Have Your Eyes
Checked
Why Have Your Eyes Checked?
• Your Eyes…What could be more important?• “Arms to short”, “need new glasses”• 80% of our day involves our eyes and vision• 1 in 7 people who think their eyes are fine actually have
the start of significant eye disease • 5.5 million have major eye disease
• Accurate determination of spectacle and contact lens prescriptions• Detection of refractive, visual and eye muscle conditions• Detection and prevention of eye disease• Detection and prevention of complications secondary to systemic disease
Vision Loss (Impairment)
• 50,000 Canadians every year• People with severe vision loss or blindness:
o By age 40 1 in 28 people
o By age 60 it is 1 in 9 people
o By age 70 it is 1 in 4 people
• 75% of vision loss can be PREVENTED!• 90% of workplace injuries can be PREVENTED!
Common Causes of Vision Loss
and Impairment
Common Causes of Vision Loss1. Eye Diseases and Conditions
• Glaucoma• Macular degeneration• Diabetic Retinopathy• Retinal Disease/Conditions • Cataract
2. Congenital or Childhood Blindness3. Trauma, Injury, Accidents
Workplace Statistics
Men account for 68% of injuries
Women account for 32% of
injuries
Workers under 24 years
account for 13%
Workers over 55 years account
for 21%
Average age for a eye accident
42 years
WorkSafeBC Statistics
Three out of every five workers injured were not wearing eye protection a the
time of the accident
70% of eye injuries result from flying or falling objects or sparks striking the eye
Contact with chemicals caused 20% of the eye injuries reported in the work
place
66% of all eye injuries occur outside the workplace
It is estimated that nearly 60% of objects striking the eye were smaller than a pin
head
40% of all objects striking the eye were from around the frame front
90% of all workplace eye injuries are preventable by wearing the
correct fitting eyewear
Having a safety eyewear program mitigates potential workplace injuries that
can result in significant costs in both human and financial resources
Most Common Eye Injuries• Blunt Injuries
o External
o Penetrating
• Foreign Bodies, Cuts & Abrasionso Sterile
o Organic
• Chemicalo Gas
o Liquid
o Solid

Why don’t employee’s wear safety glasses?
• Too Expensive• Company policies only
suggest eyewear• Self employed /
contractor• Employee don’t find it
necessary to wear eye protection
• Eyewear doesn’t fit• Eyewear uncomfortable• They look ridiculous
How can we help stop these statistics
