Like eyebrows, eyelashes help keep dirt, sweat, water, and other unwanted debris out of our eyes. Ironically, a stray eyelash may sometimes fall into the eye, causing temporary discomfort until it is removed. 1

The upper eyelashes are generally thicker than the lower ones, with about 200 lashes on the upper eyelid compared to around 100 on the lower eyelid. This difference helps provide more protection to the eyes from debris and particles. 2

The majestic giraffe possesses impressively long lashes. These lashes not only enhance the giraffe’s beauty but also protect the harsh environment of its natural habitat, where dust and debris can threaten its sensitive eyes. 3

Camels, resilient creatures of arid regions, have long, luxurious lashes that shield their eyes from the desert’s blowing sand and intense sunlight. These lashes are vital in preserving the camel’s vision and preventing potential damage. 4

Eyelashes grow in three phases: the active growth period (anagen stage), the transitional period (catagen stage), and the resting period (telogen stage). During the active phase, eyelashes can grow up to 16mm, as noted in research by Alzahrani et al., 2021. 5

You Jianxia from China holds the world record for the longest eyelash, measuring an astonishing 20.5 cm (8.0 in) on her left upper eyelid, confirmed on 20 May 2021. Her eyelashes have grown since she set the record on 28 June 2016, with an initial measurement of 12.4 cm (4.88 in).

Eyelashes provide a habitat for tiny mites called Demodex. These mites live symbiotically in our eyelashes, helping to remove dirt and debris from the lashes and cleaning the eyelash follicles, which can offer protection from eye infections. 6

Demodex blepharitis is caused by an overgrowth of microscopic mites (demodexes) inside the eyelash follicles. The first FDA-approved treatment for this condition is Xdemvy (lotilaner ophthalmic solution) 0.25 percent, manufactured by Tarsus Pharmaceuticals. 7

Aoi Nishifuji from Japan set the record for the fastest time to apply 100 eyelash extensions, achieving this feat in just 6 minutes and 58.74 seconds on 26 February 2020 in Kyoto, Japan. This remarkable speed showcases the precision and skill required in the eyelash extension industry. 8

Each eyelash has a lifespan of about three months, continuously falling out and being replaced. This cycle ensures that our eyelashes remain healthy and functional, much like other tissues in our body. On average, the upper eyelid hosts between 150 to 250 individual lashes. 9

The upper eyelashes typically measure 7-13mm long, whereas the lower lashes usually stay under 7mm. This length difference aids in shielding the eyes from environmental hazards. The length, curl, and thickness of your eyelashes are predominantly determined by genetics. 10

The color of your eyelashes is determined by the amount of melanin pigment they contain. More melanin results in darker lashes, while this pigment concentration can vary among individuals due to various genetic factors. 11

Eyelashes begin to form in the womb around the 20th week of pregnancy, preparing to protect the eyes even before birth. This early development is crucial for safeguarding vision from the start. That's a very critical period. 12

Historical records show that Ancient Egyptian women used charcoal to darken their eyelashes. This practice is one of the earliest forms of mascara, highlighting the long history of eyelash enhancement.

Early eyelash tools were used in Ancient Egypt, but the modern mascara we know today was created in 1913 in France by Rimmel. Mascara gained popularity in America after Maybelline introduced its first formula, a mixture of coal and Vaseline, which revolutionized eyelash enhancement. 13

Like hair, eyelashes require regular washing and conditioning to remain healthy and prevent damage or excessive shedding. Proper care can significantly improve their appearance and longevity. Otherwise, swear infractions occurred. 14

The beauty industry is delving into 3D-printed eyelashes, which could provide personalized options for length, curl, and color. This innovation promises custom-tailored designs to enhance individual aesthetics and expand creative possibilities in eyelash fashion. 15

Eyelashes evolved to act as a barrier against external elements, playing a crucial role in eye protection across various environments. Their primary function is to safeguard vision, which they perform perfectly. 16

It is normal to shed a few eyelashes daily, like losing hair strands. This shedding is part of the natural renewal process. It also ensures lash health and makes way for new growth of lash. 17

Eyelashes are primarily composed of protein, essential for their strength and flexibility. This protein structure helps protect your eyes by catching debris and blocking light, making them an important part of your eye's defense system. 18
