During the two to three hours right before bed, avoid viewing bright screens.

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.

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.

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.

Everything that's supposedly caused by stress, I tell people there's a Nobel Prize there if you find out the real cause.

All work and no play make any forensic pathologist a dull boy.

Every hero must return home. Starks to Winterfell. Harry to Privet Drive. Luke Skywalker to Tattoine. Katniss to District twelve. The fun is in seeing how they return.

Dear mind please stop thinking so much at night I need to sleep.

That was never on my radar, traffic stopping. It was never important to me.

When I get it into my head that I want to do something, I do it.

In science, the credit goes to the man who convinces the world, not to whom the idea first occurs.

Dwelling on the past only blinds you to the future.

For most men life is a search for the proper manila envelope in which to get themselves filed.

I tend not to trust people who live in very tidy houses. I know that on the surface there is nothing wrong with a person being well-ordered and disciplined. Nothing, except that it leaves the impression of that person having lived in the confines of a stark institution which, although he or she has long since left, remains within.

Hungary has no raw materials and no major energy sources; we have some agricultural background. So what we produce here in Hungary is the result of our labor and minds, and then we have to sell it to the world. If we are not able to do that, if we are not innovative enough, if we are not modern and open enough, we can't do that.

There is always that thought that you might get stuck with a character. But there's always the notion that every character is always evolving.

My pop did a little time.

When you are as great as I am it is hard to be humble.

Loyalty is a fine quality, but in excess it fills political graveyards.

From the beginning... I wanted to build a company that could sustain not for two years or four years or even ten years but be something that really matters over time the way Amazon and Google and others have.

I always have to have mascara; otherwise, I feel like I don't look awake enough. It's like, 'I have eyes now!'

The ego is an illusion. The more we submit to its cravings the more unhappy we become.

The true basis of morality is utility; that is, the adaptation of our actions to the promotion of the general welfare and happiness; the endeavour so to rule our lives that we may serve and bless mankind.

In the streets the children screamed. The lovers cried, and the poets dreamed

Class or the economic status of individuals is evident in all societies some very well stratified by a rigid caste system determined by birth.

I was endorsed by many corporations to work with their people. Since I had several hundred successful case histories, I realized that it was really valuable and everybody should have access to the information, so I started teaching seminars to groups of people.

If I don't ask for something, I'm not going to get it.

I feel like when you do things with such a small budget, it actually makes you be more creative... and allows you to concentrate more on the story and the characters. I think that there is something about dirty, gritty and raw filmmaking that makes it feel a little more natural and makes it easier to connect with the action.
