Visualize the Future: Choosing the Right Safety Eyewear en


From features to lens color, the options are endless

Personal protective equipment (PPE) is crucial for reducing the risk of worker injury. Wearing PPE is not enough. You need to ensure that workers are wearing the right PPE for the specific job application and environment.  
According to NIOSH, 2,000 workers sustain eye injuries at work every day. About one-third of these injuries require medical attention at a hospital. The most common eye injuries are striking/scraping, penetration and chemical/thermal burns. A small minority of workers contract eye diseases such as the avian flu or hepatitis B. Ninety percent of workers could lessen or avoid injury by wearing eye protection according to ISHN. 

Safety Eyewear Types 
The reason the term safety eyewear is often used instead of just safety glasses is that eye protection comes in more forms than just the standard frameless lens. Each variation has its own benefit. 
Full frame glasses feature lenses that are surrounded and held in place by a sturdy frame, making them perfect for a multitude of job applications or for leading an active lifestyle. They also tend to provide a closer fit than half frame or frameless options.  
Half frame glasses blend the breathability of a frameless design with the durability provided by a full frame. Many half frame options come with an adjustable nosepiece feature allowing them to function and fit much like regular glasses. They are ideal for any application where both durability and an unobstructed line of vision are equally important. 

Frameless  eyewear perfectly couple simplicity and style allowing them to work in applications and environments where a full field of vision is ideal, if not essential. Because they are lightweight and provide the wearer with an unobstructed view, they are excellent choices for those required to wear eye protection for extended periods of time.5
Goggles provide protection against a variety of different potential hazards, including things like chemical splash, flying particles, wind, sun glare and dust. No matter what unique protection your application or environment requires, with features like thermo and anti-fog lenses, open and close ventilation systems, and removable face shields, there are goggles to meet your needs.
Over the spectacle eyewear is intended for those who require additional protection over their prescription glasses. They are designed with channels built in to accommodate another pair of temples, meaning you never have to remove your prescription glasses to comfortably achieve the protection you need.
Readers are designed to better assist those who require both safety glasses and prescription lenses. Readers come in two forms, glasses and inserts, with anywhere from a 1.0+ to a 3.0+ magnification. Many options will also accommodate a personal prescription from an optometrist. 
Sealed and foam padded eyewear are often ideal options for dusty or windy work environments. Some sealed and foam padded eyewear products also come with features like sealed rubber gaskets, interchangeable temples, and goggle straps, which make them easily customizable.

All these types of eye protection have their own pros and cons depending on the job to be done.  

Eye Protection Features 
There are several features that cross over the various types of safety eyewear that have an impact on their function and practical use. Worker preference can also play a role in which eyewear features matter.  
The most important feature is safety standards. In the US and other countries, PPE is required to meet certain safety standards to be used in some applications and on certain jobsites. In the US, that standard is ANSI. ANSI reevaluates its standards every five years and many manufacturers retest their products against the new standard at independent labs. Canada uses the CAN/CSA standard and the EU/UK use the CE standard.  

Lens Options 
Lens color and treatments are the second most important feature to consider when choosing eye protection. Certain lens colors or treatments can make doing a job safer or easier. Each lens color lets in a specific amount of visible light which protects against harmful UV rays.
Color is not the only variation that can happen with lenses. They can also feature different treatments-scratch resistance, anti-glare, and anti-fog coatings. 
For specialized needs, there are also safety glasses available with polarized and photochromatic lenses. Polarized lenses help reduce glare, increase clarity and enhance contrast which is crucial for safety in settings around water. Photochromatic lenses are especially useful for workers who frequently go from indoor to outdoor areas as they darken when exposed to UV light.  
Most safety glass lenses are made from polycarbonate. Polycarbonate lenses are up to 10 times more impact resistant than plastic or glass lenses and provide 99 percent protection from the sun’s harmful UV rays. In addition, they are lightweight and include a scratch resistant coating for longer longevity of the eyewear.  

Comfort Features 
One of the main reasons workers remove their eyewear is comfort. Workers need eyewear that can be worn all day without complaints. Common features to help alleviate these objections include adjustable nosepieces, co-injected temples, rubber tips and nosepieces, ratcheting temples and foam padding.  
Questions to Ask When Choosing Safety Eyewear 
There are many variables, and some of them come down to user preference. No matter what job a worker is doing, asking these questions can help you choose the right safety eyewear.  

  • Is eyewear required to meet certain standards? 
  • Does eyewear need to protect against dust or splash? 
  • Is a specific lens color warranted or advised against? 
  • Is fogging a potential issue?  
  • How long will the eyewear be worn? 
  • Would magnification be useful? 
  • Does the worker already wear glasses? 
  • Will these be used for welding or around flash? 
  • What eyewear does the worker prefer? 
  • Choosing proper eye protection is not a science as much as it is an art.
