What is interesting about Twinkle? Twinkling stars and eyes
Stars Twinkle because … they’re so far away from Earth that, even through large telescopes, they appear only as pinpoints. And it’s easy for Earth’s atmosphere to disturb the pinpoint light of a star. As a star’s light pierces our atmosphere, each single stream of starlight is refracted – caused to change direction, slightly – by the various temperature and density layers in Earth’s atmosphere. You might think of it as the light traveling a zig-zag path to our eyes, instead of the straight path the light would travel if Earth didn’t have an atmosphere.
Everyone knows this from the time they pee in the bed…Twinkle Twinkle little star, how i wonder what you are, up above the world so high, like a diamond in the sky. I write it because this is the first thing which comes up in the mind after reading Twinkle
Eyes Twinkle because …our eyes have received a fresh coating of tears. It’s a natural biological function and can be induced by blinking a few times, but there are emotional meanings traditionally attached.
Eyes looks sparkling when pupils are larger. What causes larger pupils? When a person is sexually or affectionately (e.g., without a sexual component – such as a parent to child or vice versa) attracted to another – pupil diameter will increase. More attraction equals more twinkle. Of course, a darker environment will also cause pupils to become larger. This is one instinctive reason why dimly lit restaurants are considered more romantic.
The angle of the light source-to the subject also plays a role. To give the greatest twinkle, it must be positioned behind the viewer (e.g. You). The source of the light may certainly influence the twinkle as well. If it is too bright – as very often is the case – it will cause the pupils to contract – thus detracting from the “twinkle”. A candle’s light source has the advantage of being dim (so as to engender larger pupils) and dynamic. This constantly changing flicker adds considerably o the twinkle-effect. And you wondered why candles were romantic?!
Partial eyelid closure component (If you want your smile to look sincere, you would close your eyelid partially as is emma watson’s eyes) of a sincere smile causing a deeper tear film on the surface of the eye. This leads to more reflectivity as well as a second reflection in each eye.
Another instance of sparkling eyes is when someone is trying to suppress crying. The tightened facial muscles trigger increased activity in the tear ducts and cause the person’s sight to shimmer–something which can often be seen by others–and forces the moisture into the nasal passages, which induces sniffling
Yes, Sometimes camera lights also makes eyes twinkle.
Be Twinkling. Have a Nice Day.
