Difficulty focusing after using a computer for long periods of time is another symptom of digital eyestrain. What is digital eyestrain? well it is a combination of the symptoms described above brought about through excessive exposure to blue light and flicker from digital devices and office and home lighting.

How to treat digital eyestrain

Always seek advice from your doctor and discus symptoms of digital eyestrain.

Blue light Glasses AKA Computer Glasses  

Reducing the amount of blue light that reaches your eyes is the first step. By wearing a pair of blue light glasses, often called computer glasses you can reduce blue light during the day time. Be careful though as most companies will only focus on violet light which does not impact digital eyestrain, its blue light you need to filter.

Not all computer glasses will actually filter the blue light as they claim Fortunately there is some that are backed by science and are by far the best computer glasses as they target the whole blue spectrum and filter it down. Remember you do not want to completely block blue light during the day as this will disrupt you natural biological rhythm, instead focus on filtering blue light down to help prevent digital eyestrain.

Blue Light Glasses AKA Blue Light Blocking Glasses

Light is made up of particles that travel in waves which emit energy. These particles range in length and strength for example the shorter the wavelength the higher the energy, and the longer the wavelength the lower the energy. Wavelengths of light are measured in nanometres (nm) and each wavelength range is a different colour.

Blue light is found both naturally and artificially. When you go outside blue light is emitted from the sun. Blue light from the sun is essential in regulating your sleep and wake cycles and your body clock. Blue light has also been shown to improve alertness, reaction times and create a sense of wellness. Blue light from the sun is essential. Blue light from the sun is also accompanied by all the other colours from the light spectrum, making it a balanced and healthy light source. In winter months when the sun does not come out we can suffer from Seasonal Affective Disorder (S.A.D) which lowers mood and heightens feelings of depression and anxiety.

Blue light is also found artificially from electronic devices which include your smart phone and computer screens, as well as from light bulbs.

The Dark Side Of Blue Light

We know that the shorter the wavelength of light the higher the amount of energy it contains. Blue light found at the very beginning of the visible light spectrum meaning it contains intense amounts of energy. Blue light ranges from 400-495nm. The light found in digital devices and light bulbs contains far more blue compared to other colours in the spectrum meaning our eyes are receiving too much unbalanced blue light. This blue light penetrates the eye and over the course of a day will cause digital eyestrain. Digital eyestrain is characterised by dry itchy eyes, headaches and fatigue. Digital eyestrain can also progress into macular degeneration over time. In winter, the sun does not come out as much as the summer months which leads us to use more artificial light sources. This contributes to S.A.D by keeping our cortisol levels (stress hormone) chronically high as excessive blue light raises your stress hormones. Coupled with lack of sunlight this can lead to stress, anxiety and depression.

A Case of the Blues . . .  and Greens

Our body clocks and sleep wake cycles are entrained by blue and green light. In the morning when we see blue light from the sun it tells our brain that its day time and to make us feel alert and awake. When the sun sets and it becomes dark the removal of blue and green light tells our brain its night-time. This sends a signal to the brain to secrete melatonin (sleep hormone) which then makes us feel sleepy and eventually sends us to sleep. 

Green light that disrupts our sleep is found between 500-550nm and is just as influential at disrupting our sleep as blue light. In modern society, after dark, we now switch on our cell phones, watch TV or turn on our house lights which all contain blue light. This blue light sends a message to the brain telling us its day time, so we do not need to relax or feel sleepy. Exposure to blue and green light from digital devices, TVs and light bulbs after dark is disrupting our sleep. Harvard University has shown that exposure to blue and green light after dark disrupts our sleep and increases our risk of type-2 diabetes, depression, heart disease, anxiety and cancer.

Beating the Blues

To effectively combat the negative effects of artificial blue light during the day its essential to wear blue light filtering computer glasses. These glasses filter out harmful blue light from digital devices allowing you to beat digital eyestrain. To beat S.A.D along with depression and anxiety it is paramount to wear mood booster glasses that contain a light-yellow lens. This helps reduce the stress causing wavelengths of blue light whilst brightening up your view on the world. In order to get the best night’s sleep, it’s a must to block blue and green light after dark with red lens blueblocker glasses. This way melatonin can be produced effectively and diseases such as cancer, diabetes, heart disease and depression can be avoided.
