Safety glasses are used as a means to prevent dust, dirt, corrosive substances from entering the eyes. They are indispensable at construction sites, in industry and even in everyday life.

Features and purpose

Workers in many factories often wear goggles. In most cases, they are an integral part of the equipment. They are indispensable when working with chemicals and are used to protect the eyes.

In carpentry, auto repair shops, such things protect the eyes from mechanical damage. They are produced for plasma cutting, for working with a grinder. The products are suitable for the gas cutter. There are mounting models.

It is also mandatory to wear safety glasses in chemical laboratories

But such products are used not only in production - they are also indispensable in everyday life . The service life depends on the scope of application, sometimes glasses lie in houses for years, since they are used only when necessary.

Working eye protection has a lifespan. They are tested, the results of which are recorded in a special journal. When cracks, chips and other defects appear, the glasses are replaced with new ones, and the old ones are written off.

Species overview

Among the wide range of models, you can find sealed anti-fog, locksmith, heat-resistant with a light filter and with indirect ventilation, glasses, backlit options, mesh and even goggles.

Despite the possible equipment, all models are divided into two large groups: open and closed

Open

These products are sold at attractive prices. There are anti-fog and panoramic models.

For such professional products, the structure does not fit the face, hence the excellent ventilation . Glasses with direct ventilation rarely fog up, which in some areas is an indispensable quality for protective equipment.

However, because from the sides, dust and particles can enter the eyes with the wind, they do not have a sufficient level of protection when we are talking about working with a grinder.

In the professional field, open-type safety goggles with the ability to adjust the temples are used

Protective equipment for machine operators with transparent tempered glass is very popular.

Closed

The greatest degree of protection is ensured through the use of goggles. They should be used when sparks, material particles or glass shards fly away during operation.

This type of glasses must be worn when working with stone, concrete and other hard materials.

Closed glasses are equipped with an elastic band and a device for adjusting the temples . They are very similar to the masks used by divers or snowboarders.

There are products on the market that are completely made of silicone, and those in the design of which only a silicone seal is present.

Despite such a number of advantages, this type of glasses also has its drawback - they fog up a lot . Some manufacturers were able to solve this problem by making small holes on the sides, but with the advent of ventilation and the degree of protection decreased.

It is better to use glasses of the ZN type, that is, with indirect ventilation. In such designs, there are special inserts with channels in the frame. Dust particles settle in them.

Glasses of this type are easy to clean - you just need to remove the ventilation inserts, rinse them with water, wipe them and dry them with a hairdryer.

When working with chemicals, goggles are also used, but MH.

Materials (edit)

Eye safety is especially important when a person is performing work in difficult conditions. Glasses protect from chemicals, debris, glass. Such means of protection are irreplaceable in the woodworking industry and construction.

Safety glasses can be tinted or clear . You can choose the color of the lens based on your own comfort. If you have to work in the bright sun or with welding, then it is better to choose dark glasses.

Products can be in plastic or metal frames.

It is advised to purchase models in the design of which side windows are provided.

Each model offered on the market has its own place in the safety rating . This rating means that the lenses have been tested to withstand impact. The more expensive the glasses are, the more mechanical stress their lenses can withstand.

On the market, you can find models with adjustable straps or anti-fog lenses.

The user's choice should be based on what degree of eye protection is required. In this case, it is worth relying on the scope of the product.

The described means of protection are of several types:

• glass;
• plastic;
• plexiglass;
• polycarbonate.

Scratches do not remain on the glass over time, but the problem is that users often complain that the material is heavy and causes discomfort. Glass is also prone to fogging.

Plastic is lighter when compared to glass . It is also less prone to fogging. The problem is that scratches quickly appear on it, resulting in reduced visibility.

Plexiglass is widely used in medicine and aviation . It owes its popularity to its high strength. If it is destroyed, then without fragments. The disadvantages include poor resistance to solvents and other chemicals.

Polycarbonate is another option for goggles . It does not fog, scratches and is lightweight. These glasses are more durable than the other two options, but they also cost more.

Marking

The marking of goggles is well described by GOST 12.4.013-97, where O means open glasses, OO - open folding, ZP - closed with direct ventilation, ZN - closed with indirect ventilation, G - sealed closed, N - mounted, K - visor and L - lorgnette.

If double glazing was used in the design of the product, then the letter D. is added to the marking. In the presence of an adjustable lintel, a capital P. is added.

The frame is also marked, it consists of letters of the Latin alphabet and numbers. An example is 7LEN166xxxFTCE.

The first character is always the manufacturer, the next two letters and three numbers are the European standard. The three XXXs define the area where the product can be used.

Further, if 3 is indicated, then the glasses are protected from liquids, if 4 - from particles larger than 5 microns. 5 indicates the presence of protection from gas, 8 - from an electric arc, and 9 - from molten metal.

The mechanical strength of the lenses is indicated next . If there is a letter A, it means that they can withstand the impact of particles moving at a speed of 190 m / s, if B - 120 m / s, F - 45 m / s. In the presence of a capital T, we can say that the product in question can be used under extreme temperature conditions (from -5 to + 55C).

The identification code of the filter is indicated in the marking on the glasses: 2 means protection against ultraviolet radiation, if it is 2C or 3, then this is additionally and good color rendering . When there is protection against infrared radiation, the number 4 is indicated, if the glasses protect against ultraviolet radiation, but without the infrared specification, then put in the marking 5, if with the specification, then 6.

You can also find out about the degree of shading: 1.2 are completely transparent glasses, 1.7 are designed for working in open space, 2.5 have smoky or brown lenses.

Scratch protection is indicated by a capital K, anti-fogging by an English N
