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.

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.

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.

Frankly, I'm not sure how far I would get if I attended public school today. It's not just that public schools aren't producing the results we want - it's that we're not giving them what they need to help students achieve at high levels. K-12 education in the United States is deeply antiquated.

While you're going through this process of trying to find the satisfaction in your work, pretend you feel satisfied. Tell yourself you had a good day. Walk through the corridors with a smile rather than a scowl. Your positive energy will radiate. If you act like you're having fun, you'll find you are having fun.

Being at NDSU and winning national championships, everyone's gunning for you. You got a big target on your back, and we had to be ready to go week in and week out. I think playing for a program like that, everyone's going to give you their best shot, and we embrace that.

Digital media are biased toward replication and storage. Our digital photos practically upload and post themselves on Facebook, and our most deleted e-mails tend to resurface when we least expect it. Yes, everything you do in the digital realm may as well be broadcast on prime-time television and chiseled on the side of the Parthenon.

I grew up in a somewhat religious family. My dad's family isn't religious at all, but my mom's side of the family is, so I was exposed to church a bit.

I am a public person and I have my private life. It's important for me that my private life stay private, that what I share with the people is my public personality.

Me and Matt love to argue, but in general our sense of humor is pretty much alike.

I suspect that American workers have come to lack a work ethic. They do not live by the sweat of their brow.

I think you'd have to literally live in a cave to not know anything about 'Twilight'. I've seen a few of the movies, but I haven't read the books.

The chief part of a persons happiness consists of pleasure

Once this key conflict is eased, it will have a huge impact on the world. It will take time to find a solution. It's similar to the situation between East and the West at the time of my flight.

You ever get that feeling that you just have too many hits?

I write about real people in disguise. If anything, my characters are toned down-the truth is much more bizarre.

It is criminal to put our servicemen and women in harm's way and to put the lives of so many civilians on the line for the misguided frustrations of the Bush administration.

We try to live by the secret of sevens. A friend, who has been married for over 40 years, told us about this magic. Make and keep a date every seven days, take a night away alone, for yourself, every seven weeks, and schedule an adult-only vacation every seven months.

Any party that would put Sarah Palin up on a pedestal will never have my support.

There is a form of clean energy renewable and absolutely free that too often underestimate human warmth.

I used to tweet about the most mundane things - like 'I just bought a soya latte' - but now I try and make it a bit more interesting.

I think one of the biggest mistakes that America has made - and maybe the world because this is, sort of, the core of communism and socialism - is that you can have perfect solutions to social problems like poverty, like crime. You're not going to eliminate all crime. Maybe you'll never eliminate all poverty.

I'm a big proponent of monogamous relationships regardless of sexuality, and I'm proud of how the nation is steering toward that.

I cycle, which is a healthy thing for an 80-year-old to do. I rarely go further than five miles, but in those five miles I can get to 80 percent of the places I want to go.

No, I never thought about my father's money as my money.

All my life, whenever it comes time to make a decision, I make it and forget about it.

Suddenly you’re ripped into being alive. And life is pain, and life is suffering, and life is horror, but my god you’re alive and its spectacular.
