    Why Blue Light?

    I’m sure you’re all wondering. Why blue light? Is it fad, fact or fiction? Well we’re here to provide you a solid response to all those budding questions.

    Is it actually helpful or all just hype?

    Well let’s start with the facts first and get the boring part out of the way. 

    FACT: Blue light (HEV light) is the tail end of the visible spectrum of light you can visible see with the naked eye before you cross into the threshold of UV light. Blue light has a wavelength between 380nm and 500nm which makes it one of the shortest, highest energy wavelengths; just shy of the UV lights you feel from tanning beds, microwaves and etc. Prolonged and long-term exposure to blue light can cause serious long-term damage to your eyes.


    FACT: Blue light is everywhere (it’s what makes the sky blue) so exposure to it during the daytime helps boosts alertness, increase reaction times, elevates feeling of well-being. The second biggest source of blue light comes from the well-lit LED screens of your electronic devices i.e. cellphone, computer screens


    FACT: Blue light has its benefits during the day but exposure during the nighttime might be detrimental to your overall health. Prolong exposure at night can lower the production of melatonin, the hormone that regulates your sleep, and disrupt your natural circadian rhythm (the thing that tells you your sleepy at night) Lack of sleep can lead to very serious long-term issues to your health. After chronic exposure, you can also expect to reap long term growth of macular degenerations, glaucoma and retinal diseases.


    FACT: Digital eyestrain is real! Due to the onset and regular usage of media devices, most people have started developing symptoms of eye strain, blurry vision, headaches, neck pain, difficulty focusing and irritation. This does not only affect adults as children are also consistently exposed to the blue light from digital media devices.

    Okay now that we’re done with the nitty gritty. Why should you wear blue light glasses?

    1. They’re a great casual option to prevent the symptoms of digital eyestrain. Be free of those pesky dry eyes and headaches!

    2. More likely than not, you’re hovering around your cellphone checking your feed or for the latest and greatest anyways so browse away in actual comfort.

    3. Blue light blocking glasses actually see the most benefits when worn at night. They’ll help regulate your sleeping patterns without sacrificing your screen time. Especially helpful for those night owls that prowling around Netflix.

    4. Last but not least, you'll look amazing in them without looking like you're about to head to the gun range!
