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.

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.

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.

I guess that in this process of trying to incorporate or to be faithful to the films I admire so much, that's how I start to find my own voice. The admiration I have for filmmakers, this gratitude, perhaps that's my only way to become specific.

It is not hard to obey when we love the one whom we obey.

I'm a conduit for telling people's stories. It's a privilege.

Include me out.

I do believe in love; it's wonderful - especially love third time around, it's even more precious; it's kind of amazing.

No worthy enterprise can be done by us without continual plodding and wearisomeness to our faint and sensitive abilities.

I myself, as well as Toyota, am not perfect. I, more than anyone, wish for our customers' cars to be safe.

'Syndicate' is technically the first game I worked on.

Once you've been around this business long enough, anything is a possibility. It's a business first and foremost. Guys play it because they love it, but it is a business, and if you don't understand that it's a business, you're lying to yourself.

They cannot see that we must lay one brick at a time take one step at a time.

No great achiever - even those who made it seem easy - ever succeeded without hard work.

I sustain myself with the love of family.

The spirit of liberalism is to create free men; it is not the regimentation of men.

Beyond 2050 the world population may start to decrease if women across the world will have, on average, less than 2 children. But that decrease will be slow.

An Apostle is a missionary, bearing testimony of the reality and divinity of Jesus Christ in all the world.

I don't care how I got here. In the books, when you look at it 10 or 20 years from now, it's not going say how he got here, it's going to say he's here and he represented the team.

If you double the number of experiments you do per year youre going to double your inventiveness.

I believe the Bible is the word of God from cover to cover.

I know one day I'll be considered too old.

We tend to idealize tolerance, then wonder why we find ourselves infested with losers and nut cases.

It's very rare that a song falls from your mind complete.

I don't think I can play Mr. Bachchan.

Elvis Presley, The Everly Brothers, and a lot of American artists were my greatest influences.

Every person is so different and I don't think there is an exact match for every person. If you meet someone and they have 20 of the 25 things you want in a person, then you're pretty lucky.
