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.

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.

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 enjoy public performances and being up on a stage. I don't enjoy the glamour. Like tonight, I am up on stage and my feet hurt.

To slow down is to be taken into the soul of things.

It was awesome and liberating to play a Russian spy.

In all honesty, we all want our fantasy selves to be the best people. We all think in a time of crisis, we will react heroically and with humanity.

Its all about quality of life and finding a happy balance between work and friends and family.

Give me today for once the worst throw of your dice destiny. Today I transmute everything into gold.

If you think your body and mind are two, that is wrong; if you think that they are one, that is also wrong. Our body and mind are both two and one.

Time when learning how to learn and unlearn is central to success. Instead of hiding from change lets embrace it. Each time we try something new we get better at getting better. Experience builds competence and confidence so were ready for the big changes like re thinking what we do.

We are less when we don't include everyone.

You'd go to a Pakistani party and the men and women would go in at the front door and the women would go to the right and the men would go to the left, and that was the last that we'd see of them until we were coming home.

But I do have an idea in my head before I go in about what I'm going to do.

I haven't ever seen 'Lost'... I'm sorry.

Helping others is like helping yourself.

Sometimes, to regain sanity, one had to acknowledge and embrace the madness.

The State of Israel was not established by anxiety but, rather, through pride.

It's never one solitary event that has changed my life. It's a bunch of little pieces that built and built up to where I am now.

I ran track. I ran cross country. But I did not play organized basketball in high school, at least on our team. But I played a lot of sports.

We cannot control the evil tongues of others but a good life enables us to disregard them.

If you raise taxes on millionaires and billionaires, you'll do nothing to address the debt and the deficit. And the thing you might do is you might finally put this economy over another cliff. These millionaires and billionaires are the folks that try to create jobs and help grow the economy.

There are 36 ways to tell this story. And all of them are disgusting.

Because there are little to no consequences for conducting cyberattacks, criminals and nation-states are becoming bolder in their threats and behavior. Russia, China, North Korea and Iran are increasingly hacking into U.S. companies and government networks for espionage purposes or financial gain.

Complexity that works is built up out of modules that work perfectly layered one over the other.

We're aiming to be the leading investment platform for the clean-energy economy.

Bush's war in Iraq has done untold damage to the United States. It has impaired our military power and undermined the morale of our armed forces. Our troops were trained to project overwhelming power. They were not trained for occupation duties.
