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.

Everyone's parents were famous actors at my school, pretty much! I think I went to school with Paris Hilton when I was three. That's what L.A. is, though - it's an industry town. You go to school with kids and you think, 'Well that's normal, they make movies.'

I think that we should be eternally vigilant against attempts to check the expression of opinions that we loathe and believe to be fraught with death, unless they so imminently threaten immediate interference with the lawful and pressing purposes of the law that an immediate check is required to save the country.

Japan continues to work closely with the United States on the issue of the North Korean nuclear crisis and has played an important and constructive role in the Six-Party talks.

It's so crazy to meet people you've known about since you were many feet shorter than you are now.

I once set myself a deadline: half a chapter a week, 20 minutes a day. The thought froze me instantly, like literary Botox. I returned to my non-schedule: sleeping, writing 20 minutes, and then back to sleep. Breakfast in bed, with juice congealing on the sill: pages and pages began to pour out again.

When I grew up in India, telephones were a rarity. In fact, they were so rare that elected members of Parliament had the right to allocate 15 telephone lines as a favor to those they deemed worthy. If you were lucky enough to be a wealthy businessman or an influential journalist, or a doctor or something, you might have a telephone.

My children have absolutely no interest in my fame. They're very sophisticated, and they have a spiritual perspective on material things because we go to church.

The single most important thing a city can do is provide a community where interesting smart people want to live with their families.

You get to a point where the kind of beautiful chaos can't really fuel your creative existence any longer because it's not stable, however amazing and exciting it may be.

And a third thing is the understanding of the Church as a community, a communion which is just a hierarchy but the people of God, whose servants are the priests and bishops.

Any idealism is a proper subject for art.

Having children is fab. They keep me young and make me get up in the morning.

If there's one thing that makes me cynical, it's optimists. They are just far too cynical about cynicism. If only they could see that cynics can be happy, constructive, even fun to hang out with, they might learn a thing or two.

Life will always throw you curves just keep fouling them off. The right pitch will come but when it does be prepared to run the bases.

For me, it is just the total experience - from the time I first started as an assistant coach until I wound up at the University of Texas for 20 years.

My first western was 'Death Hunt' with Charles Bronson and Lee Marvin; that was where I learned to ride. The movie was based on a true story about a guy that eluded the Mounties in Canada. We were in Canada for six weeks riding horses.

My mom taught me to live by the three p's: to always be passionate, persistent, and prepared.

I get a little too obsessive with work.

I am pleased to see that many of the world's leaders have publicly recognized that the crisis in the Middle East was deliberately incited by terrorist organizations.

If we had a consensus we wouldn't have to go to a referendum.

I think we're all a lot more like our parents than we want to admit.

If all opposition were curtailed, if all maladies were removed, then the primary purposes of the Father's plan would be frustrated.

Climbing, for me, is all about solving the magnitude of the problem. The best projects are the ones with big question marks hanging over them.

I wanted to start with a very small role, to get my feet wet. I'm sure I'm not as good or as experienced as other actresses, but everybody has to start somewhere.
