WHAT IS BLUE LIGHT?

Blue light is a common part of the visible spectrum. In simpler words, it is a component of the light we have all around us. It is in both sunlight and the light emitted by electronic devices, such as computer screens, mobile phones, smart watches, and everything in between.

HOW DOES BLUE LIGHT AFFECT US?

As with any other component of the light spectrum, blue light has its particular purpose. Based on the changing wavelength, blue light rays can range from very dangerous to quite useful (during the day).

Blue light rays with the shortest wavelength have the highest amount of energy and are the most harmful. However, the higher the wavelength the less dangerous the blue light. To be specific, blue light rays with wavelength of 450 nm or shorter are considered very harmful, while those between 470 nm and 500 nm are deemed healthy during the day.

The range of blue light that is healthy for our brain chemistry in daytime helps produce melatonin – a hormone that regulates the body’s sleep-wake cycle. When we take in too much blue light even during daytime often through excessive use of computer or smartphone screens, they hurt our eyes and skin. But in the night time, these harmful effects double up, disturbing the sleep-wake cycle along with more damage to the eyes.

Comment on blue light:

Having learned about the dangers of blue light very early on in 2013 meant, I have been following blue light research closely over the years. The research/knowledge base has increased dramatically compared to what was available in previous years. Now we have epidemiological studies, clinical trials and peer reviewed papers all on how blue light affects our health.

It is now conclusive that blue light emitted from sources such as screens and ambient lighting, can affect three main aspects of our health. Firstly our eyes, by causing eye strain and headaches in the short term but also contributing towards Macular Degeneration in the long-term. Secondly, our sleep by suppressing the hormone melatonin which makes it possible for our bodies to fall asleep. Without the secretion of this hormone, we stay awake essentially. Finally, skin which has come from newer findings. We now know 30 hours of exposure to blue light from smartphone or laptop screens can increase the inflammation level in skin cells by 40%. This means more fine lines and early ageing.

In a digital age, we can’t get away from technology. But, we can be mindful of how we and our families use technology and adjust our environments so our bodies are being protected from overexposure to harmful blue light.

Comment on blue light:

Blue light is a type of visible light with a shorter wavelength, making it emit higher energy. Blue light is not only given off by the sun but also by computer screens, smartphones, flat-screen televisions, and anything that has fluorescent and/or LED backlighting (which includes regular light bulbs btw!).

It is important to understand the effects of blue light because it is not only damaging to the eyes short term, but also long term. Short term blue light effects can make the eyes fatigued and dry. This can contribute to the symptoms of throbbing pain around the eyes - some even suffer from itchy/”burning” eyes. The long term blue light effects can decrease the pigment in the centre part of the vision known as the macula. This can increase the risk of development of macular degeneration - and even blindness.

The sun can actually radiate more blue light than screens. However, with the increasing amount of time in front of/staring directly at screens, we’re starting to see it affect a lot more eyes than the sun. Using blue light filter glasses or screen protectors can help to decrease the amount of blue light that enters the cornea, lens or retina.

Ocushield has a lot to offer for their customers from screen protectors - from electronic devices to blue light blocking glasses. The variety of their products has allowed me to protect many of my own devices to help protect my eyes. This is why I feel so comfortable suggesting these products to my patients. Plus, with their beautiful range - I know they won’t have a hard time finding a product they like, to help protect their eyes!

Comment on blue light:

Sleep has an impact on every single area of our lives, and is the most important behaviour we engage in on a daily basis. Technology usage is another behaviour we take part in on a daily basis, yet it can have deleterious effects upon our sleep. The blue light emitted from electronics tricks our brains into thinking it's daytime. This causes our bodies to decrease the production of melatonin, the sleep hormone, which is the hormone we need to feel sleepy. Ideally, you should turn off all electronics at least one hour before bed, and you should also charge your electronics outside of your bedroom. If you must use electronics before bed for work or school, I always recommend using blue lock blocking products such as those created by Dhruvin Patel of Ocushield. Once you have powered down your electronics, engage in a relaxing bedtime routine in a cool, dark, and quiet bedroom. Having a sleep promoting bedroom environment, a consistent and relaxing sleep routine, and an appropriate and consistent sleep schedule, will keep your circadian rhythm (your sleep/wake cycle) steady, which leads to better sleep. The benefits of healthy sleep are truly endless.

Comment on blue light:

I believe one of the “must have” products of the digital age is a blue light screen protector. Blue light is causing havoc to our sleep cycles, as it suppresses the release of an essential hormone called melatonin. The disturbance of sleep and the lack of quality sleep are not only linked to a host of mental health problems such as heightened anxiety and lower mood - but also decreased levels of motivation, productivity and concentration. As well as poor judgement and problem-solving. To me, it’s a no-brainer. You should add this screen protector to every device in your household, especially as technology becomes more and more interwoven in our lives and the lives of our children. What I really appreciate about the Ocushield blue light screen protector is that it does not change the appearance of my screen at all (unlike my phone’s “Night Mode” or other protectors). I have more energy/focus in my day and my eyes are noticeably less fatigued after hours of sitting in front of my laptop/mobile phone. I highly, highly recommend this product for professionals, parents, and their children.

Comment on blue light:

Now more than ever, sleep is becoming a major factor in our health and wellness. Sleep is not only important to give our body rest but it also gives our brain a chance to flush out toxins that have accumulated throughout the day, which can only be done when we are asleep.

We’ve all heard that phones and screens before bedtime are a big no! But do you know the science behind this? We have a helpful hormone in our body called melatonin, which is secreted in the dark, causing us to become tired and sleepy. In the morning as the sun rises and there is more light, melatonin stops being produced by our body which causes us to wake up! Our laptop or phone screens emit a particular type of light called “blue light”, which stops the production of melatonin. And without melatonin, our sleep quality is greatly compromised!

So how does this affect our body’s overall health? Recent research is showing us that sleep quality also plays a huge role in weight management. Studies are showing us that the less we sleep, the more hunger hormone (ghrelin) is produced and the less satiety hormone (leptin) is secreted. This causes us to eat much more after a night or two of bad sleep. Not only do we overeat because of this imbalance of hormones, but the research is showing we also don’t make the best food choices when our body is in this state! We are more likely to snack and eat energy dense, high carb and saturated fat foods. This can cause weight gain and also long term, can have other implications on our overall health.

Comment on blue light:

Sleep is a crucial aspect of our physical and mental wellbeing. Not getting enough rest has been linked to cardiovascular disease, diabetes, obesity, infection, inflammatory conditions, mood and mental health risks, car accidents, and issues with memory and cognition. Many people have trouble sleeping at night, often thought to be due to insomnia, when in actuality they have a circadian rhythm disorder known as delayed sleep-wake phase disorder, which can be due in large part to the negative impact of blue light.

Blue light, as emitted from our many devices and artificial lights, can be detrimental to our sleep through disruption of our circadian rhythm, or internal clock. Our internal sleep-wake schedule is in large part dictated by the naturally produced hormone melatonin. Our bodies are built so that in the evening when the sun goes down and it gets dark, melatonin is released from our pineal gland, keeping our circadian rhythm in sync and helping us to sleep at night and be awake and alert during the day. Studies have shown that blue light actually suppresses this naturally occurring melatonin release, diminishing one of the major driving forces propelling us to sleep. While in modern society it is hard to completely escape evening blue light, utilisation of blue light filters and low blue light products such as those offered by Ocushield can go a long way to reducing blue light’s deleterious effect on sleep.

Comment on blue light:

One of the biggest advances in human history was the advent of the internet dating back to the 1970s. From there we entered the Information Age, also known as the Computer Age, the Digital Age, or Information Age. Alongside the exponential improvement in technology, the amount of people with personal computers have increased significantly - this rings true in the present time. Outside many factors such as closer working distances, dry work environments, low-blink rates, decreased hydration, poor ergonomics, what we know is that these screens are emitting invisible sources of energy that are being absorbed by our tissues - including our eyes. Though the science is suggestive of certain issues related to eye health, there is still a considerable amount of research that is needed for conclusive evidence. However, time and time again, many of my patients have provided their personal testimonies of how adding blue-light protection to their spectacle glasses or digital screens have helped with eye fatigue, less eye strain, and improved sleep habits. There is definitely something to it - I am a proponent of staying open minded and encouraging my patients to trial blue-light protectors, like Ocushield. As with anything in life, challenges are usually multifactorial, therefore the solutions we seek should also be multifactorial. Considering blue-light protectors is certainly part of the equation that will work complementary to other lifestyle changes.

Comment on blue light:

Blue light can negatively impact sleep by disrupting the body’s natural internal clock - the circadian rhythm. Exposure to blue light at night suppresses the secretion of melatonin, the hormone responsible for inducing sleepiness that can help us fall and stay asleep at night. Blue light is often found in our devices, such as televisions, smartphones, video game consoles, and tablets.

Poor sleep can increase the risk of depression, anxiety, and other mental health concerns. Poor sleep can also increase the risk of metabolic disorders and other chronic medical conditions.

Therefore, limiting blue light exposure close to bedtime is an important aspect of improving sleep at night. This includes dimming lights, minimising exposure to devices emitting blue light at night, utilising night features on smartphones, and using blue-light blocking products.
