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.

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.

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.

Because my life has been so notorious and so bad, it can overshadow my work.

You have to show violence the way it is. If you don't show it realistically, then that's immoral and harmful. If you don't upset people, then that's obscenity.

I've made my share of mistakes, but had the good fortune to have them not be so public.

Morning not only forgives, it forgets.

The heavy guitars are the ones that sound good. They are not that comfortable but they do sound great.

We're dealing with sophisticated customers. What's most important to these women is individuality. I have to create things she'll want to wear, no matter who she is.

As soon as I know how to do something, I usually get bored with it.

I just want to be in the studio 24/7. Even if I'm not working on a song right then, just sit in the studio. That's what I love.

People often express surprise that I'm not a psychopath. But it's not about what I want to do to other people, it's that I'm scared of what other people might do to me.

I think it's very comforting for people to put me in a box. 'Oh, she's a fluffy girlie girl who likes clothes and cupcakes. Oh, but wait, she is spending her weekends doing hardware electronics.'

Where there is a monster, there is a miracle.

I was a naughty kid. Teachers did not like me much.

The EU should be concentrated on adapting to globalisation and global competitiveness, not building more powerful centralised institutions in Brussels.

I liked Columbia, but it was like high school in that there was this big social world that I was not part of. I existed on the side, far away. That might be temperamental, my own fear of large groups, more than anything else. But I had a handful of professors who meant a lot to me.

Who told you you're allowed to rain on my parade?

Life is defined by the lives you touch, and not by the mistakes you've made.

There's probably people that go to Harvard and say, 'Listen, I went to Harvard. I got a great education, and I can't find a job, or I didn't become the success that I could have been.' Sure, I mean, you probably have that at every major university.

If something makes me happy, I go with it. It's as simple as that.

I give away thousands of paintings for free.

Life is tough in Mumbai when you are alone.

If you hit a Talib with your shoe, then there would be no difference between you and the Talib. You must not treat others with cruelty and that much harshly, you must fight others but through peace and through dialogue and through education.

Why do we have to have violence, torture, brutality in crime dramas every time we turn on television? Any new crime drama is going to have, sooner or later, a lot of torture and nasty things that make people flinch. Lots of young people I know shrink and flinch from that kind of thing on television, so I think showing it is a mistake.

The idea that seeing life means going from place to place and doing a great variety of obvious things is an illusion natural to dull minds.

Reacting in anger or annoyance will not advance one's ability to persuade.
