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.

I am not saying I am the best manager in the world. But I'm quite good.

When I came to America in the '60s, it was the place to be. I wonder if I'd come here today.

The true teacher defends his pupils against his own personal influence. He inspires self-distrust. He guides their eyes from himself to the spirit that quickens him. He will have no disciple.

All my fiction starts from a feeling of unique perception, the pressure of a secret, a story that needs to be told.

I didn't know how to kill off a character unless I was able, as a narrator, to get really complicated. Because it was a big deal. I'd never killed a character before.

Women have helped shape our world, yet still do not receive the recognition and compensation they deserve.

I thank my personal staff for their restless sacrifice for my work.

Couture has copied my things for years, in addition to countless other costume designers, claiming theirs were the original ideas. It's all part of the business, unfortunately.

When you're doing Sebring in the back straight at 185 or 187, and the car's moving, you gotta know what to do with it, how to read it. Just the science of understanding shocks - forget spring rates - is mind-boggling.

Animals in general have always been my passion, project, crusade - whatever you want to call it! The ocean is such a huge, beautiful thing that I feel like we all take for granted.

I'm hard of hearing. I miss a lot. It's really tough.

I've always been a gurner. I tried to reel it in. You know there was a period when I thought I was going to be a really serious actress, but the gurning... I can't get in control of it. It just runs away with me.

After 40, your chances of getting pregnant are between two and eight percent, and in my particular case, they were less than five percent.

We can't equate democracy with Christianity because the largest democracy on earth is India, which is primarily Hindu. The third largest democracy is Indonesia, which is Islamic. Democracy and freedom are not dependent on Christian beliefs.

Continuous as the stars that shine / And twinkle on the milky way, / They stretch'd in never-ending line / Along the margin of a bay: Ten thousand saw I at a glance / Tossing their heads in sprightly dance.

One lesson I got from Gandhi, 'Be the change you want to see,' haunts me. I just feel like I can't keep stomping around pointing the finger at BP when I am supporting the oil industry with my very own dollars and actions by buying their products, helping to pay their mortgage - plastic is from oil... polyester, shower curtains.

If you want to be in the world I live in, which is a creative world with new ideas, then you've got to get away from the norm. You've got to go for it.

We owe our troops more than rhetoric; we owe them a real plan. The Administration has yet to put forward a strategy for achieving stability in Iraq, ending the conflict, and handing over sovereignty to the people of Iraq and the new Iraqi government.

I have a characteristic since my childhood. I don't like living together with my mother, sister, or friends at my home. I have always preferred to be alone and independent and lived according to that.

The eye, like a shattered mirror, multiplies the images of sorrow.

Through our CO2 emissions, we are making the earth a more fertile world.

Sometimes when you get to the press conferences, you hear you're going to play this person in the semifinals, and in the quarters, you're going to play her. And I'm like, 'Hold on a second.' First of all, you have to make it there. Second, your opponent needs to make it there. It looks easier on paper than it is in real life.

We started playing the Baltimore Colts early, and I was still very impressed with Johnny Unitas, who just passed away recently. I thought he was one of the best quarterbacks at the time when I was very young, he was in his prime.

I really started considering myself a writer when I was about seven or eight years old. I wrote stories from my dreams and kept them all in a notebook that I still have.
