2. Healthy Vision in the
Workplace
• Eye safety statistics
• Types of eye hazards
• Types of eye protection
3. Eye Safety Statistics
• According to the National Institute for
Occupational Safety and Health (NIOSH),
every day nearly 2,000 U.S. workers sustain
job-related, vision threatening eye injuries
that require medical attention.
4. Eye Safety Statistics
• Approximately 60 percent of workers with eye
injuries in a Bureau of Labor Statistics (BLS)
study were not wearing the proper
protective eyewear at the time of their injury.
6. Foreign Bodies in the Eye
• The BLS study reported that 94 percent of the
eye injuries which occurred while a worker
was wearing protection were caused by
sparks, debris or chemicals striking the eye
from around or under the protective shield.
7. Foreign Bodies in the Eye
• Nearly 70 percent of the eye injuries reported
in the BLS study came from flying debris,
sparks and small objects striking the eye.
• Most of the objects were smaller than a pin
head.
8. Protective Eyewear
• Protective eyewear needs to be properly fitted
to be effective.
• Training employees on the proper use of
protective eyewear can reduce workplace eye
injuries.
10. Safety Glasses
• Safety glasses may look like normal
eyewear, however they are designed to
provide much more protection.
11. Safety Glasses
• Lenses and frames are much stronger
than regular glasses and are
constructed to prevent the lenses from
shattering or being pushed toward the
eyes.
12. Safety Glasses
• Those working in an area that have the
danger of small particles, flying objects
or dust should have the wraparound-
style of safety glasses or use side
shields.
13. Goggles
• Goggles with polycarbonate or Trivex®
lenses are highly impact resistant and provide
protection from dust and chemical splashes.
14. Goggles
• They cover a large area around the
eyes and protect against hazards from
any direction.
• Goggles can be worn over prescription
glasses and contact lenses.
15. Face Shields & Helmets
• These secondary protectors do not
provide adequate protection alone and
should always be used with primary
eye protection devices such as safety
glasses and goggles.
16. Eye Safety in the
Workplace
• Employers are required by the Occupational
Safety and Health Administration (OSHA) to
provide face and eye protection to workers at
risk for job-related
eye injuries.
17. • Eye strain is the most common eye
problem for those who use
computers frequently at work.
Eye Strain
18. Eye Strain
• Computer use requires specific
vision skills that require additional
demands on the visual system and
contribute to eye and vision
discomfort.
20. Eye Strain
• Computer Vision Syndrome (CVS) is
the complex of eye vision problems
related to near work that are
experienced during or related to
computer use.
21. • The use of hand-held devices such as
‘smart phones’ and PDA’s can also
cause eye strain.
Eye Strain & Hand-held
Devices
22. Prolonged usage of these devices may lead
to a host of issues:
• Eyestrain
• Headaches
• Burning or tired eyes
• Loss of focus
• Blurred or double vision
• Neck & shoulder pain
Eye Strain & Hand-held
Devices
23. Ease the Strain
• Give it a rest
• Size up
• Sharpen up
• Reduce glare
26. Ultra-Violet Radiation
• Non-solar sources of UV radiation
include:
• Arc welding
• Curing of paints and inks
• Disinfection of equipment in hospitals and
laboratories
27. Ultra-Violet Protection
• Wear protective eyewear any time the eyes are
exposed to UV rays.
• Choose quality sunglasses that block out
99 -100 percent of UV radiation and screen out 75 –
90 percent of visible light.
• Clear lenses can be treated with a coating to protect
eyes from UV.
28. New occupational tasks can
result in new vision needs.
• A change in one’s job tasks may require
different focusing abilities. This is especially
true for workers over 40 years old, whose
eyes are susceptible to presbyopia, a natural
loss of focusing ability.
29. Eye Safety at Home & Play
• Many people are conditioned to wear protective
eyewear at work, but forget to wear it at home and
during recreational activities such as:
• Yard work
• Hammering
• Wood working
• Grinding
• Playing sports – baseball, hockey, golf
30. In Conclusion…
Eye safety in the workplace is proven to
prevent loss of vision.
To further ensure healthy vision be sure
contact your optometrist to schedule a
comprehensive eye exam.
Thank you for having me speak to your group.
March is Save Your Vision Month. This is an annual campaign that helps to raise awareness of the importance of regular, comprehensive eye exams and offers suggestions on how to maintain good eye health.
Today, I will be speaking on Healthy Vision in the Workplace. It doesn’t matter if you work in an industrial setting or an office setting – good vision, healthy eyes and proper eye safety are important.
Some of the topics we will cover today include:
some important statistics on eye safety
go over the different types of potential eye hazards that you may come in contact with while on the job
and the different types of protection available
Please feel free to ask questions as we go through the information.
There are a variety of hazards, accidents and activities that lead to eye injuries including chemical, grease or oil splashes, burns from steam, flying chips of wood or metal, eye strain and ultra-violet or infrared radiation.
Objects in the eye often cause minor irritations but there is a risk of more severe damage if the eye receives cuts or scrapes.
There is a solution to prevention and avoiding eye injuries. Experts agree that 90 percent of all eye injuries in the workplace could be prevented by wearing properly designed and fitted protective eyewear.
A large majority of employers provide protective eye equipment to employees. However, a much smaller portion of employers provide training for the proper use of eyewear.
Employers may choose to implement a Vision Conservation Program to administer all aspects of eye safety. Vision conservation programs are most successful when occupational health, safety officers, industrial hygiene and optometric professionals are included.
When it comes to protective eyewear, no one size or style fits everyone. Just as you need to be properly fitted for prescription eyeglass or contact lenses, protective eyewear also needs to be fitted and designed to match the hazards.
What type of protection best suits the task or tasks can be determined through a hazard assessment for each activity.
Safety glasses shield the eyes from front and side impact. The lenses and frames used for safety glasses are much stronger than regular eyeglasses and are constructed to prevent the lenses from shattering or being pushed toward the eyes.
Safety lenses are available in glass, plastic, polycarbonate and Trivex® materials.
All four types must meet or exceed the minimum requirements for protecting your eyes – however, polycarbonate and Trivex® lenses provide the highest level of protection from impact.
Safety glasses must meet the rigid standards of the American National Standards Institute. Look for the ANSI Z87.1 mark on the lens or frame.
Similar to safety glasses – safety goggles with polycarbonate or Trivex® lenses are highly impact resistant. Safety goggles provide protection from dust and chemical splashes.
Safety goggles differ from safety glasses in that goggles proved complete eye coverage with a sealed rim around the eyes.
Face shields and helmets are not protective eyewear and must be worn with safety glasses or goggles.
Full face shields are used to protect workers exposed to chemicals, heat or blood borne pathogens.
Wearing safety glasses or goggles under face shields also provides protection when the shield is lifted.
Helmets are used when welding or working with molten materials.
According to the American Optometric Association’s 2009 American Eye-Q® survey, more than four out of five Americans spend time in front of their computer or hand-held devices.
Eye strain is the most common eye problem for those who use computers frequently at work.
Any computer use requires specific vision skills that place extra demands on the visual system and contribute to eye and vision discomfort.
Such visual skills include:
Ocular motility – which is the ability of the eyes to move in various positions
Accommodation – the ability of the eyes to focus clearly at various distances
Vergence – the ability to move the eyes in or out
The American Optometric Association defines Computer Vision Syndrome or CVS as: the complex of eye vision problems related to near work that are experienced during or related to computer use.
CVS is characterized by visual symptoms which result from interaction with a computer display or its environment.
In most cases, the symptoms occur because the visual demands of the task or tasks are greater than the visual abilities of the individual.
For those parents in the room, I would like to note that CVS is not restricted to adults. Children are also spending more and more time in front of computers and using hand-held devices. They can experience CVS too!
Until recently, most Americans dealt with eye strain only as it related to their computer screens. While smart phones, PDAs and other hand-held gadgets may be great time-saving devices, the users are experiencing additional vision and other problems.
Additionally, the Eye-Q survey revealed that 42 percent spent three or more hours a day looking at a computer or hand-held device.
Here are some ways to ease the eye strain that results from using the computer and hand-held devices.
Give it a rest – Whether you are working at a computer or from your PDA - remember the 20-20-20 rule. At least every 20 minutes, take a 20-second break and view something 20 feet away.
Size up – The smaller screens on hand-held devices usually have tiny type that forces squinting and bringing the screen closer to the eyes taxes the visual system. Try increasing the font size so the device can be held at a more comfortable distance.
Sharpen up – Most hand-held devices allow users to adjust both the screen resolution and contrast. Avoid using in bright light, which reduces contrast.
Also, the brightness of a computer monitor should be adjusted based on the brightness of the surrounding area.
Reduce glare – When possible, try to make sure lighting is not directly behind or in front of the head. Reducing glare eases reading and may make a bigger difference than increasing the type size.
Look down – Just as on a computer screen, it's easier on the eyes to focus on reading material that is below eye level. Keep your hand-held device positioned so that you are viewing it below eye level.
Think blink – People tend to blink less frequently when viewing a computer screen (and hand-held devices). Blinking is a natural way to help moisten the eyes and prevents dryness and irritation.
Diet and nutrition – Numerous studies have shown how diet and supplements can improve vision. The Omega 3’s in flaxseed and fish oil supplements improve long-term lubrication for the eyes.
Most of you are well aware of the harm the sun’s ultra-violet or UV radiation can do to your skin. However, exposure to UV radiation can also harm the eyes and affect vision.
The longer the eyes are exposed to UV radiation, the greater the risk of developing later in life conditions such as cataracts or macular degeneration.
While those who work outdoors are most likely to be affected by long-term exposure to UV radiation, others may also be exposed to non-solar sources.
Since it is unclear how much exposure to UV radiation will cause damage – it is recommended that you wear quality sunglasses that offer UV protection whenever you spend time outdoors – that includes cloudy days and even in the winter.
When selecting sunglasses choose those that:
block our 99-100 percent of UV radiation
screen out 75-90 percent of visible light
Are perfectly matched in color and are free of distortion and imperfection
Have gray lenses for proper color recognition
Again – the lenses in sunglasses should be made from polycarbonate or Trivex® material if you participate in potentially eye hazardous work.
It is also important to note that a change in one’s job tasks may require different focusing abilities. Those workers who recently received new job duties may experience some changes in their vision. This is especially true for those over 40 years whose eye are susceptible to presbyopia which is the natural loss of focusing ability.
I have been talking about eye safety in the workplace and it is, indeed, a very important topic. However, I would like to take a moment to remind you that eye safety should also be practiced at home and during recreational activities. Protective eyewear should be worn while doing the following activities:
Yard work
Home improvement projects such as – woodworking, hammering and grinding
And when playing sports – for example – baseball, hockey and golf.
