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.

Being yourself is very sexy, you know?

The idea of being a foreign correspondent and wandering the world and witnessing great events, having adventures and covering the activities of world leaders, appealed to me greatly. It was a very glamorous life in those days.

I don't know why people question the academic training of an athlete. Fifty percent of the doctors in this country graduated in the bottom half of their classes.

My character and good name are in my own keeping. Life with disgrace is dreadful. A glorious death is to be envied.

Telecom is a dramatic success in India and our view is, respecting the political process, and respecting the fact that these are sovereign decisions, is that, approaching India as a friend.

I usually start my day when my kids wake up.

I'm married to a white man, and then my daughter came out looking like the whitest white child with blonde hair and blue eyes. And I'm like, 'Omigosh, now what am I going to do?' She has my mom's features and is lighter than my husband. And my boy is browner than I am. Brown eyes and really tan.

The thing is, my dad's always been more of a bookworm; he was interested in more intellectual pursuits, but nobody can escape the passion that football stirs.

Horror, for me, is not defined by the thing that provokes one's fear, but the human being who has contact with it.

When you have really good writing, you're compelled by the actors who are in it, and you may think it's the actors or the design or the filmmaking of it, but then you're like, 'Well, the base is a really rich story that these guys have created.'

Life is the only real counselor; wisdom unfiltered through personal experience does not become a part of the moral tissue.

A clean house will result in peace in the Middle East as well.

The formation of character in young people is educationally a different task from and a prior task to, the discussion of the great, difficult ethical controversies of the day.

Silence is not weakness and decency is not pride.

You know, maybe I was just born in the wrong time, but I love all things romantic. Puffy understands that. For my last birthday, he covered my hotel room floor with rose petals and had flowers and candles all over the room.

I was in my first movie when I was five. I just loved to entertain and put on a show.

Extraordinary rains pretty generally fall after great battles.

In my family, we let our boys have a say in what veggie side they want for dinner that night. We list off a handful of options and get them excited about helping to plan the dinner menu. They're much more inclined to finish their plates when they've helped decide what goes on them.

Every austerity measure that Cameron and George Osborne make is being presented in Scotland as the English starving us.

My mother's side of the family was in the production side of theatre. My grandfather, Jose Vega, was a general manager for Neil Simon shows on Broadway.

I have never been a girlie girl and have always been a boys' girl with an equal amount of friends who were boys and girls.

Now comes the mystery.

We live and die Christ died and lived

When I retired, I was at an in-between age. I wasn't a child anymore, I wasn't really a woman yet, and they weren't really writing scripts for that age.
