Trust many people now know our laserprotective glasses, also strengthen the protection of our eye on the job cutsfor eye damage, so not only can enhance the use rate in use, use of laserprotective glasses together very well in the use of the effect, can let morepeople choose laser protective glasses our. In this small series is recommendedwe use our laser protective glasses.
Eyes are the most sensitive organ of thehuman body to the laser. Because of the characteristics of laser, the energy inspace and time to gather height. By focusing on the lens with the eyes of theeffect, so that the retina in the unit area of the laser illuminated by theenergy than the corresponding high corneal incidence of nearly 100 thousandtimes. Laser monochromatic good very strong, in the fundus of the colordifference. Because pulse laser injury is much faster than the blink reflex(eye blink reflex time is usually 150-250ms, and the pulse laser can be asshort as 10ms), plus pole moment in a very small area, gathering energyrelease, even low doses of laser shine can also cause serious damage to thecornea or retina.
The laser light damage, retinal edemadamage showed Ling solid spot, gray and white, 1-2 weeks duration, edema ofrecession. Severe patients will be retinal burns, presenting a split hole,bleeding, the course of 3-4 weeks, once the bleeding absorption, leaving thepigment calm and constitute a blood stasis. When the size of the lesion isrelated to the macular area, the vision is severely reduced. A person withappropriate vision is reduced to less than 0.1.
