In life we have numerous problems ofdevelopment and the life, for we are the most important thing in life is tohave a healthy body comfortable to enjoy life. Laser glasses found that we havebeen able to because the use of laser in the comfortable enjoyment of life, buta laser is dangerous and threatening but we can't avoid the problem. Theinteraction of laser and biological tissue, main show is thermal effect andphotochemical effect, mechanical pressure effect and the effect of theelectromagnetic field.
Laser tissue damage and damage to humanbody, mainly depends on the wavelength of laser, light source type, means oftransmission, incident Angle, radiation intensity, according to time and thecharacteristics of biological tissue and spot size. Laser damage of targetorgans mainly for eyes and skin. The laser damage to the skin, mainly caused bythe thermal effect. Mild injury characterized by erythema and pigmentation.With the increase of irradiation dose, can appear blisters, fade, coking andskin ulceration. 250? 320 nm ultraviolet excitation light, can make the skinproduces photosensitive effect. When subjected to high power laser radiation,can also through the skin to deep organ damage.
Hope everyone can understanding of laserwith clear formal, think we not only need the laser to the laser glasses tochange our traditional way of life is optimized, more important is we need touse laser for laser in the life the correct understanding of correctunderstanding.
