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.

Seek more strength for weaker spine. No grape grows on sinners vine

I do not believe it is all about the leader. I think it's about the team, too. So we have one mission; we have one team; we are working to victory.

The funny thing in France is that writers are not allowed to retire, because the French government say you are still earning money from books you wrote 20 years ago.

It seems like all the good looking people have smaller dogs these days. Especially for the women, because they always come in with their little Chihuahuas and the guys come in with their Golden Retrievers.

Feminism is like any female-dominated group - a perpetual catfight.

I accomplished something big and that's a memory I will never forget.

I could have been known for something terrible.

Never stop dreaming, and never stop working hard for your dreams. You never know what you can become. Life is unpredictable. You will never know as to which road can leads you to which destination.

I spar with Nick and Nate Diaz... those boys know what they're doing; they can throw their hands.

'Cause shade never made anybody less gay.

I think the Democratic Party is about family, about unity, about bringing people together. We're all in this together. We're all trying to rebuild the economy together.

I've been careful in love. I've been careless in love. And I've had adventures I wouldn't trade for anything.

Ancestral karma is not something that is permanently ingrained; with conscientious effort it can be modified and healed. It only requires you to be proactive and intentional in your efforts to heal.

You can't write a screenplay if you've been doing a zero-hours contract. Which means that the people who write drama, the people who commission dramas, and the people who direct dramas all come from a small circle of society.

I believe that every human mind feels pleasure in doing good to another.

On the first day of a college you will worry about how will you do inside the college and at the last day of a college you will wonder what will you do outside the college

You grow up the day you have your first real laugh at yourself.

What we want to do is make a leapfrog product that is way smarter than any mobile device has ever been, and super-easy to use. This is what iPhone is. OK? So, we're going to reinvent the phone.

At this point, I don't get hired a lot because people don't think I could finance a movie.

Within the microcosm of a film you get drawn to people. There are certain projects you care enormously about, and 'The Edge Of Love' was one because I was portraying a great hero of mine, Dylan Thomas.

This idea that being youthful is the only thing that's beautiful or attractive simply isn't true. I don't want to be an 'ageless beauty.' I want to be a woman who is the best I can be at my age.

Often, farmers have difficulty finding secondary markets for their outgrades and have no choice but to leave fresh produce unharvested to rot in the field. Gleaning Network U.K. coordinates teams of volunteers with willing farmers across the U.K. to direct this fresh surplus produce to charities that redistribute it to people that need it most.

The United States armed forces and coalition troops deserve recognition and support for their work to remove Saddam Hussein from power, and ensure the safety and security of the American people, civilians abroad, and the people of Iraq.

My vegetable patch is my pride and joy.
