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.

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.

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.

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.

I was always accused of being too stiff. In 1974, when I ran my first primary race for state rep, I was chief aide to the speaker of the House, I knew the issues and understood state government. But what I found out the hard way is that you can know all the ins and outs but people want to know you, your family.

Charity creates a multitude of sins.

Growing up, my mother and grandparents often talked about our family's Native American heritage. As a kid, I never thought to ask them for documentation - what kid would?

I like to work. The self-esteem and satisfaction that I get from working makes me a better person, which makes me a better mom. I feel lucky because I have the luxury of working only one or two days a week.

I am Jose Mourinho and I don't change. I arrive with all my qualities and my defects.

When I'm on a strict eating regimen, at some point I have to have French fries, a cheeseburger and some pizza. And Oreos and vanilla ice cream!

I had many moments of disappointment, despondency, and exhaustion, but I always found that by reading the literature and showing up at my lab looking at the data as they emerged day by day and discussing them with my students and postdoctoral fellows, I would gain a notion of what to do next.

I challenge all of you to fight for this country.

The weaker the data available upon which to base one's conclusion, the greater the precision which should be quoted in order to give the data authenticity.

When you file an amicus brief, and you represent a state, the court reads your brief. It is a powerful position to make the legal assault from.

To live is to choose. But to choose well, you must know who you are and what you stand for, where you want to go and why you want to get there.

After two world wars, the collapse of fascism, nazism, communism and colonialism and the end of the cold war, humanity has entered a new phase of its history.

Existence is not a mystery unless you think it has a meaning.

I love going into the studio with just an idea of the direction. Like, I want this tempo... I love to start from scratch, and the tracks sort of take on a life of their own.

Kid, you’ll move mountains!

I learned how to deal with people with elegance from Patrick Swayze.

If they can see you love them, you can say anything to them.

The nakedness of the indigent world may be clothed from the trimmings of the vain.

?Life is a shipwreck, but we must not forget to sing in the lifeboats.

I hope my desire to travel so much isn't forever because it's not the most conducive lifestyle for a relationship or a family by any means.

Fertile soil, level plains, easy passage across the mountains, coal, iron, and other metals imbedded in the rocks, and a stimulating climate, all shower their blessings upon man.

We should be writing more great roles for women, period. Another problem is that movies are generally made for 14-year-old boys, and 14-year-old boys want to watch 25-year-old action heroes.

Stand-up can take you in so many different places, man. So many doors can be opened up from stand-up comedy, and the first one that was opened up for me was acting.

Obviously, a long-distance relationship is hard. But, like anything worth having, you make it work.
