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.

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.

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 think it's nice to age gracefully. OK, you lose the youth, a certain stamina and dewy glow, but what you gain on the inside as a human being is wonderful: the wisdom, the acceptance and the peace of mind. It's a fair exchange.

I'd rather laugh - not fuss and fight. You can articulate your point without arguing. When you're arguing constantly, you just need to say, 'You're real cool, but you're not for me.'

I allowed life to give me presents. And everything just sort of happened the way it was supposed to happen. I did not pursue anything. It more or less pursued me.

The causes of youth violence are working parents who put their kids into daycare, the teaching of evolution in the schools, and working mothers who take birth control pills.

My father fell really chronically ill when I was 13 and that's when I phoned up an agent and started to act.

If we have white persons in the March, we are certain to have trouble with the Communists, and it may not be viewed as a true expression of the Negro's protest.

I live my life parallel with my work, and they are both equally important. I'm always amazed how much people talk about celebrity and fame. I don't understand the attraction.

One of the things I like enormously about Bob Weinstein is that that he's the only studio head I have ever known who will change his mind and say he was wrong.

The consumer is the supreme mover of economic order for whom all goods are made and towards whom all economic activity is directed.

It was important for me early on to find the voice of each character and figure out what was unique about them and their individual worldview that I could use for comedy or conflict.

President Ronald Reagan used to speak of the Soviet constitution, and he noted that it purported to grant wonderful rights of all sorts to people. But those rights were empty promises, because that system did not have an independent judiciary to uphold the rule of law and enforce those rights.

I love The Inn at Palmetto Bluff, an Auberge Property in Bluffton, South Carolina. It's a spectacular corner of the world, with massive old trees lined with Spanish moss, and alligators swimming in the river.

A person with a clear purpose will make progress, even on the roughest road. A person with no purpose will make no progress, even on the smoothest road.

I'm somebody who can laugh even at myself. That happens now and again, when I've made a mess of really simple things.

You have to do whatever jobs you can to pay the rent.

I was the kid at six who was like, 'I want to be in a jazz club.' I was never the pop kid, ever. I mean that's not true, I had a couple years where I wanted to be Tiffany and Debbie Gibson, but aside from that, no.

Contradiction is a bad sign of truth several things which are certain are contradicted several things which are false pass without contradiction. Contradiction is not a sign of falsity nor the want of contradiction a sign of truth

My one ambition was to go to Broadway, and I never gave up on that dream.

Face the giants in your life, slay them, and move on. Do not be daunted by the mistakes and failures in your life.

There are things one must do for oneself.

I really feel there's no limitation on what this band can do in the studio or on the stage. That's an empowering feeling - that we can bring a song to life.

China is important to the world in that they are a force and on the move. Exposing them to figurative art opens up a potential for artistic expression far greater than anyone would ever have dreamed possible until today. It is this very spirit of the struggle and determination to triumph that inspires creative expression.

When I think of any of my successes, I am thankful to God from whom all blessings flow, and to my family and friends who enrich my life.

It's nice to know about something as soon as it happens, and obviously a newspaper can't provide that.
