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.

For the continued survival of our planet and humanity, it is crucial that certain discoveries and skills and inventions made by people over the years be passed on from one human generation to the next, from one person, face-to-face, to another.

The auditioning process is one in which the actor gets very little information about almost every element of it.

A democratic organization has to dare to do the right at all costs.

Yu Na Kim, Mao Asada, Carolina Kostner - all these girls can do triple-triples in their sleep, and they have the skating skills and the spins and the rest of the technical jumps. So I have to have that as well if I want to be able to call myself 'competitive' against them. And when I say 'competitive,' I mean I want to win.

I'd never have a facelift, as I have never seen one that looks good.

One of the major problems with China is that its innovation is largely borrowed technology.

When you've got an extra gear in your head where that's all you do, you've constantly got a little radar up. ... And when something hits that strikes that beeper, hits that radar, it's like my song skills kick right in and go, 'Oh, OK, there's a song in that.' And then I start trying to figure it out.

Because of the womb being a central phenomenon in the feminine body, the whole psychology of woman differs: she is non-aggressive, non-inquiring, non-questioning, non-doubting, because all of those things are part of aggression. She will not take the initiative; she simply waits - and she can wait infinitely.

You have license in front of the camera to do things, feel certain emotions that you don't get to in real life. It can be addicting.

At school, a careers adviser asked me what I wanted to be, and I said 'fashion journalist,' so writing for 'Vogue' has provided me with the opportunity to fulfill a dream.

I love sitting through long things. I mean, 'Gone With the Wind' I will sit through; I love sitting somewhere for four hours, for anything. I love being on a train. I love sitting down for four hours. I think it's the most wonderful thing to be able to sit somewhere and concentrate on something for more than two hours.

You can't remember the plot of the Dr Who movie because it didn't have one, just a lot of plot holes strung together. It did have a lot of flashing lights, though.

Everything to me is about team football, and if we keep winning Super Bowl trophies, I'll be fine.

I am special.

Genius, like humanity, rusts for want of use.

To reach your destination follow the directions of your heart. It knows the way.

The sixty-minute drama form has become very rich.

Grace like water flows to the lowest part.

I paint what cannot be photographed, that which comes from the imagination or from dreams, or from an unconscious drive.

If we keep doing what we're doing, we're going to keep getting what we're getting.

The act of writing surprises me all the time. A miraculous thing happens when you have an idea and you want to convert it into words... and then you start to create a work of art, and that's another miracle, and it remains mysterious to the writer, or to this writer anyway.

I find forgiveness to be really healthy.

No matter what you do, if there's something you're afraid of, you need to break through it.

Sometimes crying or laughing are the only options left, and laughing feels better right now.
