Specification: Product name:Red Protection Glasses Protection Wavelength: 200-540&800-2000nm Protection Features: All-round absorption Visible Light Transmittance: 60% Optical Density: OD 5+ Body color: Red Size: Approx. 18 x 5 x 5 cm Laser injury for eyes Eyewear is the body's most sensitive organ of the laser. Characteristics of the laser, the energy in space and time allows the highly concentrated. As a focusing lens glasses effect, so that the unit area suffered retinal laser energy than the amount corresponding to the high incidence of corneal nearly 10 times. Good monochrome laser strong in the eyes of the very small difference. Because pulsed laser injury is much faster than the blink reflex (eye blink reflex time is typically 150-250ms, while the pulsed laser can be as short 10ms), coupled with the extreme moment, in a very small area, energy focus on the release, even low doses of laser irradiation can cause serious injury to the cornea or retinal. Different wavelengths of the glasses lesion WavelengthDivision Wavelength Range (nm) primary lesion UV laser 180-400 cornea Visible laser 400-700 lens Near-infrared laser 700-1400 retina choroid. Lens In the (far) infrared laser 1400-10600 cornea The principle of laser glasses Laser protective glasses with light absorption principle: its light is not selective, it is safe PROTECTION diffuse light; incident angle of the light source is not selective, specific bands can be full protection of the laser and the light, the light and rapid response, decay rate is higher, the surface afraid of wear, even with scratch, does not affect the light security. Package included: 1 x Red Laser Protection Glasses
