Density of Eyelashes Vital to Eye Health

While fashion may dictate that long, thick, lovely eyelashes are ‘in’, scientists have announced that the optimal length of eyelashes is a third of the width of the eye.

This is based on the purely functional aspects of eyelashes – which are said to include –

    • to keep the eyes wet by channelling air flow
    • to repel dust/dirt from the eye
    • to trigger the blink reflex
    • to provide shade

    Now a group of scientists have measured eyelashes in proportion to eye openings on animal pelts at the American Museum of Natural History in New York and shown that lashes get longer as the eyes get bigger. On average, animals’ eyelashes were a third of the width of their eye opening.

    The human eye opening is about three quarters of an inch, or 20 millimeters, which makes our optimal lash length in the region of 7mm.

    Why Thicker Eyelashes are Beneficial

    Density of lashes was also found to be important. David Hu, a mechanical engineer at the Georgia Institute of Technology in Atlanta said:

    “The more dense you could make your eyelashes, the better it would be”

    This would be better at blocking airflow from the surface of the eye. In fact, camels have two rows of eyelashes to keep the sand out of their eyes.

    The researchers concluded that

    “Wearing curved false eyelashes of low porosity can potentially provide extra protection to the eye and reduce dry eye.”

    So it would appear that having eyelashes of the right length with a good thickness and density is not only attractive, it’s also good for your eyes too.
