If
you want to wink, there are no good eyelashes. A pair of
long eyelashes can make you more beautiful, but the eyelashes won't be as long
as possible. In fact, its golden ratio to the eyes can better protect the eyes.
We
all know that
lashes are used to
protect our eyes, but how to protect them is not very clear. Some people think
that eyelashes can protect our eyes from dust. Others believe that eyelashes,
like the antennae of an animal, can detect foreign objects and close their eyes
before they are injured. In fact, the eyelashes do not directly protect the
eyes, but instead change the airflow around the eyes, prevent dust and other
irritants from entering the eyes, and let the water vapor flow. Some people try
to use a small plate filled with water as the "eyeball", a plastic
mesh to simulate the "eyelashes", and a small fan that is taken out
of the computer to blow the "eyes." Then carefully record the amount
of water evaporated from the eyeball and the amount of dust that the fan blows
into the surface of the eyeball. The results show that the length of the
eyelashes has a golden ratio. When the length of the eyelashes is close to 1/3
of the width of the eye, the eyes evaporate and the dust falls on the eyelashes
at least.
The
eyelashes create a slow-flowing air at the boundary layer that not only
prevents dust from flowing, but also keeps the eyes moist and keeps the water
dry. The longer the eyelashes, the thicker the boundary layer, but the longer
the eyelashes, like the funnel, directing the flowing air into the eyes and
damaging the protective layer. There are many beautiful girls who will pursue
artificial
lashes. Although very
beautiful, it is not good for the eyes. People with short eyelashes do not
think this aspect is flawed. Although it is better to protect the eye from the
best eyelash length, it is enough for the normal operation of the eyeball.
