“The eyes are the windows to the soul.”
This metaphorical expression is often used to describe the deep connection one feels when looking into another’s eyes (or their inner world). However, like windows, the eyes work both ways — meaning, they can provide a lot of insight into a person’s emotional state, feelings, and thoughts; they are also vital tools that influence how we view the world around us.
And if the eye is the window into the soul, the pupil is—quite literally—an opening into the eye. The pupil acts like the aperture on a camera, dilating or contracting to regulate the amount of light coming into the eye. This is why our pupils get smaller when exposed to light and bigger in the dark. This is called the pupillary light response. (Psychology Today)
Did you know that sight and vision are really two different things?
Sight is a sensory experience in which light plays a huge role in your ability to see and interpret physical objects. When light reflects off of shapes and objects, it enters the light-sensitive part of the retina in your eyes. This is where millions of concentrated cones (photoreceptor cells) receive the information and send signals along the optic nerve to the visual cortex of the brain, which then processes the information and converts it into images and colors.
Vision is a metaphysical concept that affects how the mind interprets the images that your eyes see. For example, if you see a car coming, you may envision that it’s not safe to cross the street until after the car has passes. Or, you may notice that the car is slowing down to give you the right of way. This may help you infer that it is now safe to continue walking across the street.
To put this into perspective, your ability to see may allow you to witness or partake in an event (e.g. a soccer game or wedding), but your vision is a bit more abstract in that it can help you understand the significance of a given event and encourage you to draw your own interpretations from it. Though sight and vision are different, they work harmoniously and are extremely important in empowering us to connect with our surroundings, to be safe, and to help keep our brains sharp.
With age comes greater health risks for your eyesight and vision.
Macular degeneration is the leading cause of vision loss, affecting more than 10 million Americans – more than cataracts and glaucoma combined. (AMDF) Often described as diabetes of the eye, this eye disease caused by the deterioration of the retina. It results in the loss of the central vision in your eye(s), making it more difficult to see shapes and objects clearly.
The retina is a vital part of the eye that captures the images we see and sends the information from the eye to the brain so that we can adequately interpret shapes and objects. More specifically, the macula, located in the central portion of the retina, is responsible for helping the eye focus on fine details. It controls your ability to do things like see objects, read books, and drive a car.
Here are some quick facts about AMD that you should know:
Things that you can do to prevent AMD and vision loss:
Don’t wait until it’s too late! Appreciate your eyes and give ‘em some love!
Junk light exposure when traveling can disrupt your circadian rhythm. Long-term exposure to light at night which accompanies shift work is listed as a probable carcinogen by the World Health Organization. Light at night has shown to be highly associated with significantly the risk of hormone specific such as cancers of the breast and prostate.
The flickering wavelength of light associated with LEDs and compact fluorescent lights emit blue light that inhibits melatonin production but also create a unique glare that impacts your retina causing eye strain, headaches, and physical and mental fatigue.
Red light and darkness move leptin and ghrelin into patterns that are (context dependent) associated with less hunger, while blue light does the opposite and can move both into patterns associated with more hunger.
Increase in cortisol, the stress hormone, due to circadian disruption. Memory recall is impaired with consistent sleep deprivation and may leave you distracted and not performing your absolute best.
The Importance of Melanopsin Cells
Your body requires some blue light at the right time of day and from the right sources. That’s why we created TrueDark® Sleep Technology that gives you 24-protection from junk light day and night.
Stop Junk Light with TrueDark® Twilight technology that frees your hormones and neurotransmitters to do their best work.
When the sun goes down, blue light isn’t the only junk light that can disrupt our sleep cycle and more than blue blockers are needed. TrueDark® Twilight is the first and only solution that is designed to work with melanopsin, a protein in your eyes responsible for absorbing light and sending sleep/wake signals to your brain. Without melanopsin, melatonin can’t be accessed.
When you wear your Twilights for as little as 30 min before bed you prevent your melanopsin from detecting the wrong wavelengths of light at the wrong time of day. This supports your circadian rhythm and helps you fall asleep faster and get more restorative and restful sleep.
The highly advanced lenses in TrueDark® Daywalkers operate on a more advanced level than traditional blue blockers.
Blue light emitted from the sun helps regulate our sleep/wake cycle. However, in today’s world, we’re exposed to an overabundance of blue light, or junk light from artificial light. This includes hours spent in front of TVs, phones, and computers. It also includes time spent in artificial man made light with LEDs and fluorescent lights. Even if we’re simply reading a book, we’re doing that in artificial light which emit dramatically more blue light than the sun. That overexposure to junk light during the day has a dramatic impact on our neurotransmitters and hormones that are responsible for quality sleep.
