Choose a comfortable frame
Selecting a frame in terms of its weight, shape, and size to meet your individual needs is extremely important. We consider the user's individual needs and provide comfortable eyewear with a fashionable design that can be worn for a long stretch of time.
There is four frames style for your selection as above, Frame 33/36/52/301/304
VLT (Visible Light Transmittance)
In visible light, the attenuation of light by a filter is defined as visible light transmittance. According to ANSI Z136.7, the
testing of VLT is determined by a standard light source. If VLT is less than 20%, users should remain in a light area and ensure their working environment has extra illumination. the higher the transmittance, the better the visual view.
Choose the relevant wavelength
The laser safety glasses cannot be used against other wavelengths of lasers other than those mentioned. For more details, please consult with the manufacturer for the most suitable glasses.
Choose a high OD protection level
OD laser filters were designed to reduce specific wavelengths into the eyes while allowing some normal light to pass through the eye. This absorption or filtering capability of the lens is expressed via OD, which is the attenuation of light through the optical filter.
When we are using a laser machine, it emits specific wavelengths or radiation of several wavelengths simultaneously. Some of these wavelengths can be normally seen by us, while some are invisible to the human eye, such as the ultraviolet light and the infrared light. Invisible light does not mean that our eyes will not be hurted. Ultraviolet lasers (100 - 400nm) usually damage the cornea and the lens. Lasers in the 400 - 1400nm can directly penetrate the human eye lens and damage the retina and even the optic nerve, causing irreversible damage. Lasers above 1400nm cause similar damage to the human eye as Ultraviolet laser, mainly to the cornea and the lens. Due to the focusing characteristics of the eye, its sensitivity to lasers is 100,000 times that of the skin. Long-term exposure to the laser radiation environment can cause irreversible cumulative damage to our eyes and even blindness. The role of laser filters is to protect the eyes from damage of specific wavelengths, significantly weakening specific wavelengths or reducing them to below the maximum permissible exposure MPE value (Maximum Possible Effect).
For laser power below 10W, protective products with optical density OD4+ can be considered.
For laser power within the range of 10 - 100W, protective products with optical density OD4+ - OD5+ can be considered.
For laser power within the range of 100 - 800W, protective products with optical density OD6+ can be considered.
For laser power within the range of 800 - 1500W, protective products with optical density OD7+ can be considered.
For laser power above 1500W, it is recommended to choose protective products with optical density OD7+ or higher.
Multiple protections should be adopted when necessary.
The above can only be used as a general reference. For specific situations, we need to comprehensively consider more relevant parameters of the laser itself and the specific application scenarios.
