  • Curious how good your eyesight is? Take a look at this image.

    很好奇你的視力到底多好嗎?看看這張圖片吧

  • Who do you see?

    你看到了什麼

  • If you're at a normal viewing distance from the screen and have decent eyesight,

    如果你在適當的觀看距離,並且視力還不差的話

  • you should be seeing Albert Einstein.

    你應該會看到愛因斯坦

  • However, if you see Marilyn Monroe, you may want to consider wearing glasses or contacts.

    但如果你看到的是瑪麗蓮夢露,你可能就要考慮戴眼鏡或隱形眼鏡了

  • Wear your glasses right now. Try taking them off and the image may change.

    戴上你的眼鏡吧!然後再把眼鏡拿下來,你會發現圖片好像改變了

  • Or if you're near somebody else, ask them what they see.

    或是,如果你旁邊剛好有人,問問他們看到了什麼

  • The effect can actually be seen by anyone if we change the distance or size of the picture.

    任何人都看得到這種變化,只要改變了視距或圖片的大小

  • If it's far away, you're more likely to see Marilyn Monroe, as our eyes only pick up the broader strokes of an image from a distance.

    如果圖片離你很遠,你應該會看到瑪麗蓮夢露,因為我們眼睛只會從遠處看到圖片上比較粗的框線

  • But as you come closer to the image, you see the finer details of Einstein.

    但當你離圖片越來越近時,你會慢慢看到愛因斯坦身上的細節

  • We promise we haven't changed anything digitally.

    我們保證沒有修過圖片

  • In fact, pause this video now, and try walking away from your computer screen.

    事實上,按一下暫停鍵,然後試著離你的螢幕遠一點

  • Chances are the image will change and at a different distance than your friends because our eyes are all slightly different.

    這些圖片很有可能會跟著改變,然後你也會與你朋友站的距離不一樣,因為每個人的視力有高有低

  • The further away you can stand and still see Einstein, the better your eyes likely are.

    當你站在越遠的地方還能看到愛因斯坦,這表示你的視力越好

  • You can achieve the same effect by squinting your eyes to blur the photo.

    把你的眼睛瞇起來直到視線變模糊,這也可以達成一樣的效果

  • So what's going on? Well this image is an example of a hybrid image, whereby a low spatial frequency of one picture is combined with the high spatial frequency of another.

    所以為什麼呢?是這樣的,這張圖可以算是混疊圖像的一種,其中高低不同的空間頻率會混和在一塊

  • But depending on how well you're able to focus or pick up contrast, your eye will only pick out certain details.

    取決於不同眼睛對焦及判斷對比的能力而定,你的眼睛只會從圖片抓出一些特定的細節

  • Up close, we're generally able to see fine details like Einstein's mustache and wrinkles.

    近點看,我們大多能看到愛因斯坦清楚的細節,像是鬍子及一些皺紋

  • But as the distance increases, or if your vision is poor and creates a more blurred image in the first place,

    但隨著距離增加,或是你的視力本身就不好,一開始你會看到比較模糊的圖片

  • Your ability to pick up details fades away.

    你看到細節的能力會逐漸減弱

  • Instead, you only see the general features like the shape of the mouth, nose and hair, making it seem like Marilyn Monroe.

    相反地,你只會看到一些比較普通的細節,像是嘴巴的形狀、鼻子及頭髮,讓這人像趨近於瑪麗蓮夢露的樣子

  • Love tricking your brain with illusions?
