How do laser glasses protect our fragile eyes

In ourlives, for the use of the laser reached a high level, but still can not avoidis the laser damage to us, is still so big. So the timely use of is very important.

   Today, for everyone to talk about laserdamage to our glasses. Eyes are the most sensitive organ of the human body tothe laser. Due to the characteristics of the laser, the energy can beconcentrated in space and time. By focusing the lens with the role of the eye,so that the retina in the unit area of the laser irradiation energy than thecorresponding corneal incident volume of nearly 100,000 times.

   Lasermonochromaticity is very strong, in the fundus of the color difference is verysmall. Because pulsed laser injury is much faster than blink reflex (human eyeblink time is usually 150-250ms, and pulsed laser can be as short as 10ms),coupled with extreme moments, in a very small area, the energy Concentratedrelease, even low doses of laser irradiation can lead to serious damage to thecornea or retina.

   Bylaser damage, the light appeared in the retina Ling solid edema lesions, forthe gray, the course of 1-2 weeks, edema subsided. Severe cases will be retinalburns, there hole, bleeding, duration of 3-4 weeks, once the bleedingabsorption, leaving pigmentation and the formation of bruises. When the lesionis related to the macular area, the vision is seriously degraded. Aconsiderable number of people fell to 0.1 below vision. The great harm of thelaser, we must promptly prevent the laser to our damage is irreparable.
