The Idea from Leonardo da Vinci? 來自達(dá)·芬奇的啟示

隱形眼鏡的設(shè)計最早可以追溯到達(dá)·芬奇。在一份1509年的手冊中，達(dá)·芬奇寫道，把頭伸進(jìn)盛滿水的半球型玻璃缸向外看，發(fā)現(xiàn)原本看不清的物體變得清晰了。受這一原理的啟發(fā)，人們想出了各種辦法。有人提議可以將充滿水的軟管直接附著于眼球表面，但是這一方面有個大難題：無法眨眼。

The design of the contact lens can be traced back to Leonardo da Vinci who, with a bowl of water, kicked off the whole cringe-worthy history. In a manual published in 1509, da Vinci noted that when you stick your face in water, you see things differently. He wasn't really talking about correcting vision at this point, but manipulating the cornea's power is the idea behind the contact lens at its most basic.

From there, it was a natural progression to assume that a tube filled with water smacked directly against the eyeball would do something cool.The problem: Right on top of the eye meant no blinking allowed. [/cn]Other proposals included tubes held snug to the eyelids with a headband and capsules filled with "animal jelly." None were viable. None saw real-world testing.
