戴眼鏡會損害視力嗎？

As we age, our eyesight can get worse. Although lenses can compensate for these changes, many people worry that wearing glasses will make their eyes become dependent on visual correction. In other words, they think if you wear specs, your sight will deteriorate even more.

隨著年齡的增長，我們的視力會變差。雖然眼鏡可以彌補這些變化，但很多人擔心戴眼鏡會使眼睛變得依賴眼鏡。換句話說，他們認為佩戴眼鏡，視力會更加惡化。

Thankfully, this is not how our peepers actually work.

謝天謝地，事實不是這樣的。

“Wearing glasses will not make your eyes worse,” says Michael J. Duerr, an optometrist in Rochester Hills, Michigan. “Your actual prescription is based on the anatomy of the eye: the front curve of the cornea, the refractive power of the intraocular lens, and the length of the eyeball.” And peering through spectacles won’t change that anatomy, Duerr says. “Wearing glasses or soft contact lenses will not change what your required prescription is.”

戴眼鏡不會讓你的眼睛變得更糟，”密歇根州羅切斯特山的驗光師Michael J. Duerr說。“眼鏡的模式是基于眼睛的解剖結(jié)構(gòu)的，”Duerr說，通過眼鏡看東西不會改變眼睛的解剖結(jié)構(gòu)。“佩戴眼鏡或軟性隱形眼鏡不會改變視力。”

But when you take off your glasses, the world seems blurrier than you remember. Does this indicate that you “need” your glasses more now than you did before you got them? Not necessarily. That change probably just means you’re getting used to seeing things clearly, according to the American Academy of Opthamology. Now that you know what the world is supposed to look like, it’s hard to go back—even if you thought your vision was fine before.

但是，當你摘下眼鏡時，世界似乎比你記憶中的更加模糊。這是否表明你現(xiàn)在比你之前更需要你的眼鏡?不一定。根據(jù)美國眼科學會的說法，這種變化可能只是意味著你已經(jīng)習慣于清楚地看清事物了。既然你已經(jīng)知道這個世界應該是什么樣子，那么很難回頭 - 即使你以前認為自己的視力很好。

It’s true that you may find yourself needing stronger and stronger prescriptions as the years go on, but again: This isn’t a result of wearing glasses. Our vision deteriorates as we get older, and chances are, you’ll need to upgrade your prescription from time to time.

確實，隨著歲月的流逝，你可能會發(fā)現(xiàn)自己需要更厲害的鏡片，但同樣：這不是戴眼鏡的結(jié)果。隨著年齡的增長，我們的視力會下降，所以你可能會需要不時升級眼鏡。

That brings us to another interesting worry: Some people fear that wearing an incorrect or outdated prescription can cause their eyesight to get worse. This is also a myth, at least in the case of adults—two studies found that incorrect prescriptions did slightly increase the progression of myopia, or nearsightedness, in children.

這給我們帶來了另一個有趣的擔憂：有些人擔心戴法不對或過時的鏡片會導致他們的視力變差。這也是瞎說，至少在成人以后 - 兩項研究發(fā)現(xiàn)，不正確的鏡片確實略微增加了兒童近視。

In addition, the special glasses given to children with crossed eyes or a lazy eye can actually change them—but in a good way. These aids help straighten the eye. The real harm comes from not using them, according to the Opthamology Department at Mayo Clinic Health System in La Crosse, Wisconsin: “Not wearing such glasses may lead to permanently defective vision.”

眼睛本身不正常的人如果不戴眼鏡就更糟糕，他們需要特殊眼鏡來幫助矯正，不戴就會惡化。

But don’t fear wearing glasses: There’s no evidence that the correct prescription will worsen eyesight in children or adults. As long as you stick with your annual or bi-annual checkups, you shouldn’t have anything to worry about. Wear your specs whenever you need them, and enjoy the privilege of seeing clearly.

沒有證據(jù)表明正確佩戴眼鏡會使兒童或成人視力下降。只要你堅持一年一度或每年一次的體檢，你就不必擔心什么。定期檢查，看清世界。
