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 with modelling and acting these days, the lines are blurred. Everyone can do all sorts of things, so why do just one?

The Internet is amazing.

I've always had tremendous support from my parents. I think there's a myth that gay people have lousy relationships with their parents.

Sometimes it's not how GOOD you are, but how BAD you want it.

Continuous present is all we have, and stream of consciousness - which in a novel is arguably just as artificial as the stilted dialogue that you get in most conventional novels. They're all stratagems to try to get closer to the texture of lived life.

The role of Rimbaud is one of the most important roles to play for a young actor.

Good leaders need a positive agenda not just an agenda of dealing with crisis.

Being very famous is not the fun it sounds. It merely means you're being chased by a lot of people and you lose your privacy.

Social media is great, I guess, but it feels like technology is the sapper of innocence.

The Oscar is very beautiful, utterly mesmeric, but I don't feel any more important because I have won one. It doesn't mean I'm any better than anyone.

As a five-year-old kid, I used to sit in front of the TV - I never missed 'Dukes of Hazzard,' not once. It was me and my dad's show.

It is only partly true that religion does more harm than good in society. The community makes God into the image it wants, vengeful, or milky sweet, or scrupulously just, and so on.

Bureaucracies are inherently antidemocratic. Bureaucrats derive their power from their position in the structure, not from their relations with the people they are supposed to serve. The people are not masters of the bureaucracy, but its clients.

I think it's important that you know every detail when you open a store, that you pay attention to everything.

I will not be as those who spend the day in complaining of headache and the night in drinking the wine that gives it.

Solemnity in politicians is not only tiresome but may even mask those twin sins - self-righteousness and intolerance - for the opinions of others. If I couldn't laugh, I couldn't live, especially in politics.
