Goggles

Goggles to protect the eyes from harmful influences such as strong light, chemicals, dust, splinters or weather. You will find, therefore, primarily in labor and in the sporting environment use. Goggles from both areas are basically constructed as optical glasses. The most common form are the one or two- disc glasses as the conventional optical glasses are fixed by ironing over the ears. With the goggles, the eyes are protected by a peripheral seal. The sealing seat ensures an adjustable headband. So-called clip- be additionally attached to an optical glasses or a single- or twin lens.

Working environment

The protection of the eyes during work is important. External influences can irreparably damage the eyesight often. This can be performed from one moment to another (eg from flying particles ) and insidious (eg, by a lack of protection from UV radiation). Therefore, all goggles must the special requirements of the European standard EN 166 and be certified in accordance with this by an independent test institute. Often it comes with goggles on additional options. In the BGR 192 ( trade association rules for safety and health at work) it should be noted that additional influences must be considered. A classic goggles can provide in meeting the requirements of the DIN EN 166 up to 100% UV protection. Accordingly damaged glasses or parts must be replaced (see 1000 Hour Glass and Automatic welding filters ).

Goggles are used for example in the work environment of natural stone, wood and metal processing plants, chemical laboratories - there also called chemist glasses - as well as medical practices, in which laser treatments are performed. Goggles for last named work environment mostly consist entirely of plastic and have only where it counts on the protection against excessive light or radiation over some heavily tinted glasses. For carriers of optical glasses exist larger goggles that can be worn on such a spectacle, otherwise comply with goggles in the size of conventional eyeglasses. When electrical and autogenous welding, the eyes of the person performing must be protected by goggles, as there is serious burns of the conjunctiva ( the so-called verblitzung ) can come of the eye otherwise.

Goggles for professional use must have a fixed, predetermined by the EU labeling (cf., EN 166 and EWG/89/686 ). If the sight glass and the frame are made of different materials, then both must be marked independently.

• Number of the current standard: 166
• Filter protection level from 1.1 to 16
• Identification mark of the manufacturer
• Optical Class: 1, 2, or 3
• CE mark and product name ( if not in package )

Military environment

In the military environment is referred to as tactical goggles. Here stands beside protection from light, dust and other environmental influences particularly the protection against splinters and projectiles in the foreground. Different protection classes, such as the common in the United States ANSI standard or the NATO standard STANAG, define projectile sizes and velocities, which can withstand the specially hardened plastic glasses. There are various types of tactical goggles; over sunglasses with inserts and ironing up to close to the face final models, which are fastened to the head with a circumferential stretch straps. In addition, the compatibility is important with the helmet used within the military unit.

Sport and Leisure

Protect the goggles from the elements, are used in many outdoor sports. They are individually tailored to the particular sport.

• Ski and snow goggles rest on the face and protect against umherfliegendem snow, and harmful UV rays.
• Cycling Glasses are about to face, have a relatively large area, so that the field is not restricted, and protect the eye from excessive wind and the consequent drying out and from flying debris such as flies. The holders of such glasses are traffic needs. So there is no thick side edges.
• The glasses of swimming goggles enclose the eyes usually solitary and avoid contact with the water. Thus, no chlorine or floating in the water can penetrate foreign body in the eye. In addition, they improve vision under water.

Sports goggles are strong influences of fashion and have even set fashion trends. To allow spectacle wearers wearing such glasses, many manufacturers offer special prescription lenses that are most often placed behind the actual lens.

Prescription safety

Prescription safety are a combination of protective and corrective eyewear. They combine the compensation of an optical refractive error with the protection of the eye from mechanical, chemical or optical influences. With appropriate risk potential in everyday work the Occupational Safety Regulations ( BGR) writes 192 their use in practice binding.

Field of application

In our everyday work, there are many dangers to the eyes - of chemicals to splinters and chips. Thus, the eyes are not hurt, are also available for employees who have a refractive error to take adequate security measures. BGR 192 states: " Commercial Eyeglasses have no protective effect. Therefore, the entrepreneur must also ametropic insured provide suitable eye protection available " prescription safety here provide a reliable way for eye protection with simultaneous correction of refractive errors: ". [ It ] is the use of prescription safety is recommended, as they combine the protective and corrective action. Prescription safety experience has shown are easily carried by the affected insured and also regularly maintained better. "

Function

According to BGR 192 are prescription safety " goggles - usually frame glasses -. Equipped with safety viewing glasses with optically corrective action " you are on the refractive error ( for example, short - or farsightedness ) of the respective carrier adapted while offering protection against the various hazards in the work environment.

The glasses a prescription safety are such that they ensure a much higher breaking strength than standard lenses. At the same time the frame on the requirements of each job is tailored - for example, with particularly large viewing areas or guards against splashes on the sides. In addition to the pure idea of ​​security comfort also is taken into account: only when the socket well and is comfortable, neither disturbs nor suppressed, the employee bears the glasses - and only then access control policies and the correction of vision.

Both the adaptation to the individual optical parameters of the wearer, as well as in the search for the correct version helps the optician. He must adjust the prescription safety not only to the personal needs of the employees, but also to the conditions in everyday work, so to the potential dangers. In addition, the prescription safety must be certified according to DIN EN 166. Only those who comply with these standards and marks the optical glasses accordingly, also " Supplier of corrective goggles " may call.

Interim solutions

There are also temporary devices that protect poor eyesight at work - but this is no long -term solutions are: " For short-term work for a few minutes, for example, basket, over glasses or visors may be worn. Combinations with basket or over though glasses tend to fog up, it can result in additional hazards and are therefore often rejected. Moreover, such combinations often cause annoying double images or reflections. "

Reimbursement

The cost of prescription safety borne by the employer. This also BGR 192: " According to § 2 of the PSA - user order the entrepreneur must the insured provide eye and face protection available if the hazard can not be otherwise prevented or impaired. " The cost of prescription safety are a long-term investment, return: ". 's acquisition of eye protection is expensive, but it is equivalent in almost all cases by the significantly longer duration of use of " addition, the operation can benefit that employees protected and can work with full sight, as so the failure rate and the associated costs are reduced, while the quality of work is better. This has also been confirmed in studies.
