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 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 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.

No one believes in love at fisrt sight until that special persons comes along and steals your heart.

The irony is that 'looking down on everybody else' is a violation of the law of love, which, according to Jesus, is the absolute essence of righteousness.

To me you are stardust sprinkled across a night sky, forever in my dreams, but out of my reach.

My limitations are - I'm not Meryl Streep. I'm not playing anything in a foreign language, or anything too far from who I am.

You have to see the human being in the enemy. If there is potential for change, there is still hope.

Most of us will do anything to avoid facing ourselves

We found what we could at that time - the truth. If somebody else can find something else which we didn't find, that, of course, is a duty on their part, as is the truth. It will be the truth.

If we are striving, if we are working, if we are trying, to the best of our ability, to improve day by day, then we are in the line of our duty.

Being aware of the bondage is enough to free you from its clutches.

Katie Couric is one of my favorite people.

You must lose everything in order to gain anything.

I love a straightforward character. I am the guy who loves Cyclops on the 'X-Men', because he is square.

And how can you achieve such concentration? By recognizing that everything you do is important to God, and is one vital piece of the larger picture of your life.

I did not become a vegetarian for my health I did it for the health of the chickens.

The fun of sitting around Pangong Lake with 40 guys around a fireplace, having a glass of wine... staying in one camp together... that's an experience. Waking up at 5 in the morning, watching the sun come up. You don't do these things in Bombay.

Milos said, You're my first choice. From my point of view, that doesn't pay the rent. I said, Tell me what I have to do next because I'm busy painting my kitchen.

Clouds are the skys imagination.

Notoriety wasn't as good as fame, but was heaps better than obscurity.

You just never know what the grand plan is on 'Dexter,' so I didn't know if I was going to make it to the next episode, let alone the next season!

I need to push myself. I'm not saying that I just want to do anything that's shocking, but when you have that combination of a script that's really beautiful and extremely shocking, it's exciting for me.

I started off with violin, then I started learning guitar, then I went to piano. But I self-taught piano just because I enjoyed it. I've always really enjoyed music.

Even if the music industry simply gave away all their music people would complain that they don't have the bandwidth to download all the stuff - the problem would merely shift from availability to distribution.

I have the absolute utmost respect for soap opera actors now. They work harder than any actor I know in any other medium. And they don't get very much approbation for it.

It's nice to have a crush on someone. It feels like you're alive, you know?
