  1. Vision in theWorkplace date

  2. YOUR NAME HERE • Practice information

  3. Anatomy 101

  4. Nearsightedness • Nearsighted people typically see well up close, but have difficulty seeing far away.

  5. Farsightedness • Farsighted people typically see well far away, but have difficulty seeing up close.

  6. Astigmatism • With Astigmatism the cornea has an oval shaped, like a football • Can occur along with nearsightedness and farsightedness

  7. Presbyopia- The Ageing Eye • Signs and Symptoms • Difficulty seeing clearly for close work • Print seems to have less contrast • Brighter, more direct light required for reading • Reading material must be held further away to see (for some) • Fatigue and eyestrain when reading • The natural lens can no longer accommodate or focus.

  8. Computer Vision Syndrome • Computer vision syndrome (CVS) is a term that describes eye-related problems and the other symptoms caused by prolonged computer use. • These problems are more noticeable with computer tasks than other near work because letters on the screen are formed by tiny dots called pixels, rather than a solid image. 

  9. Tips When Using the Computer • Take frequent breaks • Blink • Avoid sources of glare on screen • Maintain proper distance from screen • Maintain good lighting, brightness & contrast • Ensure your glasses are right for the task • FOLLOW THE 20-20-20 RULE: Every 20 minutes, Take a 20 second break, and Focus on something 20 feet away

  10. Types of Correction • Glasses • Single Vision • Bifocal • Trifocal • Progressive • Contact Lenses • Soft • Rigid Gas Permeable (RGP) • Laser Surgery • PRK • LASIK • Presbyopic?

  11. LASIK Surgery • A special instrument called a keratome is used to gently lift a flap of corneal tissue, then laser is used to reshape the cornea. 

  12. Diseases

  13. Dry Eye Syndrome • One of the most common problems treated by eye physicians. Over 10 million Americans have clinically significant dry eye. • Tears are comprised of three layers.  • Keeps the eye moist, creates a smooth surface for light to pass through the eye, nourishes the front of the eye, and provides protection from injury and infection.

  14. Dry Eye Syndrome • Causes • Age • Environment • Contact Lenses • Medications • Diseases

  15. Dry Eye Syndrome • Symptoms • Burning • Itching • Irritation • Redness • Blurred vision that improves with blinking • Excessive tearing • Increased discomfort after periods of reading, watching TV, or working on a computer

  16. Dry Eye Syndrome • Treatment • Artificial lubricants • Punctal occlusion • Surgery

  17. Cataracts • Clouding of natural lens of eye • UV exposure • Hereditary • Most common cause… age

  18. Cataracts

  19. Age Related Macular Degeneration • A degenerative condition of the macula (the central retina). • Most common cause of vision loss in North America in those 50 or older, and its prevalence increases with age. • Caused by hardening of the arteries that nourish the retina depriving the sensitive retinal tissue of oxygen and nutrients that it needs to function and thrive, resulting in deteriorated central vision.

  20. AMD Prevention • Don’t smoke • Eat your vegetables • Protect your eyes from UV rays

  21. Age Related Macular Degeneration DRY WET

  22. Glaucoma • caused by increased intraocular pressure (IOP) • Left untreated, an elevated IOP causes irreversible damage the optic nerve and retinal fibers resulting in a progressive, permanent loss of vision. • Early detection and treatment can slow, or even halt the progression of the disease. 

  23. Glaucoma

  24. Diabetic Retinopathy • Occurs in later stages of diabetes • Visual symptoms vary from blurred vision (depending on sugar levels), flashing lights, to loss of vision. • Treatment • MAINTAIN BLOOD SUGARS! • Laser/ Victrectomy

  25. Diabetic Retinopathy

  26. Eye Safety • Workplace • Sports • Hobbies

  27. Eye Safety • Assess Your Work Space: • What speed are objects moving? • Is your work surface secure? • Any potential eye hazards? • Check with your health and safety team or supervisor for help.

  28. Eye Safety

  29. Why Get My Eyes Checked?? • To make sure you ensure clear, comfortable vision • To make sure your eyes are healthy • Just because you see well, doesn’t mean your eyes are well!
