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 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.

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 am learning to take control of my habits.

My position as the best-selling author at E! is secure - unless Salman Rushdie develops a show with them.

Americans, indeed, often seem to be so overwhelmed by their children that they'll do anything for them except stay married to the co-producer.

There is nothing wrong with making money, but it was just not in my family's habits to know how to do that. All we knew how to do was work, and we usually liked the work we did.

We're far more defined by our mistakes than the things that we succeed at.

Scientifically, happiness is a choice. It is a choice about where your single processor brain will devote its finite resources as you process the world.

Every renaissance comes to the world with a cry the cry of the human spirit to be free.

I can count all the ways in which being a mother has enriched my understanding of the world, of character, my sense of the future and my attachment to it. I can't imagine what kind of writer I'd be if I didn't have my kids.

I've always liked all the sciences, like math, physics and biology.

At the unveiling at the White House of the presidential portrait, President Bush pointed out that Hillary Clinton was the first sitting Senator in history to have her portrait hanging in the White House.

By preventing dangerous asteroid strikes, we can save millions of people, or even our entire species. And, as human beings, we can take responsibility for preserving this amazing evolutionary experiment of which we and all life on Earth are a part.

I've done films where we don't rehearse, and I've done films where we heavily rehearse. I like rehearsals.

Production and consumption of carbohydrates is so well regulated that there is a constant blood sugar level; any accidental increase or fall in blood sugar is rapidly compensated.

I love Sam Peckinpah.

I am sure that, on the one hand, the Rothschilds appreciate the merits of Marx, and that on the other hand, Marx feels an instinctive inclination and a great respect for the Rothschilds.

The fact is, funnily enough, that the people who seem to be most committed to causes also seem to be least invested in anyone actually talking to each other.

My teacher told my mum, 'I think William has dyspraxia,' and Mum asked what that meant. She said, 'Well, if I put a chair in the middle of the room and asked every child in the class to walk around it, William would be the only child in the class to walk into it.' Mum was like, 'Yeah, that's my boy'.

Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.

If I could help educate our children at an institution for higher learning, that would be a noble thing.

Live with your century; but do not be its creature.

The films I grew up loving, and the art that I love, is not generally the kind of postmodern ironic winking stuff. What lasts is the stuff in which the artists are totally in league with the subject.

I'm definitely bigger than a Rihanna. Pop stars nowadays are all perfect Barbie-doll bodies, and they talk about how they keep their bodies up with hard work, so in my eyes, it's good to have a regular, average body type in the charts.

The top athletes are consummate pros who work obsessively at their craft. Approach yours the same way.

I am a ordinary teenager. I fall in love like everyone else.
