1. anti-solid ground is goggles, used mainly in defense of metal or sand and debris, such as mechanical damage to the eye. Glasses and frames should be consistency, resistance. Around the frame, fitted with a lid, on which it should be. Optional tempered glass protective lenses or Copper braid, glass resin protective glasses.
2. anti-chemical solutions for safety glasses, mainly used in defense of chemical irritation or corrosion damage to the eye. Optional common flat light lenses, frames should include, in the case where the solution was poured. Typically used in laboratories, hospitals and other places, glasses for general medical, General.
3. radiation protection glasses, for defensive-minded
Protective eyewear
Protective eyewear
The dangers of UV radiation on the eyes. Mirrors can reflect or absorb radiation, but by special glass must be visible. Lenses or chrome-plated, nickel and Mercury metal foils Bank, reflecting radiation; Blue
lens absorbs infrared radiation, yellow and green lenses and absorb UV
light and infrared light, colourless lead lens absorb x-rays and gamma
rays. As joint welding glasses, lenses, light feet demands is low, so the color lenses more spot-color ink, mainly; laser
protection glasses, as its name suggests, is a laser radiation glasses
can prevent, so the lens is high, how to select and damping rates light
and reaction time to light and low density and light effect, various
Nano (nm) laser for the purposes of different lenses.

certification authority should regularly can refer to agencies:
National Center for optical glass products supervision and inspection; standard
shocks may refer to: United States ANSI z87.1-2003 occupational and
educational personal eye and face protective devices.
The patent must be complete, or at home, "sprout", as generic products, the quality is absolutely no warranty. Certification
of the product must be clear, brand distribution companies, suppliers,
OEM, production date, certification, inspection report in hand.

sunglasses, sunglasses, visible light transmittance of approximately
20% for a better absorption of ultraviolet and infrared. Ash-pale green, pale, weak tea and other color, shade and used to snow and protective glasses. Light grey lens color minimal impact identification; superficial glasses of tea makes it look darker, making Green by reducing; light green lenses made by reducing red light the sky.
2,
gas welding goggles that mirrors the dye used mainly iron oxide, cobalt
oxide, yellow green, fully absorb to 500urn wavelength of light waves,
visible light transmittance is below 1%, may have only a small amount of
infrared light pass. Lenses using autogenous welding operations.
3,
welding goggles, welding produces UV light, brief exposure of the
eyeball cornea and conjunctiva caused by tissue damage (up to 28nm
manufacturing light the most critical). Strong infra-red very easily cause clouding of the lens. Welding goggles used to intercept above the rays infrared and ultraviolet. This
lens is based on optical glass, such as iron oxide, cobalt oxide and
chrome oxide pigment, but adding a certain amount of cerium oxide to
enhance the absorption of UV LIGHT. Is green or yellow-green appearance. All intercept transmission of ultraviolet, infrared, visible light transmittance of 5% < around 0. 1%."sdwrx3ssa3xg"
