Blue Light is the specific section of the visible light spectrum that can have harmful effects to our eyes and sleep.

Artificial blue light is emitted from LED lighting and from digital devices. Our close proximity to the device when viewing, especially over long periods of time, means that the harmful blue light can affect us and our children’s wellbeing.

The rays of the sun may appear to be colorless, but they're actually made up of red, blue, orange, yellow, green and violet hues. Red and orange are located at one end of the visible light spectrum, while blue and violet are at the other.

Red rays have long wavelengths, but produce less energy. At the other end of the spectrum, the wavelengths are shorter, but the energy is stronger. Because blue rays emit higher amounts of energy, they're more likely to affect your eyes.

Most of your exposure to blue light comes from the sun, but you can't avoid exposure simply by staying indoors. In addition to computer monitors and smartphones, blue light is produced by tablets, LED and fluorescent lights, LED light from TVs and compact fluorescent light bulbs.

Although blue light plays an important role in maintaining the sleep/wake cycle, regulating your mood and keeping your memory sharp, it may harm your eyes.

Long exposure to blue light may have been responsible for your symptoms. Blue light lowers the contrast on screens, causing the condition. Other factors that can contribute to eyestrain include poor lighting, failing to take regular breaks, less frequent blinking and dry air.

Long-term exposure to blue light may increase your risk of developing age-related macular degeneration (AMD). AMD occurs when the macula, the area of the retina responsible for central vision, is damaged.

It is known that light exposure suppresses melatonin secretion. Melatonin is a hormone which can influence circadian rhythms. Lower melatonin levels may explain the preliminary evidence of links to cancer.

Fluorescent light bulbs and LED lights do provide more energy efficiency than traditional incandescent bulbs. They also give off more blue light. Incandescent lights do produce some blue light, although less than most of the fluorescent light bulbs available.

During the two to three hours right before bed, avoid viewing bright screens.

Wear blue-blocking glasses or download an app to filter blue and green wavelength at night. This will help those that need to use electronic devices at night and individuals working night shifts.

Red light has the least influence on the circadian rhythm. Consider using dim red lights in bedrooms.

Add screen filters to computer screens, tablets and smart phones to reduce blue light emissions.

Use computer glasses that have yellow-tinted lenses that increase contrast and help block blue light.

Wear anti-reflective lenses to block blue light from digital devices and the sun.

Consider choosing an Intraocular lens (IOL) that protects eyes from blue light. This will replace a cloudy lens during cataract surgery.

For children, especially from birth to age three, the crystal lenses in their eyes are not fully developed. So it goes straight through, it causes a lot more damage in children’s eyes than it does in adults.

Blue light does affect the body’s circadian rhythm, our natural wake and sleep cycle. During the day, blue light wakes us up and stimulates us. But too much blue light exposure late at night from your phone, tablet or computer can make it harder to get to sleep.

Blue light from computer screens and digital devices can decrease contrast leading to digital eyestrain. Fatigue, dry eyes, bad lighting, or how you sit in front of the computer can cause eyestrain. Symptoms of eyestrain include sore or irritated eyes and difficulty focusing.

Studies suggest that continued exposure to blue light over time could lead to damaged retinal cells. This can cause vision problems like age-related macular degeneration.

After cataract surgery, the cloudy lens will be replaced with an intraocular lens (IOL). The lens naturally protects the eye from almost all ultraviolet light and some blue light. There are types of IOL that can protect the eye and retina from blue light.

Screen filters are available for smart phones, tablets, and computer screens. They decrease the amount of blue light given off from these devices that could reach the retina in our eyes.

I don't believe, in the 21st century, in the balance of power system. This is a European idea of the 19th and 20th centuries.

What you lack in talent can be made up with desire, hustle, and giving 110 percent all the time.

Games I do find interesting for what they say about us, about what we wish for, about the programming. But let it stop there: don't listen to this rubbish about them actually being good for you, helping with hand-eye co-ordination or whatever. They're games. They prepare you for nothing.

I love a girl that can make me laugh. I am not really a laugh-at-things type of guy and I don't smile and laugh all the time... But if a girl can make me laugh... I'm in love!!!!

I think it just came to a point where I made a decision to do better with my life and health. And that is only by God's grace because there are no guarantees.

The first book I sat down to write was an historical romance. It was really bad and thankfully no one ever saw it.

To be honest, I have never thought about getting into direction.

Once I'm committed to a role, I will go very deep into it, even when I'm not at work. I'll keep on studying the script, maybe 40 or 50 times. I might call a scriptwriter at three in the morning to say I've thought of something new.

Do not make grand plans. Be flexible.

If you have a fear of flying, don't. The data are very clear: If you have to travel someplace, the safest way is by airplane.

I like shows that are surprising and not predictable. That have deep, rich characters that are fully formed.

My eyebrows make a more profound impact on other people than they do on me. I just let em grow.

Things are beautiful if you love them.

We live in an ascending scale when we live happily, one thing leading to another in an endless series.

Cats rule the world.

The fool inherits, but the wise must get.

Acquiring Sunseeker deepens Wanda's international influence and represents an important step forward for the development of the business.

I get inspired by a lot of different stuff. My father is a huge music fan.

Usually people think that it is the musicians who create the music, but in fact it is music who creates the musicians.

I've never played an attorney, and I'd like to do so on a show like 'The Practice' or 'Law & Order.'

I deferred my third-year studies from university to go full time sailing to try and qualify for the 2012 London Olympics, which I did. I tried to go back to the university, but having won the silver medal, I just haven't been able to get back. And now I'm not sure if I ever will.

Loosen up, and everybody around you will loosen up.

The place to improve the world is first in one's own heart and head and hands.

Fear is the most debilitating emotion in the world, and it can keep you from ever truly knowing yourself and others - its adverse effects can no longer be overlooked or underestimated. Fear breeds hatred, and hatred has the power to destroy everything in its path.
