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.

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.

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.

Nobility of spirit has more to do with simplicity than ostentation, wisdom rather than wealth, commitment rather than ambition.

I'd say I watch a fair amount of TV, but I'm not a TV addict by any means.

The first education to be a good chemist is to do well in high school science courses. Then, you go to college to really become a chemist. You want to take science and math. Those are the main things.

Apologies require taking full responsibility. No half-truths, no partial admissions, no rationalizations, no finger pointing, and no justifications belong in any apology.

I don't want to create a too-big-to-fail player.

We're used to boy meets girl, boy likes girl, instant attraction on TV. But you throw a son in there, you throw a marriage in there, and you've got some really good character stuff.

New York has more hermits than will be found in all the forests, mountains and deserts of the United States.

Everyone's attention span is getting shorter. As a result, everything - films, music, art - gets watered down and dumber. Every now and again, you get something great, but not often.

I love to dance, and sing - in the shower, not in public. I'm too old to go raving, but my fondest memories are of that kind of thing - dancing, with lots of people, outside if possible.

A lot of directors idealize their leading ladies or turn them into these objects of sexuality and beauty.

Sometimes the nature of a big movie, the nature of the material, the scene doesn't have the richness that you'd want it to.

I think it was a good thing that Joanie and Chachi married.

The funny thing about making this record and being away from the girls and on my own in LA is that it allowed me to reflect on how much we've accomplished.

I like my life alone. I mean, I love being with friends, and I love kissing and loving someone to pieces. But it's hard to find someone who doesn't ultimately start judging you and your choices.

'Arctic Summer,' as you might know, is the title of Forster's one unfinished novel.

Today, if you have an Internet connection, you have at your fingertips an amount of information previously available only to those with access to the world's greatest libraries - indeed, in most respects what is available through the Internet dwarfs those libraries, and it is incomparably easier to find what you need.

One thing I have been banging on about, we have a dessert deficit in the U.K. We still import a very large proportion of our desserts. I would ask everyone to go out and buy a British dessert.

I think I'm as good if not better than everyone else.

I'd like to have a decade of my life back. I dropped into a void for almost a decade.

Me and Matt love to argue, but in general our sense of humor is pretty much alike.

Fame - a few words upon a tombstone, and the truth of those not to be depended on.

In this world, shipmates, sin that pays its way can travel freely, and without passport; whereas Virtue, if a pauper, is stopped at all frontiers.

If you're a lead actor, people are just waiting to say 'you're too old' or 'you're too unhip.' If you're a supporting actor, you can just work forever.

We've had crooks from the beginning of time... it's always very interesting and troubling why good people do bad things.
