Safety Tips | Vision Health Month

Since May is Vision Health Month, we thought for this blog it would be the perfect opportunity to talk a little bit about the importance of vision health!

According to the Canadian National Institute for the Blind, over 700 Canadian workers per day sustain eye injuries on the job, resulting in lost time and/or temporary or permanent vision loss.

That statistic sounds impossible, right? Well, it’s not! Eye injuries on the job can be caused by flying debris like metal pieces or glass, tools, chemicals, harmful radiation or even eye strain due to digital devices. What makes this statistic worse is that 90% of those injuries could have been avoided with the use of proper safety equipment, including safety eyewear.

But Why Are People Not Wearing Safety Glasses?

With an issue like this, you may find yourself thinking, “those people just didn’t put on their safety glasses”, and that’s that. And, to some extent, it is that easy! However, it’s important to take into consideration WHY people aren’t wearing their safety glasses. The Alberta Association of Optometrists found these were amongst the most common when asking people why they don’t wear their safety glasses on the job:

  • “I hate layering glasses over glasses.” If the worker already wears prescription eyewear, putting safety glasses over regular glasses is a hassle. In addition, the worker may not feel he or she can see well enough to do a proper job.
  • “It doesn’t fit right.” If your glasses were ordered online without a fitting, or if they are a generic size, they can be very awkward fitting, and fall off when you most need them.
  • “They look ridiculous.” If workers are self-conscious about wearing safety glasses, they will take them off at the first chance, and could forget to put them back on when necessary (if indeed they know where they left them!).
  • “It’s not necessary, the employer is just doing a CYA” If the bosses don’t wear the safety gear, or exhibit a casual atmosphere toward enforcing it due, employees may think the rules are just for insurance or liability purposes. They may think the dangers are only superficial.
  • “They don’t have sun protection.” If workers are outside without lenses coated with sun protection they may be tempted to wear sunglasses instead of safety glasses. Having any lens in front of the eye can fool workers into thinking they have protection, but there is a huge difference between sun glasses and real fitted safety glasses.

So, with all of those points taken into consideration, our #1 tip for proper vision health in the workplace is access to properly fitted eyewear, and if necessary, prescription safety eyewear dispensed by an Optometrist. Safety eyewear is not a one size fits all solution, you need to be fitted with the correct PPE for your circumstances. If you find yourself wanting to take them off for any reason, fix that reason!

How To Choose the Right Safety Glasses

The Most Important Components of Safety Glasses

Lenses: CSA-certified eye and face protectors must meet the criteria for impact resistance as outlined in the standard. Only devices made of approved materials are permitted.

Markings: The manufacturer or supplier certification mark must be present on all approved safety lenses, frames (front and temple), removable side shields, and other parts of the glasses, goggles, or helmets.

Frames: Safety frames are stronger than street-wear frames and are often heat resistant. They are also designed to prevent lenses from being pushed into the eyes.

What are the pros and cons of the different lenses?

As Defined by the Canadian Centre of Occupational Health and Safety (CCOHS)


  • More impact-resistant than CR39 plastic
  • Available with all surface treatments (coatings)
  • 100% UV filtering
  • Light weight
  • Material is very clear


  • Most impact-resistant of all lens materials
  • Lightweight
  • Can be coated for scratch resistance
  • Most have built-in UV radiation absorption properties

Plastic (CR39)

  • About one-half the weight of glass
  • Resistant to solvents and pitting


  • More impact resistant than CR39 Plastic
  • Less impact resistant than polycarbonate
  • UV radiation absorption properties


  • High-density material resulting in heavy lenses
  • Loses impact resistance if scratched
  • Does not meet impact criteria as set by CSA Z94.3

Proper Fit & Care

  • Ensure your safety eye wear fits properly. Eye wear should cover from the eyebrow to the cheekbone, and across from the nose to the boney area on the outside of the face and eyes. Eye size, bridge size and temple length all vary. Eye wear should be individually assigned and fitted so that gaps between the edges of the device and the face are kept to a minimum.
  • Eye wear should fit over the temples comfortably and over the ears. The frame should be as close to the face as possible and adequately supported by the bridge of the nose.
  • Users should be able to see in all directions without any major obstructions in their field of view.

Eye and face protection devices need maintenance.

  • Clean your devices daily. Follow the manufacturer’s instructions.
  • Avoid rough handling that can scratch lenses. Scratches impair vision and can weaken lenses.
  • Store your devices in a clean, dry place where they cannot fall or be stepped on. Keep them in a case when they are not being worn.
  • Replace scratched, pitted, broken, bent or ill-fitting devices immediately. Damaged devices interfere with vision and do not provide protection.
  • Replace damaged parts only with identical parts from the original manufacturer to ensure the same safety rating.
  • Do not change or modify the protective device.

Eye Protection Classes & How to Choose the Right One

As Defined by the Canadian Centre of Occupational Health and Safety (CCOHS)

Safety at Home and At Work

Vision health hazards aren’t just present at work! It’s important to maintain your vision health all the time, not just when you’re in workplace environments. You may have the perfect eye protection down for work, but if you’re not keeping up with your vision health at home, you could still risk losing one of the senses you rely on the most.

Healthy Vision Checklist:

  • Get an annual eye exam – 75% of vision loss is treatable or preventable if caught early.
  • Wear sunglasses – Sunglasses protect against serious eye conditions caused by UV exposure.
  • Don’t smoke – Smoking increases the likelihood of cataracts, optic nerve damage, macular degeneration. Smokers are also 4x more likely to go blind in old age.
  • Avoid common sources of eye injury – Common sources of eye injury in the home include, home renovations, makeup applicators, fingernails, household cleaning products, poorly fit contact lenses and misused contact lenses.
  • Know your history – Many eye diseases are hereditary, talk to family members about their eye health history.
  • Take eye infections seriously – Symptoms can include redness, pain, discharge, itching, blurry vision, light sensitivity and swelling. If you suspect an eye infection, visit your Doctor of Optometry immediately. Delaying treatment could lead to vision loss.
  • Have an eye doctor who knows you – Having a Doctor of Optometry that knows you and the history of your eyes helps ensure you get the right care at the right time.

Why wear safety glasses? | Training Tuesday

Why wear safety glasses?

Why wear safety glasses? Luckily, it’s Training Tuesday at Hercules SLR, where we bring you training tips for rigging, securing, lifting, safety and more each week. 

This week, the focus is on eye safety and why you should wear safety glasses—Even when it seems trivial. 

First of all, why wear safety glasses? Well, even with all we know about the importance of eye safety and the availability of eye glasses, approximately 700 eye injuries happen to Canadian workers each day, and each year about 720,000 eye injuries occur at work and home—According to the Workplace Safety & Prevention Services, nearly 90% of these injuries are preventable. One in four people who sustain eye injuries must take time off school or work. 

So, why don’t workers wear safety glasses? There are a few reasons. For every 5 workers injured, 3 were not wearing eye protection. 

Common excuses for not wearing eye protection include: 

  • Don’t fit comfortably over their prescription glasses 
  • They don’t fit well, slip, are tight, etc. 
  • Think the rule doesn’t really apply to them or is unnecessary 

Yes, these issues can make PPE uncomfortable, but are easily remedied to give you comfort and safety. Low-cost, scratch-resistant prescription safety glasses or lens-covers are available. Yes, it’s important to wear a pair of comfortable glasses, and safety glasses are available in a variety of styles and fits so everyone can find a style that suits their needs. As far as being unnecessary, if there’s a rule in place that states you should wear safety glasses—You should.

Even if you’re just doing what seems like ‘a quick job’, accidents and injuries also happen quickly. 

So, why wear safety glasses?

Well, safety glasses are a defense against hazards at work that could injure your eyes (or other body parts, for that matter). 

safety glasses statistics























Some of these hazards include: 

  • Dust, dirt and other debris 
  • Chemicals, like irritants and corrosives 
  • UV radiation from electrical or welding work 
  • Flying particles from cutting, drilling, digging, etc. 
  • Tree branches or other obstacles faced when working at heights or in natural environments 

Safety glasses are a great step to take to reduce these hazards, and eliminate eye injuries. In addition to safety glasses, employers and workers should take these additional steps to reduce, or eliminate hazards and prevent injury—To reduce eye-related hazards in general: 

  • Use protective screens/side shields with your safety glasses as needed to prevent particles from falling into eyes. 
  • Try to enclose sources of irritants (Gases, fumes, dusts, etc.) 
  • Isolate hazards whenever possible (EX. Keep equipment, like table saws, away from high-traffic areas or from workers who don’t use them). 
  • Keep work areas well-lighted to reduce glare from ignitions and other light sources 

Types of Safety Glasses

Good protective eyewear should be light, comfortable, allow a clear line of vision, block radiation if/when possible, be adaptable to working conditions, have good ventilation and be scratch-resistant. 

Certification or the manufacturer mark should be available on all safety glass lenses, frames, side shields and any other parts of the glasses. The frames should be designed to prevent lenses from dislodging from frames and into eyes, have more strength than typical optical glasses and are usually heat-resistant. 

There are 6 classes of eye (and face) protection. These are: 

CLASS 1: Safety glasses

CLASS 2: Safety goggles

CLASS 3: Welding helmets 

CLASS 4: Welding hand shields 

CLASS 5: Hoods 

CLASS 6: Face shields 

According to the Canadian Standards Association (CSA), safety glasses should be impact-resistant. They outline three different, common types of lens materials—But not all should be used. 

The three different and common types of lens materials are: 


  • Strongest for impact-resistance
  • Can have scratch-resistant coating and UV protection


  • Lightweight (Weighs about 1/2 of what glass does)
  • Resistant to solvents & pitting 


  • Highly-dense material
  • Loses impact-resistance when scratched, and are prone to scratching 
  • Glass lenses do not meet the CSA impact criteria


  • More impact-resistant than CR39 plastic 
  • Less impact-resistant than polycarbonate 
  • Has properties to help absorb UV rays 


  • More impact-resistant than CR39 plastic 
  • Less impact-resistant than polycarbonate 
  • Has properties to help absorb UV rays
