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.

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.

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.

Good grooming is integral and impeccable style is a must. If you don't look the part, no one will want to give you time or money.

When they meet a stand-up comic, people sometimes remark: 'That must be the hardest job in the world.' Among comedians, only Freddie Starr is not embarrassed and slightly appalled by this remark.

The myth of Good Guys and Bad Guys is one of the most pervasive we own, and morally grey anti-heroes are simply one of modern fiction's attempts to shake off that mythology and replace it with something a bit more honest.

What destroys more self-confidence than any other educational thing in America is being assigned to some remedial math when you get into some college, and then it's not taught very well and you end up with this sense of, 'Hey, I can't really figure those things out.'

I don't like to be a preacher or anything, but the one thing that I've learned is that you truly are what you eat.

And in Iraq we tried to implement the same policy that was so successful in Saudi Arabia, but Saddam Hussein didn't buy. When the economic hit men fail in this scenario, the next step is what we call the jackals.

Adversity tests us from time to time and it is inevitable that this testing continues during life.

You shouldn't get to live in society and give nothing back. People complain about their taxes, yet they do nothing for the community. That makes me furious.

I thought I was the coolest kid in the world, so I wound up being the coolest kid in the world.

As far as I am concerned, I write novels, and other people can do the labelling.

It is every mans obligation to put back into the world at least the equivalent of what he takes out of it.

I am trying to give whatever little fans I have as much information as they want from me. I don't want to come across as arrogant or mean by not telling or giving them what them I want. These are the people who make you a star.

So many of the major decisions that affect the entire future of your enterprise happen during its first year in business. In fact, most don't make it because they don't know how to get the resources they need to survive.

We are a nation of laws, and we will always act within the bounds of the law.

I never even wanted to be an actress. I studied mass communication and wanted to study law in Newcastle, for which I even got a scholarship. But by then, I had started modelling. So, I took a year off to decide what to do. But once you are used to working, it's difficult to get back to studies.

I went to dance class as a girl because I didn't like sports, but I never did a dance recital in my life. Never, ever, ever. I felt comfortable dancing, and I was happiest dancing, but I was never the best person in the class.

Personally, love is very important for me. There are lots of ordinary things in life, so love should be extraordinary. I hope I achieve that.

I think what weakens people most is fear of wasting their strength.

The war in Iraq, the abuse of detainees, electronic eavesdropping, Guantanamo Bay - these things were all done on our behalf and they may turn out in the end to have created more terrorists.

The question of societal fairness is always pertinent.

Some people just use beautiful things to just shop or to have a tribal feeling - 'Oh, blah, blah, blah, I'm wearing Hermes; blah, blah, blah, I'm wearing Saint Laurent; blah-blah blah' - because it's like a need, a tribe, recognition: 'Ahh, my Rolex.' But I run away from anything which is too recognizable - it's my nature.

I have looked into your eyes with my eyes. I have put my heart near your heart.

Writing novels preserves you in a state of innocence, a lot passes you by, simply because your attention is otherwise diverted.

I think pop music is in such an exciting place right now, and I do kind of credit that to Lorde with 'Royals.' I think that song changed everything in the pop scene. All of the sudden, alternative pop music became pop music.
