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.

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.

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.

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 suppose that is my central obsession. What we owe to society, what we owe to ourselves.

I come from not just a household but a country where the finesse of language, well-balanced sentence, structure, syntax, these things are driven into us, and my parents, bless them, are great custodians of the English language.

For me, writing has always come out of living a fairly to-the-bone kind of life, just really being present to a lot of life. The writing has been really a byproduct of that.

It's better to dance like a fool, than to stand around like an idiot.

I just had a baby. I'm not going to work unless it's something really special and meaningful, because I can't imagine missing all that time with my daughter.

Life is intrinsically, well, boring and dangerous at the same time. At any given moment the floor may open up. Of course, it almost never does; that's what makes it so boring.

I've been saying I really want to get a 1992 Jeep Sahara, and I'm going to paint it so it looks like the 'Jurassic Park' Jeep. I've actually seen a guy who did have a Jeep Sahara, and he did make it look like the 'Jurassic Park' Jeep. I gave him a thumbs up and said, 'You're awesome!'

The more grateful I am, the more beauty I see.

Gods plan makes you sing about resurrection when your hanging on a cross.

A young man is so strong so mad so certain and so lost. He has everything and he is able to use nothing.

Not missing games, miss one game due to injury in my career, and that even hurt me to miss that game, but I just love to get out there and compete, both ends of the ball, and I don't think I'm afraid to take the big shot. If I'm 2-for-15, I'm not afraid to take that shot, make it 3-for-16.

We do not need $1 allowed for the president to enact amnesty.

George H.W. Bush assembled a 'coalition of the willing.' We need to do that again.

Every time there's a revolution, it comes from somebody reading a book about revolution. David Walker wrote a book and Nat Turner did his thing.

Parentage is a very important profession, but no test of fitness for it is ever imposed in the interest of the children.

What's the difference between my wife and a terrorist? You can negotiate with a terrorist.

Man is subject to innumerable pains and sorrows by the very condition of humanity, and yet, as if nature had not sown evils enough in life, we are continually adding grief to grief and aggravating the common calamity by our cruel treatment of one another.

How unbearable at times are people who are happy, people for whom everything works out.

I sort of don't believe in closure. In the sense that it doesn't make me feel better to think that something is over.

I wished upon a star, hoping it come true. The next day we met and I ended up with you.

Poverty-fighting programs are not handouts - they are investments.

The dumber half of the audience - whether they're male or female, and a lot of them are male - for some reason responds very quickly to the feminine voice. How can I put it? They kind of instantly react to the female voice in a positive way quicker than they would the male voice.

I keep three framed photographs on my desk: the latest school picture of my daughter; a photo of my wife getting her diploma from the University of Chicago; and Lytton Strachey, looking serenely self-possessed.

There was enough tension in the room to send a fleet of the nervous running for their tranquilizers.
