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.

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.

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.

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.

The most dangerous enemy in the world is the one you do not recognize.

There's doubt in trying. Just do it or stop thinking.

Doing the right thing for someone else occasionally means doing something that feels wrong to you.

Instead of abandoning competition and giving banks protected monopolies once again, the public would be better served by making it easier to close banks when they get into trouble. Instead of making banking boring, let us make it a normal industry, susceptible to destruction in the face of creativity.

It's an actor's job to play all the human conditions - light, dark, and medium.

Sometimes, as actors, we feel like we want to hold on and control where a character goes.

The pro-immigration people are really having a fit saying that I don't care about the children.

Secular humanists can sit around and talk about their love of humanity, but it doesn't stack up against a two-millennium-old funeral high mass.

I feel really lucky. My fans are incredibly loyal. They encourage me to keep going. I feel more torn, trying to fulfill what my kids need. It's really huge. They're doing so well.

Every time you think the problem is 'out there,' that very thought is the problem.

Comic-Con has become more of a pop cultural festival, and to not be included feels like you're missing the biggest celebration of the year.

I have a lot of stuff I want to talk about and offer up. It would be odd not to have ideas about something.

Whenever I did a good performance, my Dad and my uncles, who were rabid movie fans, took me to the movies. There began my underlying love affair with film.

I am responsible for me. I can kind of take care of what I need to do and should do what I like to do.

Hip-hop has done so much for racial relations, and I don't think it's given the proper credit. It has changed America immensely. I'm going to make a very bold statement: Hip-hop has done more than any leader, politician, or anyone to improve race relations.

I'm a fun-loving guy. We are basically from Amritsar and ours is a chilled-out family. I think I have got my humour from my mother.

Simply stated, testimony-real testimony, born of the Spirit and confirmed by the Holy Ghost-changes lives. It changes how you think and what you do. It changes what you say. It affects every priority you set and every choice you make.

If you want to ask about my drug problem, go ask my big, fat, smart, ten pound daughter, she'll answer any questions you have about it.

In art religion and politics the respect must be mutual no matter how violent the disagreement.

Impact lies in the vicinity of mistakes.

That was the toughest thing I ever had to do: tell my son that his mum was gone. I was a bachelor living on the beach, but I had to pull it together very quick for my boy.

I can't wait to work with Peter Capaldi as the next 'Doctor.' I know him from old; he's such a lovely man and will be brilliant in the role. As long as he tones down the Malcolm Tucker swearing.
