Keeping a pet cat puts owners at greater risk of going blind, but a dog appears to protect eyesight, a new study suggests.

一项最新研究表明,养猫会增加主人失明的风险,但是养狗却能保护主人的视力。
 
Scientists have discovered that dogs and cats carry antigens which can prompt different immune1 responses in humans.
 
While the allergen which dogs carry reduces the chance of developing glaucoma – the second leading cause of blindness in the UK– owning a cat nearly doubles the risk of contracting the eye disease.
 
Many pet owners suffer mild allergic2 reactions to their pets but still choose to keep them. However the new study suggests that even a small immune response could lead to blindness.
 
The study by the University of California, Los Angeles, found that cat owners who reacted to their pet allergen had a 90 per cent increased risk of glaucoma compared with non-pet owners. But dog owners were 20 per cent less likely to develop the debilitation3 condition.
 
Keeping a dog also has the added benefit that owners are outside more which has been proven to protect against short-sightedness.
 
"Not only is Fido man's best friend, he may also save your sight," said British laser eye surgeon Dr David Allamby.
 
"Cats could cause our immune system to react in a way that predispose eyes to the development of glaucoma.
 
"Exposure to dogs appears to be linked to the opposite effect and could be protective against the disease."
