Performance in

sports can be

enhanced by good

vision

Page 3: Sports Vision

The role of optometrists in sports vision

• Correction of refractive errors

• Eye protection

• Visual training

Page 4: Sports Vision

Refractive errors

• Short-

sightedness,

long-sightedness,

or astigmatism

• Correctable with

glasses or

contact lenses

Page 5: Sports Vision

Normal focus

Page 6: Sports Vision

Short sightedness (Myopia)

Distance vision blurry, near vision usually ok

Short sighted focus Short sighted correction

Page 7: Sports Vision

Long sightedness (Hyperopia)Difficulty seeing clearly and comfortably up close

Long sighted focus Long sighted correction

Page 8: Sports Vision

Astigmatism

• The eye is shaped more like a football

than a basketball

• Focusing error that causes blur in one

direction

Page 9: Sports Vision

Binocular vision• Equal vision in both

eyes

• Provides stereoscopic

or 3D vision

• Good to have a

‘spare’ eye

Page 10: Sports Vision

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

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

Retinal damage

Normal retina

Damaged retina

Page 14: Sports Vision

Conditions caused by extended exposure to UV rays

1. Pterygium

Page 15: Sports Vision

Conditions caused by extended exposure to UV rays2. Cataract 3. Age-related

macular degeneration

Page 16: Sports Vision

Eye protection• Especially in

squash, indoor cricket

• Lenses need to be plastic, not glass

• Damage can cause permanent blindness

Page 17: Sports Vision

Swimming goggles• Protect the

cornea from strong chlorine

• Can be worn with contact lenses, but only if they don’t leak

Page 18: Sports Vision

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

Page 19: Sports Vision

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

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

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

Page 22: Sports Vision

Optometrists

• 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

Page 23: Sports Vision

Optometrists

• Are university educated and undertake

continuing professional education

• No referral is required

• Eye tests are covered by medicare
