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.

A strong conviction that something must be done is the parent of many bad measures.

As Cuvier could correctly describe a whole animal by the contemplation of a single bone, so the observer who has thoroughly understood one link in a series of incidents should be able to accurately state all the other ones, both before and after.

There is an outdated belief that girls are not as good at science and math subjects as boys. But according to the report 'Generation STEM,' high school girls earn more math and science credits than boys do, and their GPAs, aggregated across math and science classes, are higher than boys'.

There are so many things from movies that are remembered, that are just looks on people's faces or incredible vistas or beautiful pictures. That is a very important part of cinema.

All my life I had a rapport with black caddies.

A woman doesn't just love a man. She loves who he is. And, who he is is dependent on what he needs.

So, things aren't clicking with this sweet guy who keeps calling you. So what? Things like chemistry and fate and all the rest actually exist. You don't need to flip out if you're seeing a guy who's really nice to you and you're not attracted to him. It doesn't have to necessarily be because he's nice to you and you hate yourself.

Great leaders are willing to sacrifice the numbers to save the people. Poor leaders sacrifice the people to save the numbers.

When I was ten, I loved movies like 'Cool Hand Luke' and 'Roman Holiday.' When I watched those things, I felt like it was such a good escape. It wasn't even that I needed an escape, but I wanted to be an actor so I could give that feeling to someone else.

One meets his destiny often in the road he takes to avoid it.

I had a hard time at Chelsea mainly because I was injured much of the time. Every time I recovered from one injury I seemed to get a new one and it set me back again.

I couldn't be luckier to wake up every morning and be so excited to get to work, even if it's five in the morning.

I love to shop. Clothes, electronics, and I love jewelry, especially yellow gold.

All across Africa, the Pacific and the Americas, we find cultures that didn't know about mouth kissing until their first contact with European explorers. And the attraction was not always immediately apparent. Most considered the act of exchanging saliva revolting.

Well, no one gives aid to Zimbabwe through the Mugabe government.

We had a lion that was living in somebody's basement outside of Branson, Missouri.

You could have the bases loaded, and you bring up the best pinch-hitter in the world to pinch hit, he hits into a double play, and then all of a sudden: 'How could you do that?'

No one cares about you. No one cares. You will die and be forgotten.

A good team needs three things: the right people, the right spirit, and a couple inside jokes.

My parents were really, really cool about supporting what I wanted to do at a really young age. I think I was about 10 when I caught the bug. They would drive me down to New York if there were auditions. When I was 12, I did this show on Broadway called 'High Society,' so we moved to New York for the run of that.

The first bike that I bought was a Triumph 650. I really like the Triumph 650. I mean, of course, I've driven Harleys, and I think in 'Savage Seven' I drove an Indian, but - I really love Triumph.

As long as I have my faith in God, I'm good. I know everything else is going to come.

I've been to many countries and watched a number of conflicts or their residue, and I've served in the military.

There really have only ever been a few people in each generation who step out, are willing to put themselves on the line, and risk everything for their beliefs.
