Protective goggles: So that nothing comes to mind!The protection of the eyes is very important in many activities, in workshops, but also in laboratories. Protective goggles, depending on their design, can protect against particles, caustic or other substances that are hazardous to the eyes and against radiation. Overall, harmful effects on the eyes can be caused by mechanical, electrical, optical, thermal or chemical stimuli.
Depending on the hazard, the correct safety goggles must be selected. The requirements for protective goggles are regulated in DIN EN 166.
The markings A, B, F and S stand for tested safety discs against general mechanical influences.
In the field of optical radiation, there are e.g. Goggles with protective filters against ultraviolet radiation, infrared radiation or against lasers.
Excessive UV radiation is harmful to the eyesFrequency ranges of UV radiation are from 315 to 380 nanometers for UVA radiation, between 280 and 315 nanometers for UVB radiation and between 100 and 280 nanometers for UVC radiation.
The shortest wavelength radiation is thus the UVC radiation. It is most dangerous to humans, but is almost completely filtered out in nature by the ozone layer. This is one of the reasons why the ozone layer is so important, among others. Damage to the ozone layer therefore causes increased UV radiation.
In contrast to UVC radiation, the UVA and UVB rays are not absorbed by the ozone layer. However, both types of radiation are excessively harmful, both to human skin and to the human eye. UVB radiation, for example, which causes a sunburn, destroys the skin cells in the event of excessive and prolonged irradiation; moreover, it can lead to the destruction of individual DNA strands. When exposed to extreme or prolonged UV radiation, such as welding without goggles or a welding helmet, damage to the eye's eye tear layer occurs on the eye is. In addition, the radiation damages the cells of the upper corneal layer. This damage is often only temporary, but in the long term the UV radiation promotes irreversible corneal degeneration. It can also cause a cataract or favor its emergence. Likewise, a conjunctivitis may arise. Therefore, it is so important to wear appropriate protective goggles with UV filters in activities where UV radiation has a long or intensive effect on the eye.
Spectacles with a UV 400 filter absorb UV radiation in the frequency range of 280 to 400 nanometers wavelength, which includes all UVA and UVB radiation.
Goggles with UV 380 filters filter ultraviolet radiation in the range of 280 to 380 nanometers, which also covers the UVA and UVB frequency range.
However, as some experts now assume that even UV light with wavelengths between 380 to 400 nanometers can be dangerous, UV400 filters in sunglasses and goggles are often recommended.
We offer different versions of goggles in the field of mechanical eye protection as well as UV filters.
In addition to the goggles, we also stock welding protection, work gloves and general work clothes.
