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.

Thus, the Archivist must display at all times scrupulous independence and a devotion to the laws and principles which govern the responsibilities of the office.

They said if I could deal with the pain, I should play. So, I did, and for some reason, I started hitting. It was a weird thing. I don't know if it was because I couldn't do too much, and I was just trying to stay up through the middle and not hurt myself.

My first experience with gymnastics was when I was in daycare. We took a field trip to a gym, and I was hooked.

Obamacare is not about improved health care or cheaper insurance or better treatment or insuring the uninsured, and it never has been about that. It's about statism. It's about expanding the government. It's about control over the population. It is about everything but health care.

And unless you have that sense of being creative, people think you're just working all the time.

The Welsh people have a talent for acting that one does not find in the English. The English lack heart.

Stay out of the loop, the club, the inner circle.

Say a piece of pottery is broken, and it's fixed, and they use gold in the adhesive and in the sealant. It becomes more precious than it was before it was broken in the first place.

The problem is, when you come back in you're sweating, so I wait until the very last minute before putting on my shirt so that it's not covered in sweat.

Fasting is a constant means of renewing yourself spiritually.

I would love to be in musical theater and be on Broadway. If someone were to offer me a position to do something like that, I wouldnt pass it down. Im a huge fan of musicals and I really want to do that.

I've never been able to sky-dive, and I've always wanted to. I've probably done everything else, but for some reason the insurance company won't let me do it.

You come to Washington, there's a rail bill, there's a highway bill, there's a aviation bill. But when you go home, there's an airport, there's a highway, there's a rail, there's transit. It all has to work together.

People who care about animals tend to care about people. They don't care about animals to the exclusion of people. Caring is not a finite resource and, even more than that, it's like a muscle: the more you exercise it, the stronger it gets.

As soon as you find the key to success, somebody always changes the lock.

I am a bit prudish, I think. It's hard for me to write about sex, and I don't really care to read about it, either.

Who wants to be normal when you can be unique

I really like action-dramas like 'The Professional' or 'La Femme Nikita.' I'd really like to be in a movie like that.

It's changing a bit, but the thing in LA is everyone is either in the industry, or knows someone who is in the industry. So, they don't let on that they recognize you, that's what I've found out.

My distinguishing feature is the gap between my teeth. I had to wear a brace because my teeth used to stick out like guns from a fortress.

NASA's been one of the most successful public investments in motivating students to do well and achieve all they can achieve, and it's sad that we are turning the program in a direction where it will reduce the amount of motivation it provides to young people.

Don't get me wrong - what we do is important. But it is infinitely less important than what Jesus has done for us.

Unfortunately for the 'Tomorrow' series, I feel that for the actors that were in the first film, maybe our commitment to it is done.

Museums are wormholes to other worlds. They are ecstasy machines. Follow your eyes to wherever they lead you…and the world should begin to change for you.
