About eye protection

Eye protection must be used if the work is not otherwise can be organized and carried out so that damage to the eyes should be avoided. Eye protection protects the eyes from one or more of the following types of exposure: Mechanical, chemical and radiation.


Considerations for eye protection

Always choose eye protection for the job you have to solve. Then focuses on comfort, because if safety glasses are comfortable they are not used!

Underestimate nor designed, select like a security glasses to match your personality.

The range of safety glasses is large, so there is no reason to compromise. One model does not fit all, and it is always important to feel comfortable with his safety glasses. Use beskyttelsesbrillen as long as you are at risk - even for short-term work. It is "typical" at the short routine work that damage occurs.

As eye protection comes in many forms and with different characteristics, you should even ask you one question:

"What protective glasses must protect me from?"

  • Overall protects the different types of eye protection against three influences: mechanical, chemical and / or optical effect.

  • By mechanical means flying splinters or particles, inter alia, grinding or polishing work.

  • By chemical action means contact with harmful substances.

  • By optical effect means welding, display terminal work and exposure to laser radiation.


For protection against mechanical impact are:

  • Framed glasses with side protection

  • Goggles

  • Face shields and visors

  • Sandblasting Helmets


For protection from chemicals are:

  • Goggles

  • Face shields and visors

  • Hoods (with integrated eye protection)


For protection against optical effects (radiation exposure, light, laser and heat) are:

  • Framed glasses with side protection

  • Goggles

  • Face shields and visors

  • Frame Glasses, capsule glasses, facial and welding screens

Eye protection is also available in different materials with different properties.

Typically:

AcetatePlastic material, particularly suitable for working with chemicals and solvents.
Polycarbonate (PC)Tough, strong, and the material with the greatest mechanical impact resistance. May, however, be easy to scratch, so they are often treated with a surface hardening. Protects against UV rays.
Laminated glassTwo thin plastic sheets bonded together with a plastic film. Poor mechanical strength, but very scratch resistant.

Step 1. Select eyeglass type

Here are the different types of safety glasses:

Odoo - Sample 1 for three columns


Ordinary safety glasses with side shields: The bars are often adjustable in length.

Odoo - Sample 2 for three columns


Modern safety glasses with embedded windows in panoramic lens, which can often be replaced

Odoo - Sample 3 for three columns


Visit glasses or so-called "Cover spectacles", which in some cases can go outside of normal glasses. Sometimes called "grinding spectacle".

Odoo - Sample 3 for three columns


Capsule glasses ("goggle" or "sproggle") or wrap-around covering the entire eye socket area: Most glasses can be worn during this type of safety glasses, available with direct or indirect ventilation.

Odoo - Sample 3 for three columns


Visor, usually worn using. Brow guard or other device. Face shields are generally made of polycarbonate (PC), which has the best impact strength but the least scratch resistance, or Acetate (AC) having a lower impact strength, but greater scratch resistance and better chemical resistance than PC.

Step 2. Determine properties

Safety glasses are available with different properties such. clear colored lenses, mirrors, lenses or safety glasses with reading area or strength.

Safety Prescription glasses

Anybody who needs corrective lenses can now get safety glasses in a stylish sporty design and glass in different colors.

The concept consists of an inner eyeglass lenses that can be easily mounted on an outer spectacle.

RX insert ™ system, where the spectacles strength is located in the effort, and thus protected by outer goggles.

If the outer goggle is damaged, the inserts are simply moved over to the new outer spectacle, which also comes with both clear as dark and yellow glass. The insert can be supplied with single vision, with reading area and bifocals.

In addition, of course, a goggle, i.h.t. EN 166, with strength. At D-S, we can offer a range of approximately 40 different models.

All safety glasses provided with "4A coating": Anti Dug, anti-static, anti-scratch and anti-UV 99.9%.

Eyeglass frame is made of hard plastic, metal, or titanium. The glasses are supplied with cleaning cloth and glasses case, while glass equipped with such. color changes are available on request.

For all prescription glasses, it is obviously essential that they are produced by the same vision test as the user's private glasses, so that no problems can be switched on and off own glasses.

The normal procedure is that the user through visits of our consultant selects an eyeglass frame, give a copy of its vision test from the optometrist or ophthalmologist and get a picture taken with the selected glasses on, so that the exact interpupillary distance determined.

Approximately 3 weeks later comes the goggle lenses with strength.

Expanded knowledge on Safety Glasses (Eye protection)

When to use eye protection? And what eye protection? Read more here.

Eye protection must be used if the work is not otherwise can be organized and carried out so that damage to the eyes should be avoided. Eye protection protects the eyes from one or more of the following types of exposure: Mechanical, chemical and radiation.

Important and useful information

  • Eye protection can also be an integral part of a respirator.

  • Eye protection is personal protective equipment as eye protection must be adapted to the person who uses it, and therefore do not necessarily want to sit properly on another person.

  • Eye protection must be CE marked. Applicable standard. For eye protection with interchangeable protective glass or visors, then both the frame and protective glass as individually CE-marked.

  • There must always be accompanied by instructions in Danish, which provides information on, inter alia, eye structure's protective properties.

  • If you already wear glasses, protective glasses must be large enough that there is room for glasses, or you must use eye protection with corrected glass.

  • Adjusted protective glass must be CE-approved together with the frame, and it must be individually CE-marked. Eye protection structure frames, lenses or glasses may be made of different kinds of materials, not just impact resistance, and it is therefore important to choose a spectacle of the material to suit the actual application.

  • The material can be treated in different ways, so that it achieves various properties, for example, it may be treated antifogging, surface hardened, shatterproof, tinted and antistatic.

  • Acc. EU The standards are symbols of eye structure's mechanical and optical properties as well as the scope and the symbols must stand on protective glasses (frames and lenses).

  • If you combine frame and protective glass with different characteristics, since it is always the lowest ranking symbol, which applies to all protective glasses.

  • Check before using that eye protection is in working order. Scratched and damaged protective glass must be replaced.

  • Always read the instructions carefully before use.

  • It is the employer's responsibility that the employees are provided with suitable eye protection, and that it is being used at work.

  • It is the employee's responsibility to use eye protection, where the work requires it.

The Lights Effect

The light is defined as electromagnetic radiation - a type of radiant energy. There are many types such as ultra-violet rays (UV), infrared (IR), radio waves and x-rays. We can only see a very small part of this spectrum of radiant energy. The part is called visible light. Any kind of radiation has its own characteristic wavelength.

UV, visible light and infrared wavelength is very small in its size and is measured in waves known as nanometers; 1 wave = 1nm = 1,000,000-part mm = 4 atoms

The illustration below shows the visible light range and the three areas where the energy from, respectively, UV, blue light area and IR can cause damage to the human eye.

How does radiation impact the eye?

The cornea affected by ultraviolet light primarily from the distance area and in the middle-infrared range. damage to lens of the eye (iris) caused by radiation from the UV region of origin and infrared medium range. Other harmful rays are not recorded by the cornea or lens of the eye, but focuses directly on the eye Retina. This is also the case with the dangerous blue light range and IR nearby (photochemical damage effect).

The retina has a very hard time to heal; even the low-energy levels are known to cause damage to the retina. Other factors involved in the eks.vis outdoor work. In bright sunlight may blanking be a requirement. A tinted filter, which makes it pleasant to the eye and protects against eg glare from light reflections, may also protect against UV and blue light range as well as the Near Infrared range (Sunlight = 46% of the sun's radiant energy reaches the Earth's surface).

Other complications may arise from exposure to radiation from the IR range. IR radiation, together with blue light range lower limit of the eye's resistance to photochemical damage effect. Similarly, IR lower limit of the eye's resistance to UV damage, as neither the cornea or lens of the eye is cooled by the blood. Protection against IR can also reduce eye fatigue as protective filter reduces the amount of heat as such rays dishes on the retina.

Harmful rays

Safety glasses are doubles protective

While many relate to the primary function around safety goggles, namely the protection of the eyes from splinters, dust grains and other fragments, so has the medical world indicated another area that should be observed. Radiation from the infrared, ultraviolet and blue range, as indicated above, weakening eyesight, cause accidents at work and even cause blindness with age.

Ultraviolet radiation 180nm - 380n

Ultraviolet light can not be seen by the human eye and is otherwise of higher energy than visible light. Ultraviolet radiation gruppéres in three regions: UV-A, UV-B and UV-C.


UV-A (315-380nm) 
Is the closest to the visible light and has less energy in the UV region. This form of light radiation is in the sunlight and cause sunburn ("Brown"). In overly cases, it may cause a temporary loss of vision (snow blindness) and at worst inflammation of the cornea.


UV-B (280-315nm)
Also available in the sunlight, but has more energy than UV-A and can cause "arc eyes" and vigorous burning of the skin during long term exposure. UV-B can easily cause inflammation and other eye damage.

UV-C (100-280nm) 
Is not usually found in sunlight. Have a lot of energy and is dangerous. Available in many places in industrial environments such as electric arc welding.


Infrared radiation 780 nm - 1800 nm

Infrared light area is low-energy relation. Visible light range. Often grouped in two areas:

Near-IR (780 -1400nm) and Mid-I (1400 to 1800 nm). As by UV radiation, the infrared light radiation is not visible to the eye.

Near-IR-radiation can reach the retina and damage it.

Mid-IR is dangerous to the cornea and lens of the eye.

Both are present in sunlight and in many industrial areas: welding and melting processes such as glass and steel production.

Notes on safety glasses and light

If you use plain. sunscreens (cheap sunglass types for example)

it is not certain that there is effective protection against sunlight and other installations ray!

The cornea serves as a kind of filter for the ultraviolet rays, and exposure to light at high can be damaged.

Dark glasses of poor quality only makes things worse. Pupils become dilated behind the dark lens which no protection provider and large quantities harmful rays will pass through the tubes, just when the eye's pupil is fully open.

Many eyeglass manufacturers are not covered by the sun filtering regulations, but can be sold all over the place with a sticker "UV Protection" label.

This endorsement provides no guarantee, however, unless it can make available appropriate documentation (EN 166 and EN 172).
