Why does it take longer to open-and-close one eye (wink) then two eyes (blink)?
You would think it would take less time to just close one.

Winking is a voluntary action requiring different muscles, therefore you need to think about it and then have the correct muscles respond as compared to blinking which is an automatic reflex.

Blinking is an autonomic movement that developed to keep the eyes moist without interfering noticeably with vision. It's quick and usually unconscious. Winking doesn't serve a practical purpose that can't be better served by blinking, so it never became autonomic. You have to close one eye while resisting the urge to close the other one with it. That takes conscious thought and and a discoordinated effort between muscles that are used to working together. (Compare rubbing you stomach with one hand and patting your head with the other.)

it is not any longer proper in case you have one eye, 2 eyes or twenty eyes. in case you blink, you're making a reflexive action. Blinks are very rapid and an excellent type of the time we not often additionally be conscious that we are blinking. We blink to maintain our eyes moist, and to avert getting airborne dirt and dirt, airborne dirt and dirt, smoke or despite in our eyes. A wink, on the different hand, is a planned action. A wink, via the way, is lots slower than a blink.

Blinking in an involuntary movement that our eyes make to keep them moist.
Winking is a conscious effort and we can control the duration of the wink. Plus it takes more effort to use the muscles voluntarily instead of involuntarily like we normally do.

blinking is the body's natural way of keeping the eyes moist winking is a controlled conscious movement

Blinking involves the movement of the muscles in your eyelid.
Winking involves the movement of those eyelid muscles and muscles in your cheek, so it requires more effort to wink than blink

Blinking is a natural occurence, winking is a forced motion.

maybe cause we are so used to blinking both at the same time that it takes more effort to blink only one of them

It would assume because it takes more effort to open and close one eye rather than both.
