Use computer glasses that have yellow-tinted lenses that increase contrast and help block blue light.

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.

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.

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.

Doing beautiful things is its own reward.

No love, no friendship, can cross the path of our destiny without leaving some mark on it forever.

Jazz is the false liquidation of art, instead of utopia becoming reality it disappears from the picture.

I think what's most fun is playing someone who's sort of selfish and in a lot of ways unlikeable, but there's this really big heart underneath it that you get little glimpses of.

After writing 'The Omnivore's Dilemma,' I wanted to write a book that got past the choir, that got to people who didn't care about how their food was grown but who did care about their health.

We've got to have rules and obey them. After all, we're not savages. We're English, and the English are best at everything.

The only thing I don't have is hips.

You must accept that you might fail; then, if you do your best and still don't win, at least you can be satisfied that you've tried. If you don't accept failure as a possibility, you don't set high goals, you don't branch out, you don't try - you don't take the risk.

Writing, producing and directing, I must say, is incredibly satisfying and gratifying.

I'm comfortable in my miseries. I have no choice.

I am at a crossroads; I have always been against armed opposition... I have chosen civil disobedience. But I will apologize to my people if there are funerals coming out of prisons. I will criticize myself and I won't be the mayor of Diyarbakir.

I love having my hair back. It is so important to how you feel, how you dress, how you look.

I played, like, a year of piano until I learned the 'Pink Panther' theme. That was my goal. Once I was good enough, I quit. Now my music has to have some rock.

It is very hard to win when your thoughts turn to losing.

I don't want the kids to go through want I went through.

Divorce is probably as painful as death.

The London Games will be designed for the athletes and we will provide them with the very best venues and the very best conditions to pursue their sporting dreams in London.

He who loves others is constantly loved by them. He who respects others is constantly respected by them.

I've always kind of lived in my own world.

I hope to continue acquiring companies, not so much for the accumulation of wealth but because it's what I do well, and you always like to do what you do well.

I have said repeatedly that the way to sustainable growth is to bring down inflation to much more reasonable levels.

But then I hit my 20s and only made two albums, and now I live in a ski resort as a ski bum basically.

If I was to direct a movie about a super-confident guy, first of all I would hate that character. I can do a super-confident guy who crashes and burns and has to rebuild himself as somebody humble. But a super-confident guy that just gets more confident and gets the girl and the money and more success? That's not interesting.

We use the people who are in the bullpen producing.
