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

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.

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.

No matter what your mission is, have some notion in your head. Forget the model, whether it's government or nonprofit or profit. Ask yourself the more important question: Is my mission improving the world? Are you sure about it? Seek to disconfirm that all the time. And if you can, change your mission.

Growing up, I was like any Aussie kid - you know we love our sport - that was my favourite subject at school. That is a subject, right?

As winds come whispering lightly from the West, Kissing, not ruffling, the blue deep's serene.

I've done so many independent movies I'm sure no one will ever see, but I've loved the work.

Love thy neighbor - and if he happens to be tall, debonair and devastating, it will be that much easier.

In truththere was only one christian and he died on the cross.

Every man has inside himself a parasitic being who is acting not at all to his advantage.

London style is individual.

Insomnia is my greatest inspiration.

I miss my friends in public school, but it's kind of a part of something that you have to give up. I'd rather perform than go to public school.

You will be a failure, until you impress the subconscious with the conviction you are a success. This is done by making an affirmation which 'clicks.'

If you expect nothing from anybody, you're never disappointed.

The nickel spot, inside. It's the hardest position to play. It's harder than outside.

Most cases, I would say, in a huge amount of cases, countries that have worked with us and have used our financial facilities have come out quick... more quickly and in a better shape from a crisis than would have come out otherwise.

Never give in except to convictions of honor and good sense.

I love the stage - the fact that you only have one take to get it right, the interaction with the audience, and how every show is different even though you're doing the same thing.

Although even when I am being idle I have plenty of food for thought both early and late - thoughts both about and not about art.

There's always gonna be rock n' roll bands, there's always gonna be kids that love rock n' roll records, and there will always be rock n' roll.

I was a class clown. My father was a class clown. My son has been a class clown, and it sort of ran in the family.

I did not dedicate my life to making Baltimore a safer and more just place because it was easy.

Confidence was the backbone of my upbringing. I was an only child, so I was spoilt, loved, and given an enormous amount of confidence by my parents.

To be Jewish is to be specifically identified with a history. And if you're not aware of that when you're a child, the whole tradition is lost.

I don't lecture and I don't grind any axes. I just want to entertain.

There's no story if there isn't some conflict. The memorable things are usually not how pulled together everybody is. I think everybody feels lonely and trapped sometimes. I would think it's more or less the norm.
