MYTH #2. EATING CARROTS WILL HELP YOU SEE IN THE DARK.
误解2:吃胡萝卜能增强你的夜间视力
Well, carrots certainly aren't bad for your eyesight. They contain plenty of beta-carotene, which your body converts into vitamin A, a crucial vitamin for vision. But carrots don't do anything exceptional for your nighttime vision.
其实胡萝卜对你的视力没有坏处,它们含有丰富的β-胡萝卜素,随后你的身体会将它们变成维他命A,这种维他命对视力至关重要。但胡萝卜无法让你的夜间视力变得超常。
MYTH #3: THE BIGGER YOUR EYES, THE BETTER YOUR EYESIGHT.
误解3:你的眼睛越大,视力越好。
When you're born, your eyeballs are approximately 16 millimeters in diameter, reaching 24 millimeters as an adult. But your eyes getting larger does not necessarily mean that your vision is getting better. In fact, excessive growth in human eyes can cause myopia, or nearsightedness. If the eyeball is too long, the eye's lens can't focus the light in the right part of the retina to process images clearly.
人类刚出生的时候,眼球直径约为16毫米,成年后会达到24毫米。但你的眼睛变大了并不意味着你的视力变强了。事实上,人类眼睛过度增长会造成近视。如果眼球太长,那么眼睛的晶状体就无法将光线聚集在视网膜的正确位置,人类也无法接收到清晰的图像。
