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.

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.

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.

If I have a 100 percent batting average, you should fire me, because it means we haven't tried anything really noble.

Saddle your dreams before you ride em.

My family is a kaleidoscope... My family is like that. We're all different colors, like a prism. When we have light shine and stuff, we're beautiful. When it's dark, nothing shines, and it's a rock.

We have to make some movies we have passion for, respect for.

There's a lot of other movies I like, but I don't even pay attention to directors to tell you the truth.

I'm a big fan of Albert Brooks, Nichols and May. I'd like to follow in their footsteps and do comedy films.

The infernal serpent; he it was, whose guile, Stirr'd up with envy and revenge, deceiv'd the mother of mankind.

Christ does not save us by acting a parable of divine love; he acts the parable of divine love by saving us. That is the Christian faith.

Everybody is a political person, whether you say something or you are silent. A political attitude is not whether you go to parliament; it's how you deal with your life, with your surroundings.

Take the time today to be good to you, in thoughts, deeds and actions - but especially in your thoughts.

The work is challenging, interesting and an important part of our legal system.

I am extremely left brain dominant, probably 95%-5%. The feeling side of my brain is not really strong.

I don't care much about hardware. Nintendo games are some of the best games in the world, and from a more graphical standpoint, the Wii can't do what a PS3 or 360 can do.

I don't read books regularly, because I'm always writing them. I've written 30 books, thousands of pages.

Dick Van Dyke spent most of his time setting everybody else up.

What we've got to do is keep hope alive. Because without it we'll sink.

If there is a small rocket on top of a big one, and if the big one is jettisoned and the small one is ignited, then their speeds are added.

My favorite moment of the whole thing was when John Belushi suggested that I get a hold of all the blues records I could so I could research the music.

'Monday Night Football' has the good and the bad points. The bad point is you have to wait around all day, and it disrupts your schedule for the next week. Now you have one less day to prepare for the following week.

Americans use the word 'dream' as often as psychoanalysts do.

It got very tedious saying the same jokes in the same way with the same attitude.

All wars are civil wars because all men are brothers... Each one owes infinitely more to the human race than to the particular country in which he was born.

Stop being a critic and be a light; don't be a judge, be a model. I think we are far too critical. I think the best way to correct behavior is to accentuate and affirm positive behavior and to ignore negative behavior. Generally speaking, there is a time to correct, of course; but my biggest advice would be, 'Affirm your child.'

Let us now peruse our ancient authors, for out of the old fields must come the new corn.
