Eyelashes are a first line of defense for your eyes, keeping airborne dirt, dust, lint and other debris from reaching the delicate eye tissues. With eyes open, eyelashes catch some airborne debris, but when closed, eyelashes form a nearly impenetrable barrier against foreign irritants in the eye.
if we don't have eyelashes our eyes won't get protection from dust and sun. hence,our eyes would be affected and we may have eye problem.
Humans are not the only animals that have eyelashes — all mammals have them, including cats, dogs, elephants, and mice. But they differ in length and density depending on where the animal lives. In most cases, other animals also have much longer lashes on the upper lid.
Growth Cycle of Baby Eyelashes
As mentioned before, eyelashes start to develop on a baby in the womb at around 20-22 weeks. But it will take some time for those same eyelashes to become visible after the baby is born. Rest assured that as your baby grows older, hair, eyebrows, and eyelashes will also grow.
The color of your eyelashes, just as your hair, greatly depends on the amount of melanin pigment they contain. The larger the amount of melanin the eyelash contains, the darker the color (and vice versa).
After all, you don't need to cut them like you do the hair on your head, do you? Eyelashes do indeed grow, though. They help protect your eyes by keeping dust and other debris away. When your eyelashes sense foreign matter that might harm your eyes, they trigger a reflex that makes you blink and close your eyes.
They're long and sensitive. When something touches them, it triggers the blink response as a defense mechanism. Without the eyelashes, it would take longer for the blink response to activate, because the main trigger would be seeing something coming at the eye, Marioneaux said.
They make your eyes look bigger:
Whatever shape or colour your eyes maybe, long black eyelashes make them open up, look bigger and brighter. This is a scientifically proven fact that baby-like features such as big eyes induce feelings of love and attraction in other adults.
An autonomic reflex is a motor action that your body makes in response to a stimulus. It doesn't involve a conscious decision on your part to take that action. It's possible to sneeze with your eyes open, but most people have to make a concerted effort to override their reflex to keep their eyes open.
Eyelashes can grow back if pulled out, but it may take longer than 6 weeks or longer. This is because pulling an eyelash slows down the process of regrowth. While it's quite normal to lose 1-2 eyelashes a day, significant eyelash or eyebrow hair loss (madarosis) may indicate a more serious problem.
They protect our eyes from moisture and light
Ever notice how your eyebrow hairs grow outward, toward the sides of your face? That helps direct any moisture away from your eyes toward the side of your head. Eyebrows can also reduce the amount of light that gets into your eyes and keep dirt away from them, too.
We have a myth going around that if you cry regularly, your eyelashes will grow longer. But does this work? Researchers believe the experience is related to how stress hormones like cortisol affect the hair follicles. The release of these hormones may increase growth, but they are unlikely to cause longer eyelashes.
You Jianxia from China broke her own record for the longest eyelash measuring 20.5 cm. You Jianxia has held the Guinness World Record title since June 28, 2016. At that time, her eyelash measured 12.4 cm, on the upper eyelid of her left eye. But she continued to grow her eyelashes.

The human eye is an organ that detects light and sends signals along the optic nerve to the brain. Perhaps one of the most complex organs of the body, the eye is made up of several parts—and each individual part contributes to your ability to see.
What causes trichomegaly in families? While it's rare to have super long lashes with no other symptoms, it does happen. To better understand the genetics of long lashes, scientists decided to look at familial trichomegaly.
Men, on average, have more hair than women, which is owing to the higher levels of testosterone hormones in their bodies. As a result, they have longer lashes than women who are often less hairy, if not completely hairless on most body regions.
"Generally speaking, otherwise healthy eyelashes grow about 0.15 millimeters per day and are typically about seven millimeters long (beyond the skin). So, doing the math, it takes one to two months to grow a normal-length eyelash from scratch," says King.
The life span of an eyelash can vary from 4 months to as long as 11 months. There are three phases to this life span: the growth phase, the degradation phase, and the telogen phase. Growth phase. Also known as the anagen phase, this phase may last between 4 and 10 weeks.
Aging. Aging is the most common reason why eyelashes go white. Your hair tends to lose melanin as you age. As melanin declines, your hair turns gray and later turns white as levels continue to decrease.
Being naturally blonde is pretty rare.
Only 2 percent of people in the world are natural blondes. (About one in 20 Americans are.) But that doesn't mean it's not popular. One in three women dyes her locks light enough to be considered blonde.
