    1. Sports Vision

    2. Sports Vision Performance in sports can be enhanced by good vision

    3. Correction of refractive errors Eye protection Visual training The role of optometrists in sports vision

    4. Refractive errors • Short-sightedness, long-sightedness, or astigmatism • Correctable with glasses or contact lenses

    5. Normal focus

    6. Short sightedness (Myopia) Distance vision blurry, near vision usually ok Short sighted focus Short sighted correction

    7. Long sightedness (Hyperopia) Difficulty seeing clearly and comfortably up close Long sighted focus Long sighted correction

    8. The eye is shaped more like a football than a basketball Focusing error that causes blur in one direction Astigmatism

    9. Binocular vision • Equal vision in both eyes • Provides stereoscopic or 3D vision • Good to have a ‘spare’ eye

    10. Important for good hand-eye coordination, eg putting a ball in golf hitting a ball over a net in tennis kicking a ball through a goal Requires two eyes seeing equally Can be trained Depth perception

    11. Diagram of the eye

    12. Eye trauma • Can cause bleeding in the white of the eye • Usually resolves after 1-2 weeks • Important to check with an eye care professional

    13. Retinal damage Normal retina Damaged retina

    14. Conditions caused by extended exposure to UV rays 1. Pterygium

    15. Conditions caused by extended exposure to UV rays 3. Age-related macular degeneration 2. Cataract

    16. Eye protection • Especially in squash, indoor cricket • Lenses need to be plastic, not glass • Damage can cause permanent blindness

    17. Swimming goggles • Protect the cornea from strong chlorine • Can be worn with contact lenses, but only if they don’t leak

    18. Sunglasses • Prevent absorption of UV light into the eye • Good for outdoor sports such as cricket and tennis • Should comply to Australian standards Wrap around frame is good protection

    19. Squash goggles • Polycarbonate lenses are tough and light • Squash ball is the same size as eye socket, and can enter at high speeds • All junior players are required to wear eye protection

    20. Contact lenses • Good for contact sports such as football or rugby, where glasses frames could cause damage if knocked • Also good in situations when glasses can fog up

    21. Works with different types of eye movements turning eyes in and out smooth, following movements quick, jerky movements See an optometrist with an interest in sports vision training Visual training

    22. Provide a comprehensive visual examination Detect and diagnose eye health problems Prescribe and supply glasses and contact lenses when required Diagnose and treat eye coordination and focussing problems Optometrists
