Surprising science. What do snow blindness and eyelashes have in common?

Tiny, delicate hair around our eyes are the best example how clever our organism is and what surprising solutions is offered by nature for each, even the smallest part of our body. Indeed, it is astonishing how big is the role played by the tiny lashes of ours.

Eyes are one of the most important elements of human body. Vision can’t be compared to any other ability we have. Thanks to this skill, we are able to discover world, win food and, in general, rule the reality that is around us. In prehistoric age capable eyesight used to determine one, the most important thing, which is survival.

Nature, in its surprising fastidiousness took care of our eyes to help them remain constantly protected. It didn’t only provide us with eyelids but also with the ability to blink. Moreover, our eye area features tear ducts to protect and moisturise eyes. Finally, we are also equipped with eyelashes and eyebrows.

For women eyelashes and eyebrows play mostly beautifying role, yet their primal function is more serious: eyelashes and eyebrows are supposed to shield eyes against impurities, dust, dirt, insects and even wind. Few know that eyelashes are also able to prevent (to some extent) snow blindness.

Snow blindness is caused by too strong and aggressive insolation. Intensive, too bright light leads to conjunctivitis. Probably everybody knows that this condition happens in snow-capped mountains and at high attitudes. However, it’s also worth realizing that snow blindness can also occur at the desert and beach. Also, this serious condition can be caused by exposing our eyes to too intensive light generated by spot lights (this happened to the Queen of Norway while she was giving an interview in a TV studio).

It is also proven that retina of people who have long and thick lashes is better protected against strong light. Perhaps eyelash serum, which is a cosmetic that extends and thickens the little hair around eyes, has another advantage? Can long eyelashes save us against snow blindness? Of course, we shouldn’t consider this as the only ultimate protection against the serious ailment, however, it’s worth realizing how much we own to our eyelashes while taking walks on hot, sunny days.
