How Do Blue Light Glasses Work?

Introduction

Ever wondered why when people spend more time watching TVs or surfing through digital devices like laptops, tablets, and phones report experiences of dry eyes, eye strains, irritations, headaches, blurred visions, and sleeplessness?

Blame that on blue light. Though the blue light is slightly longer and less potent than the UV waves and is too short for the naked eyes to see, they are considered harmful to your eyes by causing the aforementioned symptoms You will therefore need blue light glasses as your perfect solution. Here, we’ll have a closer look into the new-fangled technology of blue light glasses, whether they actually work, and the best blocking technology for your lenses.

What are blue light glasses?

Present-day interaction with technology has pushed people to spend more time working and socializing through digital spaces. The resultant effect is the over-exposure that makes your eyes experience symptoms of dry eyes, eye strains, irritations, headaches, blurred visions, and sleeplessness. These effects arise from the fact that your eyes are being affected by the emitted blue light from your device. Perhaps, now you need to start thinking of how to control and block off this emission. The most effective way for you is to rely on blue-light-blocking glasses here.

A brief literature reviews

Even though studies on blue light are still new and mixed, they do point out the negative effects of blue light on human. Symptoms associated with over-exposure to blue light largely revolve around digital devices, unlike the effect amount from the sun. While the sun is the biggest emitter of blue light, we are mostly affected by the emission from incandescent and fluorescent light bulbs and digital devices, given our widespread use of LED devices.

Research reports that adults spend approximately 6 hours daily while children spend 7 hours daily exposed to the blue light courtesy of digital devices. This is an over exposure. Learn more here 

Studies have also provided that exposure impacts your eyes by causing fatigue, eyestrain, sleeplessness, and headaches. Investigators have linked these findings to the fact that your eyes have structures that offer protection against some kind of light to your cornea, and the lens protects your light-sensitive retina at the back of your eyes against the damaging effects of powerful rays such as UV rays. However, these structures do not block the blue light you are largely exposed to. Learn more here.  

Though the blue light is not as intense as UV light, which could completely destroy your eyes, it causes the musculoskeletal and physiological issues that makes you feel fatigue, eyestrain, sleeplessness, and headaches. 

 

The side effects of harmful blue light

The side effects of blue light are not as potent as UV light for not all blue light is harmful to our eyes. The wavelength of blue light is between 380nm-500nm, during which the shorter the wavelength is, the larger the energy it emits. Such high energy emitted from blue light to our eyes will pose hazard to an extent. Typically, blue light in the wavelength between 400nm-460nm will do harm to us, which therefore, needs our attention. Though this is the case, you should note that the harmful effects of long-term exposure to blue light in the wavelength between 460nm-500nm can’t be ignored, which is still under investigations.

2. On sleep cycle

Sleep Vs Smartphones

    Exposure to blue light, such as through your phone, controls and messes with your sleep-and-wake cycle, the circadian rhythm. This occurs by blocking your melatonin hormone, responsible for making you sleep. This is essentially true during the night, where exposure to blue light hinders us from sleeping or feeling drowsy and makes us alert instead. More details

    What do blue light glasses help with?

    1. On human eye
    2. Reduce eye strain-This will enable you to enjoy your digital surfing moments by reducing eye fatigue, blurred vision, discomforts, and headaches.
    3. Protect your eyes-Using blue light glasses protect your eyes against the risks of a damaged light-sensitive retina causing a muscular degeneration that may eventually make you blind.
    4. Fewer Headaches- Wearing blue light glasses allows you to block the blue light that would otherwise lead to migraine attacks that exacerbate headaches.
    5. Makes you look professional: Wearing blue light glasses makesyou look professional and stylish while interacting out and with your digital devices.
    6. On sleep cycle

    The glasses will block blue rays from reaching your eyes at night, thus protecting you from the delayed release of melatonin hormone for your sleep. You will have better sleep considering an unaffected circadian rhythm.   Contest Code:LIVHO3

    How do anti-blue-light lenses work?

    As a solution to the blue light effect on your eyes, you will need to use anti-blue light lenses to block the blue rays from reaching your eyes. But do you know how this happens? The work is primarily based on two technologies; the technology of color infusion and anti-blue light coating.

    1. The technology of color infusion

    This technology works by coloring lenses, glasses, and the thermoplastic parts from clear, translucent, or opaque forms into colored lenses. The infusion technology works by placing the lenses in a heated bath holding a dispersion of dyestuff. The lenses are placed in the coloring solution until the preferred color depth is achieved. The dye infiltrates into the lens, removing color rub-off. The embedded colored resins on blue light lenses enable the lenses, and the parts adopt depth of colors that effectively block the harmful blue rays from reaching your eyes. More details here.

    Pros

    • A nice anti-blue light effect
    • Offers a cost-effective and environmentally friendlier option to the coating technology.

    Cons

    • This leads to visual effects in the daily use of lenses.
    • Makes lenses vulnerable to discoloration and aging.
    • Lowers the transmission of visible light.

    Aesthetic details

    • Lenses in pale and yellow-tinted
    • Yellow and orange lenses
    • Grey and red lenses.

     

     

    1. The technology of anti-blue-light coating

    Blue light glasses can work by adding anti-blue-light coating on glasses, particularly designed to prevent blue light from passing through the lenses. Such anti-blue-light lenses also can help to reduce glare too. The coatings are applied to your lenses on either one side or on both the front and the back sides to control the amount of blue light that gets into your eyes. Still, this application could either be one-sided film coating or two-sided film coating.

    One-sided film coating

    Occurs when a thin multi-layer coating that eliminates glares and reflections of blue light is applied on one side of your lenses surface.

    Pros

    • The lenses are transparent and clear without tint.

    Cons

    • Brighter reflection will affect lenses appearance;
    • The lenses' inner surface will reflect harmful blue light into the eye

    Aesthetic details

    • No tint but an intense reflection

    Double-side film (coating)

    This works by applying a thin multi-layer coating that eliminates glares and reflections of blue light from both sides of your lenses. Specifically, the procedure involves applying a high-reflection film of blue light to the outer surface while applying an anti-reflection film to the inner surface.

    Pros

    • Lenses are transparent and clear
    • High transmittance

    Cons

    • Lower blocking rate of blue light.

    Aesthetic details

    • The lenses are yellow-tinted.
