电脑验光准确吗?

答案

参考答案:

自动验光仪是屈光检查技术和电子计算机结合,又叫电脑验光仪。此种验光仪种类较多,但都有误差,误差的多少主要与验光技术员动手术训练程度,被检者年龄,屈光状态,屈光间质混浊情况有关。有人认为虽然仪器中装有无调节装置,但被检眼一接近仪器,就产生调节,形成近视,因此结果产生近视度数偏高,远视度数过低,对青少年就更不准确。电脑验光的结果只能作参考,不能直接作配镜处方。电脑验光仪有操作简易,验光速度快的优点,且多为进口价格昂贵的仪器,不少人盲目信任。许多眼镜店用此炫耀,显示验光配镜水平高。但严格地说,验光师应由受过正式培训的人或眼科医师耒担任,才能有配镜处方权。

A heartless thief is believed to have crashed a fund-raiser and made off with a bag of cash meant to help a New York City firefighter pay for life-changing surgery for his 9-year-old son. But little Aidan Sullivan -- who was born with a facial defect and no right ear -- yesterday put up a brave front, with a message for the crook(thief): "I'm going to kick your butt!"

"I want to look normal," said Aidan, whose father, Tim, is a firefighter in the Bronx. The third-grader has hemi facial micro soma, in which one half of the face doesn't develop correctly.

Last weekend, family friend Peter Drake, a Ridgefield, Conn., firefighter, hosted a fund-raiser, collecting between $8,000 and $9,000. But when the party at a Danbury, Conn., Irish cultural center was over, the money had disappeared.

"At the end of the night, all the money that was donated was put in a zippered bag," said Tim Sullivan. "A bartender gave the bag to Pete... He had it in his hands. He put it down to go do something, and when he came back, he saw that it was missing."

Sullivan said his longtime friend -- who has had fund-raisers to pay for Aidan's 10 previous surgeries -- is "devastated."

"Pete was so upset. He kept saying, 'I let Aidan down, I let Aidan down,” Colleen Sullivan, 40, recalled.

"We even went Dumpster diving, in case it was thrown out."

The Sullivans plan to go ahead with the March 1 surgery led by specialists at NYU's Langone Medical Center in Manhattan. The money would have offset the $10,000 to $15,000 that insurance doesn't cover. Yesterday, Aidan said he's not a fan of hospitals and doesn't like to be away from his sister, Kaylee, 4. But he's willing to do it. "I'm excited," he said. "Finally, an ear."
