Personal protective equipment is a mandatory attribute when performing almost any construction work. First of all, buy goggles is especially important. After all, any damage to the eyeball, pupil and lens is very difficult to recover. And in some cases, the injury leads to disability. This is very easy to avoid if you choose the right quality plastic glasses to protect against mechanical and chemical damage.
Type of eye protection
Open design, where the emphasis of the entire structure falls only on the nose, has the lightest possible weight. They do an excellent job of protecting against mechanical damage, but will be useless with volatile chemicals.
The closed design is more bulky, fits snugly to the face, and creates good protection not only from mechanical solid particles, but also does not allow chemical vapors to irritate the eyes. Each option has its own advantages and disadvantages, and it is worth choosing a product, focusing on the type of work that the employee will face.
Is ventilation important?
The presence of ventilation is a prerequisite for a high-quality model of work, safety glasses. Even if ventilation is not direct, it should normally allow air to circulate in the sealed space under the lenses. In addition, properly arranged ventilation will provide:
- confident work at any time of the year;
- transparency of lenses indoors and outdoors;
- the presence of materials that absorb sweat;
- correctly positioned holes;
- direct blowing of the lenses without a directed stream into the eyes.
Plastic lenses
Modern polymeric materials are significantly ahead of glass in their technical and operational properties. Plastic is resistant to strong, including pinpoint impacts. In the worst case, debris will crack the lens. But in no case to eye injuries.
Protective plastic glasses predominantly have clear lenses. They are versatile and suitable for a wide variety of jobs, both indoors and outdoors. But, there are models with smoky glasses, or with reflecting harmful solar radiation.
