in our lifehas incomparable important, but we are always no laser recognize the truthclear, this appears to be a risk in the case of our laser glasses.
The degree of laserdamage to the eyes is not only related to the different wavelength of thelaser, but also to the total light energy, energy density and power density. Inthe type of laser, when the laser power density of visible or near infrared isvery low, it will not cause acute damage to the eyes. The primary reason isbecause the laser power density is low, though the arrangements under theretinal laser photon energy gradually becomes hot, but the heat throughmolecular vibration to heat to the surrounding arrangement, and then spread tothe eyes of the outside; microvessel and on the other hand can be covered withheat to the omentum in underlying choroidal microvascular, follow in the bloodcirculation and then distributed to the eye to. Therefore, the whole eye retinato temperature significantly add, or slightly change in scope is still tepid,completely harmless to the eyes. Retinal damage depends on the power and time,such as when the visible or near infrared laser power density were added, theheat induced retinal tired faster than the heat dissipation rate, or powerdensity is not very high, but the retinal absorption time is too long, theretina under photon flow parts of the temperature will add more exposure timelong, add more temperature, adding more temperature than normal temperature,eye 10 degrees, will lead to retinal damage.
The primary andpractical laser has always been the primary protection of our days, but alsothe source of our days forward and diversification. In the days we alwayscannot lack of a variety of diverse data use, science and technology is thefirst productivity. We should be active in the day to find that the damagecaused by the improper use of the laser material. Attach importance to theprotection of their own is also very important!
