What is UV?
• Ultra Violet radiation is a component of
solar energy
• Most solar UV radiation is absorbed by
the ozone layer
• More than 36,000 additional cases of
eye problems will occur from ozone
depletion

Eye damage thought to be caused by UV radiation
• Cataracts
• Pterygium
• Cancer of skin around eye
• Photokeratitis
• Corneal degenerative changes
• Age-related macular degeneration

UV light can be absorbed by the cornea

Cataract
• Cloudiness in
lens of eye
• Usually gradual
loss of vision
• Common after
60
• May require
surgery

Pterygium
• Like “skin” growing onto cornea
• Bumpy surface gives irritation and redness
• Is removed if close to centre of eye

Lid lesions
• Likelihood
increases with age
• Look for any
change in size
• Any new lesions
should be checked
ASAP

Photokeratitis
• Occurs when exposed to large amount of UV (skiing, water sports)
• Pain, watering, red eye
• Easily prevented with eye protection
![Page 11: UV and your vision. What is UV? Ultra Violet radiation is a component of solar energy Most solar UV radiation is absorbed by the ozone layer More than](https://reader038.vdocuments.mx/reader038/viewer/2022103111/55141d9f550346dd488b5693/html5/thumbnails/11.jpg)
Corneal degenerations
• Can be from build up of UV over the years
• Cause pain, tearing, redness, light sensitivity
• Difficult to treat

UV light can also be absorbed by the retina

Age-related macular degeneration
• Deterioration of central retina
• Affects close vision
• Distorted vision, patches missing
• Some treatment available

Sunglasses• Wrap around is good
• Australian standards
• UV protection
unrelated
to price
• Choose a colour tint
that is comfortable
