The role of optometrists in sports vision
• Correction of refractive errors
• Eye protection
• Visual training
![Page 4: Sports Vision. Performance in sports can be enhanced by good vision](https://reader036.vdocuments.us/reader036/viewer/2022062314/56649eb55503460f94bbd73f/html5/thumbnails/4.jpg)
Refractive errors
• Short-
sightedness,
long-sightedness,
or astigmatism
• Correctable with
glasses or
contact lenses

Normal focus
![Page 6: Sports Vision. Performance in sports can be enhanced by good vision](https://reader036.vdocuments.us/reader036/viewer/2022062314/56649eb55503460f94bbd73f/html5/thumbnails/6.jpg)
Short sightedness (Myopia)
Distance vision blurry, near vision usually ok
Short sighted focus Short sighted correction
![Page 7: Sports Vision. Performance in sports can be enhanced by good vision](https://reader036.vdocuments.us/reader036/viewer/2022062314/56649eb55503460f94bbd73f/html5/thumbnails/7.jpg)
Long sightedness (Hyperopia)Difficulty seeing clearly and comfortably up close
Long sighted focus Long sighted correction
![Page 8: Sports Vision. Performance in sports can be enhanced by good vision](https://reader036.vdocuments.us/reader036/viewer/2022062314/56649eb55503460f94bbd73f/html5/thumbnails/8.jpg)
Astigmatism
• The eye is shaped more like a football
than a basketball
• Focusing error that causes blur in one
direction
![Page 9: Sports Vision. Performance in sports can be enhanced by good vision](https://reader036.vdocuments.us/reader036/viewer/2022062314/56649eb55503460f94bbd73f/html5/thumbnails/9.jpg)
Binocular vision• Equal vision in both
eyes
• Provides stereoscopic
or 3D vision
• Good to have a
‘spare’ eye
![Page 10: Sports Vision. Performance in sports can be enhanced by good vision](https://reader036.vdocuments.us/reader036/viewer/2022062314/56649eb55503460f94bbd73f/html5/thumbnails/10.jpg)
Depth perception
• 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

Sunglasses• Prevent absorption of
UV light into the eye• Good for outdoor
sports such as cricket and tennis

![Page 19: Sports Vision. Performance in sports can be enhanced by good vision](https://reader036.vdocuments.us/reader036/viewer/2022062314/56649eb55503460f94bbd73f/html5/thumbnails/19.jpg)
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
![Page 20: Sports Vision. Performance in sports can be enhanced by good vision](https://reader036.vdocuments.us/reader036/viewer/2022062314/56649eb55503460f94bbd73f/html5/thumbnails/20.jpg)
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
![Page 21: Sports Vision. Performance in sports can be enhanced by good vision](https://reader036.vdocuments.us/reader036/viewer/2022062314/56649eb55503460f94bbd73f/html5/thumbnails/21.jpg)
Visual training
• 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
