During the two to three hours right before bed, avoid viewing bright screens.

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.

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.

Happiness is seeing the muscular lifeguard all the girls were admiring leave the beach hand in hand with another muscular lifeguard.

Well, I wouldn't say that I was in the great class, but I had a great time while I was trying to be great.

It takes a big heart to help shape little minds.

I never felt I had questions or needed answers or had a part of me that was missing.

Lawyers are the foot soldiers of our Constitution.

Long hair will make thee look dreafully to thine enemies and manly to thy friends it is in peace an ornament in war a strong helmet it... deadens the leade thump of a bullet in winter it is a warm nightcap in summer a cooling fan of feathers.

It's easier for me to go to Russia and train with top coaches and choreographers there than go to Colorado Springs and train with 14 of my competitors.

They continued but six days under this course, having consumed the quantities that could be spared.

My mother is brilliant; she's the best person in the world and keeps me grounded.

When you're a musician and you break new ground it resonates into the common consciousness.

Julian Assange is certainly no hero. The man behind WikiLeaks issued threats as if he were Dr. No bent on ending civilization as we know it. We will find him, lock him up, and throw away the key. But give the man credit; for a week the truth was laid bare.

It was impossible for Hillary Clinton to have chosen a path to the White House that bypassed the loathing, jeering derision and gendered stereotyping built on two centuries of male power. What was interesting was how hard she tried to do just that.

The life of a boxer is about fighting for world titles.

The universe is big, its vast and complicated, and ridiculous. And sometimes, very rarely, impossible things just happen and we call them miracles. And that's the theory. Nine hundred years, never seen one yet, but this would do me.

You must have goals for your life. Do not fear take a bold step to realize your goals.

Space in general gave us GPS - that's not specifically NASA, but it's investments in space.

If, at the end of the day, I can look back and see pictures of all the characters I've played, and there's a smorgasbord of weirdos and interesting, odd, different characters, I'd be so happy.

A smile is happiness youll find right under your nose.

Politeness is the art of choosing among ones real thoughts.

I could cut my leg of; I could cut my arm off. I could gouge my eye out - I'd still probably survive, but not very well, and that's what we're doing to the ocean. It's the life support system of this planet. We've been dumping in it, we've been polluting it, we've been destroying it for decades, and we're essentially maiming ourselves.

It's easy to write a good column if you've got good information. It's hard if you have to depend on style alone. I suppose there are people who can get away with styling on a regular basis. I'm not one of them. You're probably not, either.

I'm a rather crude cook.

I'm not an admirer of action movies. I just think, Oh my God, it must be so tiring.

I do love singing. I wouldn't say I'm any good, but I definitely love it - especially jazz singing.
