This resource will give an overview of eye safety and protection in the workplace. It will cover everything, from the range of colors, to the types of lenses.

You can protect yourself by using safety glasses that meet the ANSI standards.

ANSI / ISEA Z87.2015. The American National Standard for Occupational and Educational Personal Eye and Face Protective Devices, updated their standard eye and face protection regulations. This regulation first came into play in 1968. Since this year, the standards have been reviewed and revised five times. The 2010 revision increase safety requirements for working with hazard based structures. The revision in 2015 adds to protect people against product performance and was able to meet global standards dealing with hazard based structures.

The ANSI/ ISEA 2015 revision breaks the hazards down into categories. This includes heat, chemical, dust, and optical radiation. Each hazard has its own specific evaluation process, and there are specific protection equipment that should be used for each hazard. Protections are divided into minimum impact or high impact. A manufacture must add the type of lenses they have put into the product such as ultraviolet filter, welding, visible light fillers, or even infrared fillers. They must also include what the lens is going to protect a person against, including dust, splashes, and the type of lens that is being used, as well as where they were made.

Challenges Workers Face When Using Protective Eyewear

Coating of the Lens

The coating of the lens can be prolonged by using separate coatings, or coating that can be added on glasses to enhance their current function.

Anti fog lenses will help reduce fog when going from cold to warm temperatures. It will also work with areas where the temperature transitions quickly and areas that are high in humidity.

Lenses that are scratch resistant will protect the eye, as well as the lens, when an individual works in an environment where scratches may be possible.

Anti static lens will reduce the attraction of dust to the lens.

Hard coating lenses are bonded to make the lens last for a longer period of time.

Anti UV coated lens will absorb over 99 percent of ultraviolet radiation and keep it from reaching the eye.

Colored Lens

The color of the lens can determine a specific task that it has been designed for. It will also allow a person to know what environment the particular lens is safe to use in. When selecting a lens, pick a pair based on color opposites. Blue is the opposite of yellow, and the colors red and greens are also opposites. A red lens is able to absorb the green lights, and the yellow lens are able to absorb any blue lights a person may be exposed to. The same is true when switches around.

Clear - This lens in particular is good for indoor conditions, and can be used where impact protection is going to be needed.

Gray - This is for people that work outdoors, and a glare can cause vision troubles.

Indoor and Outdoor - A clear lens with a mirror coating will function the same way that a gray lens does, and allows more light to be able to get through to the lens. These lenses can be used in outdoor or indoor settings. It will also reduce the amount of glare produced by artificial lights.

Gold, Blue, and Silver Mirrors - These lenses can be used in outdoor settings where glare from the sun can become an issue. The mirror coating is able to reflect the lens and reduce the amount of light that is able to reach the eye.

Brown/ Espresso - These lenses are good for outdoor use where the sun can cause problems. These lenses are even able to meet color traffic signal recognition requirements for safety.

Vermillion - These lenses are able to enhance the contrast levels and reduce all the color equally so that a person will be able to clearly see ach color. There are good for indoor inspections.

Amber - This color is able to block out the blue lights on the visible light spectrum. This will create contract when used with low lights as well.

Filter Shades - This will protect a person from radiation that is related to filler lens density. Always look for the darkest shade for the most protection.

Are Safety Reading Glasses Needed?

Why use Safety Reading Glasses?

Based on information from the 2010 United State Census, there are over 81 million people in this country that are between the ages of 45 and 64 years old. Many of these people need reading glasses to see clearly. They may also need safety glasses in addition to these reading glasses.

Save the Company Money

Over 75 million pairs of non prescription safety glasses are sold each year. Ten percent of those require additional safety features. This can run around $150 for each pair. In order to save money, a company should therefore offer their employee safety reading glasses.

Look at the Savings

The average cost of reading glasses is around $20 a pair. If the employee uses safety reading glasses, then they can save the company $130 per year. If there are 500 workers who all have this same requirement, then this could be up to $6,500 in savings.

Look for Diopter Strength

Be sure to check out the diopter chart. This can be printed out as well as the instructions.

Definitions for Eye and Face Protection

Accessory - something that is used to complete a device that does not have an effect on the performance.

Aftermarket component - a component that is not produced by the manufacture and is not supplied with the lens

Cover Lens - lens used to protect the surface of another lens. It is not used as a safety device

Faceshield - a shield worn on the face for protection. It will reduce hazards as indicated by the markings that can be found on the shield.

Full Facepiece respirator - this respirator fits tightly and is able to cover the nose, mouth, and eyes.

Goggle - this fits around the face and the eyes. It will protect from specific hazards

Hand shield - a helmet for welding

Impact Resistance - eyewear that will protect the eyes and meets all ANSI regulations.

Infrared radiation - wavelengths that range from 780 to 2000 nm.

Loose Fitting respirator - this will cover part of the face or the head and neck as well as some of the shoulders.

Luminous transmittance - this will allow light from 380 to 780 nm to pass through

Magnifier - a non prescription lens has refractive power. This can be inserted into welding devices.

Nanometer - nm, this is equal to one billionth of a meter

Optical radiation - wavelengths that range from 200 to 2000 nm.

Protector - device that meets the requirements listed in Section 5 of the ANSI ISEA regulations

Reader - a non prescription spectacle that uses refractive power in a portion of the lens

Side Shield - device that provides lateral protection

Spectacle - will shield the eyes from specific hazards

Ultraviolet radiation - wavelengths from 200 to 380 nm

Welding Face Shield - shield that will protect the face when a person is involved in welding

Welding goggles - will provide protection when welding

Welding helmet - will protect the eyes from radiation and welding splatter

Welding respirator - will provide protection from radiation during welding

These are just some of the things that a person should keep in mind when purchasing or using safety glasses. Selecting the right form of safety goggles and glasses can help provide the protection that a person needs. A company has to be sure that they’re in compliance with all safety regulations, and this guide will help them keep employees safe!
