The role of optometrists in sports vision
• Correction of refractive errors
• Eye protection
• Visual training
Refractive errors
• Short-
sightedness,
long-sightedness,
or astigmatism
• Correctable with
glasses or
contact lenses
Normal focus
Short sightedness (Myopia)
Distance vision blurry, near vision usually ok
Short sighted focus Short sighted correction
Long sightedness (Hyperopia)Difficulty seeing clearly and comfortably up close
Long sighted focus Long sighted correction
Astigmatism
• The eye is shaped more like a football
than a basketball
• Focusing error that causes blur in one
direction
Binocular vision• Equal vision in both
eyes
• Provides stereoscopic
or 3D vision
• Good to have a
‘spare’ eye
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
Diagram of the eye
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
Conditions caused by extended exposure to UV rays
1. Pterygium
Conditions caused by extended exposure to UV rays2. Cataract 3. Age-related
macular degeneration
Eye protection• Especially in
squash, indoor cricket
• Lenses need to be plastic, not glass
• Damage can cause permanent blindness
Swimming goggles• Protect the
cornea from strong chlorine
• Can be worn with contact lenses, but only if they don’t leak
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
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
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
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
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
Optometrists
• Are university educated and undertake
continuing professional education
• No referral is required
• Eye tests are covered by medicare
