Consider choosing an Intraocular lens (IOL) that protects eyes from blue light. This will replace a cloudy lens during cataract surgery.

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.

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.

For the last thirty years in my career I never know what I'm doing next.

These are times of unprecedented challenge and change in the airline industry, and the appointments we are announcing today will put American in an even stronger position to continue the substantial progress that has already been made under the tenets of our Turnaround Plan.

This Administration has led us into an area without vision. Bush has no clear understanding of what is being asked of the citizens, and the military is under his direction.

If liberty and equality as is thought by some are chiefly to be found in democracy they will be best attained when all persons alike share in the government to the utmost.

I'm still really fascinated with characters and people and telling their stories.

I will be a president in a skirt, but I will wear the pants.

Easy, simple and great laws, which await nothing but a sign from the lawgiver to spread prosperity and vigour throughout the nation, laws which would earn him immortal hymns of gratitude down the generations, are those which are least considered or least wanted.

We should seek the greatest value of our action.

I think every movie changes me and is life changing, especially movies you direct.

My coach and I will have these arguments where I am in pain or something is wrong, and I won't tell him because I feel like I need to train. We have a blow-up of arguments, and he says, 'Shelly, you need to tell me when these things are happening.'

I'm not a machine. I get really motivated, then I fall off the wagon and want to eat Chinese food and sit on my couch and gain five or 10 pounds!

There's something about being rejected - when I go out without my friends, I'm reminded of how I'm actually quite antisocial. I don't look like a guy who feels like that, but it's very hard for me to start up a conversation. At a party, I'm lost.

The woman who can't influence her husband to vote the way she wants ought to be ashamed of herself.

The American people are smart. They've gotten sick of the predictable hyperpartisan talking points and canned anger.

Always go with your passions. Never ask yourself if it's realistic or not.

I'm an entertainer, period. But I'd probably have to say my passion is in singing. I'm willing to go broke singing.

I don't want to make any judgments, and I don't want to preach, but I'm hoping that marriage can work: that when people do fall in love, when people do find their soul mate, everyone sticks to it. It has the potential to be a very powerful thing, marriage.

In life, if you don't know the truth, then you can't be free, because then you'll believe that the lies are the truth. But once we realize that when we read the Word of God, and you know the truth of who you are, then I'm not a man without arms and legs. I am a child of God.

For young people, it doesn't matter so much, but when you're older, less is definitely more - too much make-up can give you the 'eccentric Aunt Sally' look!

By providing memorable social media customer service, companies not only create deeper connections with consumers, but they glean valuable insights on how to improve their products or services.

If I get blocked, it is generally because I don't know enough about some aspect of the story or the characters. The answer for this is generally more research, or making more background notes, so the place and person can be more fully realized inside my own mind.

I am aware of the sufferings of women in India, which is also the suffering of women in many, many countries on our planet. My heart is filled with empathy and love for them.

Grandma cheated whenever she could. She cheated because it was a much more scientific and surer way of winning than trusting to luck.

Smells are surer than sounds and sights to make the heartstrings crack.
