'Eyesight' in the Bible

"The eye is the lamp of the body. If then your eyesight is good, your whole body will be well lighted;

but if your eyesight is bad, your whole body will be dark. If however the very light within you is darkness, how dense must the darkness be!

The lamp of the body is the eye. When your eyesight is good, your whole body also is lighted up; but when it is defective, your body is darkened.

So they asked him, "How, then, did you gain your eyesight?"
