Should you be worried about over exposure to blue light?

Did you know that the harmful blue light that is emitted from digital screens can cause damage to your eyes, as well as affect your general health and wellbeing? The good news is that Ocushield provides non prescription blue light blocking glasses which can mitigate these harmful effects.

How many hours per day do you spend in front of a digital screen?

Only one or two decades ago, most people would spend far less time in front of their computers, tablets, smartphones or tablets.

However, with the advent of a paperless society and social media platforms, we have naturally been forced to spend at least 8 hours or more each day gazing into the screens of our phones, tablets and computers.

This is, in and of itself, not a huge problem but if you consider that blue light is emitted from each of these devices, you will understand why this has become such a concerning problem.

Aside from dangerous ultraviolet rays, blue light rays have the shortest wavelengths. Scientists now know that the shorter a light ray’s wavelength is, the more harmful it is likely to be.

Recent research has also indicated that children are far more susceptible to blue light than adults. This worrying fact is made worse if we consider that scientists have not had enough time to assess the long-term effects of blue light on children as this has only become a problem in the past decade.  

The effects of blue light should therefore not be underestimated and if you cannot drastically reduce the amount of time you spend in front of digital screens, you should definitely be considering investing in a pair of blue light blocking glasses.

Blue light and your eyes.

The eyes are undoubtedly the organ most affected by blue light. Over time, prolonged exposure to blue light can increase your risk for macular degeneration.

This is understandable when we consider that blue light will penetrate all the way down to the retina. The retina is the back of the eye’s thin and sensitive inner lining.

Too much blue light can damage these light sensitive retinal cells and negatively affect your eyesight.

If you want to avoid eye strain, red or dry eyes and soreness, experts recommend that you either try to spend less time in front of your various screens, or you wear a pair of blue light blocking glasses.

Blue light blocking glasses can be obtained without a prescription, are surprisingly affordable and can really help to protect your eyes.

Can blue light affect my brain?

This is a common question as the brain is arguably one of the most important organs in the body.

When exposed to blue light from digital screens, your brain is tricked into believing that it is still daytime. This is not necessarily a problem during the day when you need to be working, but in the evenings it can prevent your body from producing melatonin.

Melatonin is your body’s way of preparing for a good night’s sleep and, when this is in short supply, it can cause you to have difficulty falling asleep.

Blue light can also affect your sleep and productivity.

Most people are aware that over-exposure to blue light can cause multiple eye conditions, including eye strain, dry eyes, macular degeneration, irritation and more.

However, blue light can have a far greater impact on our health and wellbeing in general.

Many folks enjoy watching television or browsing on their smartphones before going to bed. The blue light emitted from these digital screens can affect our circadian rhythm (which is the body’s natural sleep/wake cycle) and result in poor quality sleep, insomnia and fatigue the next day.

Not being able to sleep properly at night can be a major problem. Apart from being highly frustrating, the knock-on effects are quite serious.

Not getting sufficient sleep naturally results in feeling tired the next day. This can then affect your mood, energy levels and your productivity at work.

If proper steps are not taken to solve the problem of over-exposure to blue light, this can become an ongoing problem.

People who struggle with sleep issues and productivity can take action by investing in good quality blue light blocking glasses and remembering to wear them as much as possible, especially during the evenings.

Avoid exposure now to prevent the harmful effects of blue light!

As mentioned above, the full, long-term effects of blue light have not been studied in great depth as this has only really become an issue in the past decade or so.

That being said, doctors are already noticing patients complaining of multiple issues with their eyes and general health that cannot be explained by anything else other than excessive blue light exposure.

Even if you are not showing signs of the harmful effects of this dangerous type of light form, many experts recommend taking steps now to prevent potential problems in the future.


In a nutshell, most experts believe that people should be more concerned than they currently are about the dangerous effects of blue light.

Conditions caused by blue light have already been extensively studied but the long-term effects are still largely unclear. It therefore makes a lot of sense to try and protect ourselves as much as we can to preserve our health and wellbeing.
