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.

Few are there that will leave the secure seclusion of the scholar's life, the peaceful walks of literature and learning, to stand out a target for the criticism of unkind and hostile minds.

Baptism is not the work of man but of Christ and this sacrament is so holy that it would not be defiled even if the minister were a murderer.

Dover's cliffs call to mind the Roman invasion; the Battle of Britain; our proximity to, yet difference from, mainland Europe; and international trade and exploration, both fair and exploitative.

I'd always thought hurricanes were romantic, with pretty feminine names like Celestine.

I don't think about the styles. I write whatever comes out and I use whatever kind of instrumentation works for those songs.

When you watch someone on TV go through something that you're going through that's difficult, it lets you know that you're not alone, and there's nothing to be ashamed of.

You can't run a business just by selling one thing.

I'm doing a very funny show in which we talk about issues. I speak at Aids charities and things. It's great to do something fun with our days and yet we're told we're doing something important.

Kids kill a show! It's, like, a fun concept when the character is pregnant, but then if a show runs for a while, I'm sorry, but it gets annoying when it starts to talk. You get a child actor in there, and unless that child actor is freakin' awesome, it's going to be annoying.

Doing something that warrants the attention of the President of the United States is super cool.

Those who closely watched the campaign should not be surprised by Obama's hostility toward Israel, given his relations with pro-Palestinian, virulent critics of Israel and his voluntary membership in Reverend Wright's decidedly anti-Semitic church. Furthermore, his campaign website featured anti-Semitic posts.

I'd love to do drama if it was interesting.

Let's shut down the EPA.

Growing up, I had a very normal relationship with my brother and sister. But, over time, they became my best friends, and now I hang out with them all the time. I'm very close with them.

I liked the structure of ballet.

The thing about sports movies is, they can't help but feel epic - putting music to images, etc.

I was never a bright student, potentially never good at dramatics; I was sometimes given one-line roles that I was happy to do so that I could bunk classes. My mother used to cry three times a year, and that is when my report card used to come.

I'd love to make a thriller.

I want to be there for the last note of 'Freebird' when that happens.

I've worked with a couple of female directors now, and I think that they're amazing. As good or better than guy directors.

My mother made a choice. And when I was younger, I judged her for making that choice. Then I got older and got to be an adult, and I realized that was the ultimate sacrifice that any parent and any mother could possibly make.

There's nothing that can replace the feeling of winning.

I know that I have a voice and can use it for good or bad. It's a gift from God.

I felt like I was a teacher. But nowadays, I am as much a student of his. He writes a lot of what we play.
