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.

I don't own everything, I do have a partner.

Don't be distracted by criticism. Remember - the only taste of success some people get is to take a bite out of you.

The people who believe themselves to be on the left, and who defend the agents of Islam in the name of tolerance and culture, are being rightwing. Not just rightwing. Extreme rightwing. I don't understand how you can be so upset about the Christian right and just ignore the Islamic right. I'm talking about equality.

I went camping one time when I was twelve, to the Great Lakes. My friend stepped in really deep muddy water and started screaming and sinking. My mom ran up, and I was just standing there a foot away and wouldn't stick out my hand to pull him up. So I'm probably not the best person to take on a camping trip.

I think now, we in the international community are belatedly wanting to show our solidarity with the Somali peoples and also do our best to help them move to better times.

I fought for seven years to have creche facilities at the Okinawa Institute of Science of Technology - and was ultimately successful. Less successful have been efforts to get a creche at the new Crick Institute in London, but this is something I will continue to push for.

I kept turning down roles because I knew I just wasn't ready for them.

I'd worked at the White House for two years, and I'd read a bunch of White House memoirs because everybody who works at the White House, even for five minutes, writes a memoir usually not less than 600 pages long - and never without the word 'power' in the title.

I went to Rikers one time to do 'Third Watch,' and I remember thinking, 'Wow, this is a scary place.' We were using a section of the prison where half of it was still populated by inmates.

I wouldn't want a tattoo at all. They're difficult to cover up.

I call my life a beautiful mess and organised chaos. It's just always been like that. My entire life things have been attracted to me and vice versa that turn into chaotic nightmares or I create the chaos myself.

Life is now a constant assessment of whether what's happening in real life is more entertaining than what's happening on my phone.

I believe in a strong national defense. But it's my belief that neither Iraq nor Afghanistan poses a threat to national security, and we shouldn't be involved in either area.

To one who believes that really good industrial conditions are the hope for a machine civilization, nothing is more heartening than to watch conference methods and education replacing police methods.

What some people interpret as brooding melancholy is serenity. I don't feel required to grasp all the time.

Aaron Copland was a man that had a very specific point of view about what music should be which was that, he felt that new music should have the composer should show a personality in his music.

My views are just about the same as Casey's.

Destiny is something not be to desired and not to be avoided. a mystery not contrary to reason, for it implies that the world, and the course of human history, have meaning.

Do your best one shot at a time and then move on. Remember that golf is just a game.

She's a different kind of BFF. One who is a little younger, and finds you so cool just because you care and have grown-up clothes in your closet. As she gets older, you might become her shoulder to cry on, but right now, you have so many smiles and snacks you need to share.

Love is all we have, the only way that each can help the other.

A car designer is really a sculptor.

My life hasn't been conventional and it hasn't been linear. I've had to make it up as I've gone along, which has taught me a lot. If you don't accept the obvious options that are laid out for you, it's up to you to work out where you're going and to create your own specific rules and goals.

I like what L'Oreal stands for, which is women of worth.
