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.

A lot of people assume that once you're working in Hollywood you become some sort of glamour-diva, which could not be further from the truth about me.

As a kid I would be put to bed when my parents had guests and because I was such a show-off I would go to my mum's room, put on her nightdress and Jackie Onassis shawl, run downstairs, go outside, ring the doorbell and pretend to be one of the guests. I'd say, 'Hello, I'm Mrs. So-and-So.'

I think that writers of literary fiction would do well to read more books for children.

My imagination is my polestar; I steer by that.

I always managed to get in trouble, like every kid. But I had to learn a lot of hard lessons on my own, without parents who would nurture me and guard me through that part of life, at a very young age.

When I was young, I was rather attractive, and I thought that I would be a leading lady. I always thought of myself as a dramatic actress, but of course the opportunities for blacks weren't there at the time.

In the end there doesnt have to be anyone who understands you. There just has to be someone who wants to.

Since Sunrun introduced solar as a service in 2007, it has become the preferred way for consumers to go solar in the nation's top solar markets. Sunrun has deployed more than $2 billion in solar systems and has raised more than $300 million in equity capital.

Instead of looking for love, let it happen by being the best you that you can be.

This idea that you can watch a show like 'True Detective,' and it was awesome, but is it really ruined for you if the finale is not your favorite episode of it? It's just odd to me.

I want to produce the best popular music I can.

No, I'm a theatrical, live performer or a movie performer.

The athlete of today is not an athlete alone. He's the center of a team - doctors, scientists, coaches, agents and so on.

Every patient tends to bury the most important story inside some other story, just the way new writers often 'bury the lede.' 'Burying the lede' is an old journalism term for when you only find out the real point about halfway into the article, but it also applies to therapy.

Those who can win a war well can rarely make a good peace and those who could make a good peace would never have won the war.

My fiction-writing DNA shows in how I think about prose, how I think about the page, how I think nonfiction stories should work. And every piece of nonfiction I write, I want it to have fictional texture.

Pride slays thanksgiving, but a humble mind is the soil out of which thanks naturally grow. A proud man is seldom a grateful man, for he never thinks he gets as much as he deserves.

When you're an experienced celeb - which I am - you sometimes just need a bit of space, when you're not 'on'. I'm always on!

Write to be understood speak to be heard read to grow

I love being creative in all forms.

There are gender health differences and we need to know what they are.

Being one step ahead of a fashion trend is not so important to me. What matters is to always forge ahead.

Even now, my husband Jerry, our son Matthew and I live only five minutes away from my parents home, and my brothers live about ten minutes away. It's been great having such a supportive family.

I feel cheesy when I see 'Silver Spoons.' Some of it was funny, but some of it was just cheese! My kids love it, but I look at it and cringe.
