He braked suddenly as a jackrabbit darted into the bright cones of light.

当一只长耳大野兔出现在车灯光圈里时，他突然刹了车。

《柯林斯英汉双解大词典》

When they detect light, rods and cones pass the visual signal from nerve cell to nerve cell to the visual processing part of the brain.

当光线被这些感受器感受到时，杆状和锥状细胞就把视觉信号从一个神经细胞传到另一个神经细胞，一直传送到大脑负责成像处理的区域。

It gradually destroys the rods and cones that detect light in the retina of the eye. But it does not harm the optic nerve, which transmits electrical impulses from the retina to the brain.

这种病会逐渐破坏视网膜可以感光的视杆和视锥，但是不会损害视觉神经，视觉神经负责将视网膜神经脉冲传递到大脑。

The hope is that this will prevent crucial light-sensing "cones" inside the retina from degenerating.

FORBES: Banishing Blind Spots

The artificial retina is composed by neuronal photoreceptors, called cones and rods, which capture light signals and transform them in electrical signals, transferring them to the retinal ganglion cells and, through the optic nerve, to the brain.

Perhaps you recycle your cardboard and Coke cans, but if you're looking for a bit of inspiration from master design-recyclers check out this pendant lamp made from hundreds of soda tabs, this Cone Light made from repurposed traffic cones, and this chandelier composed almost entirely of six-pack rings.
