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.

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.

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.

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.

Do what is best for most people, not just a few. Prevent your elites and growing middle class, those who often benefit most from growth and development, from turning into a special interests group that blocks reforms.

I went to the premiere of The Detective with Sinatra, and perhaps people jumped to conclusions. He was very protective towards me and never came on to me sexually.

God exists in eternity. The only point where eternity meets time is in the present. The present is the only time there is.

There's just a feeling you get from certain things you do in life that just kind of feel pure and independent of what's actually, physically, going on.

YouTube and other sites will bring together all the diverse media which matters to you, from videos of family and friends to news, music, sports, cooking and much, much more.

Sober Driving Today. Alive Tomorrow.

I was unwise enough to actually mention this in public a few times, and in fact to point out that there were two versions of the book now. One of them had somebody else's name on the cover, one had my name on the cover.

I can assure you we are a responsible nuclear power.

It's a tender and complicated dance, watching our parents age. We become protective in ways we never were before, and we study them with a mix of sadness and curiosity: Is this what we will be like when we are their age? We tell ourselves to be patient - just answer the same question again as if it wasn't answered a moment ago.

The connections in the brain fade away unless used. We know that early stimulation of children leads to higher cognitive scores.

The reason fat people are happy is that their nerves are well protected.

I would fly to Los Angeles just for a cheeseburger with pickles and extra tomatoes from In-N-Out.

Pray that your loneliness may spur you into finding something to live for great enough to die for.

I'm from the old school - you go where the power is, and you try to make fun of it. When it becomes off limits to say or do certain things without being brutalized or censored or whatever, it's unfortunate.

A single act of kindness throws out roots in all directions and the roots spring up and make new trees.

The mental capacity of a person to make reasonable contracts, is the only criterion, by which to determine his legal capacity to make obligatory contracts. And his mental capacity to make reasonable contracts is certainly not to be determined by the fact that he is, or is not, twenty-one years of age.

For many women, going back to work a few months after having a baby is overwhelming and unmanageable. As strange as it may seem, things get even more difficult for a working mom after the second and third baby arrive. By that time, the romance of being a modern 'superwoman' wears off and reality sets in.

When I get the record, all it will make me is the player with the most hits. I'm also the player with the most at bats and the most outs. I never said I was a greater player than Cobb.

What I like about South Florida is there's a good quality of life here; the cost of living is much lower than Silicon Valley.

Berta Caceres, a Lenca woman, grew up during the violence that swept through Central America in the 1980s. Her mother, a midwife and social activist, took in and cared for refugees from El Salvador, teaching her young children the value of standing up for disenfranchised people.

Circumstances dictate your set of values, your set of morals.

Authors are ordinary people who usually start to live apart, in the imagination, because they don't fit in with normal, healthy people.

The sensory acts are accordingly distinguished by their objects.

I don't write historical novels but novels that wonder, 'And what if it happened in this way and not in this other one?'
