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.

It is a bad plan that admits of no modification.

It should consist of short, sharply focused sentences, each of which is a whole scene in itself.

We view things not only from different sides, but with different eyes; we have no wish to find them alike.

Home is where you can say anything you please because nobody pays any attention to you anyway.

Instead of holding on to the Biblical view that we are made in the image of God, we come to realize that we are made in the image of the monkey.

It seems like people are more likely to tell you you've gotten too thin than to tell you you've gotten too fat.

What I do is very theoretical. It won't necessarily have implications for anything anyone is doing tomorrow, yet you know that there's a sense of progress in science, and as we understand more, it just turns out that, somehow, the world evolves with us.

I'm not interested in how people dress.

As soon as you think you know someone else's truth better than they do, you are in deep water.

The most famous Obama precept is, 'No drama.'

Pastoral theology and care helps people look deeper at the intersection between their inherited religious traditions and their current life situations.

From 1989 to 2000, I was focusing in on my children. I hadn't realized the world had changed a lot. AIDS had happened, for starters, and so many people in the arts died or were affected.

I was so in love with the idea of making people laugh for a living that I didn't care what I had to do to get there. Or how much money I was going to make when I did get there.

Every human being is called to solidarity in a world battling between life and death.

From what I've understood, it's an entirely different world, and it's a tough world to get your foot in the door, but I've always wanted to be a voice of a Disney character.

All we ask is that we have peace with the whites. We want to hold you by the hand. You are our father.

I am not here to accuse the media of anything.

History must give the Poles the principal credit for bringing the Soviet bloc to its knees.

I fed them every day. So it was a papa that kept food on the table for them. I did that. I did my part.

In ordinary life we hardly realize that we receive a great deal more than we give, and that it is only with gratitude that life becomes rich.

Howard University shocked me into realizing how desperately sick the Negro could be, how he could be led into self-destruction, and how he would not realize that it was the society that had forced him into a great sickness.

Artists don't really want to be marginalized. They believe that everybody should be able to appreciate the experience that an artist gives them, an experience that connects us to each other in a deep way.

Sometimes the smallest step in the right direction can be the biggest step of your life.

Some things are worth the splurge.
