白内障不仅仅是人类特有的疾病。动物界也有白内障这种病，但是对于动物们来说，得了白内障就等于失明了，这些宠物的主人们希望能够让宠物宝宝尽可能“享受人生”。所以动物宝宝也可以戴眼镜了！

当然，传统意义上的眼镜是不能戴在动物脑袋上的！德国发明了隐形眼镜帮动物宝宝们接触白内障带来的痛苦，究竟是怎么回事呢？看看下文吧。

A German company has produced contact lenses for animals, including lions, giraffes, tigers and bears, who suffer from cataracts.

S & V Technologies, founded by Bavarian chemist and entrepreneur Christine Kreiner, have created the acrylic intraocular lenses which are custom made to fit each animal.

"Cataracts generally means blindness for animals, unlike for humans," said the head of the company's veterinary division, Ingeborg Fromberg.

"And because animals have short lifespans, it means losing quality of life in a greater share of that life."

Since its launch in 2008, the firm has fielded calls from Sea World in San Diego (a sea lion who had trouble performing his tricks due to severely blurry vision), an Australia nature park (a blind kangaroo) and a Romanian zoo (a visually impaired lioness).

Special lenses that absorb UV rays can also be used to help horses afflicted with "head shaker syndrome", an excruciating and ultimately life-threatening ailment.

Although the expense of such an operation and subsequent check-ups can run into the thousands of pounds, the procedure is often worth it for animals that have gone blind – and for their owners.

S & V posted turnover of around £2m last year.
