Sadly, our modern lifestyles can have a pretty bad effect on our biological sleep cycles. Blue light from smartphones, computers, eReaders and TVs mimics the light from the sun, which enters through our eyes and sends a message to the brain to delay the production of melatonin, the hormone responsible for making us feel sleepy and ready for bed.
While our devices may have evolved, our eyes haven’t quite caught up yet. Blue light registers in the same way as daylight, keeping us alert and awake, and its stimulation interferes with both the quality and amount of sleep we receive – not ideal when we know how incredibly important having a restful night’s sleep is for our health and wellbeing.
Blue light glasses work by filtering out blue light before it reaches your retina, creating a barrier between the screen and your eyes. An anti-blue coating is used to reflect light away and effectively shield users from the disruptive effects of blue light.
Using blue light filtering glasses not only aids with sleep, but can prevent other unwanted effects commonly associated with digital device usage such as eyestrain and headaches.
Not all blue light blocking glasses offer the same range of protection, and some are better suited to certain conditions than others. Our buying guide is here to help you decipher the jargon and the online listings to get the right pair for you!
Glasses with this blockage percentage provide high enough protection from harmful blue light without blocking the vital blue light exposure we require, especially when using electronic devices in places with a lot of natural lighting.
You will want to maximise the amount of healthy blue light you receive during this time to aid in the production of serotonin, the happy hormone, to hopefully keep away the winter blues.
When it gets dark there is less blue light naturally, which is why we tend to fall asleep after sunset and wake up to the sunrise. An absence of blue light at night tells or bodies it’s time to wind down, aiding the regulation of our circadian rhythm.
You should switch to darker lenses at night, around 3 hours before you go to bed. Dark lenses are more efficient at blocking out blue light, which is a good thing when you are preparing to go to sleep.
Wearing dark lenses during the daytime may actually cause sleep disruption rather than prevent it. Not only will light from your screen be blocked, but natural sunlight will be too. This can lead to overproduction of melatonin, causing you to feel sleepy and sluggish during the day when you want to feel alert and awake.
Blue light blocking glasses have traditionally had a reputation of being bulky and unattractive. However, nowadays this is no longer the case and there are now many stylish designs to choose from! But remember to not only think about how they look – try to take into account comfort and fit when making your decision.
Glasses with larger frames may look fashionable, but keep in mind that the bigger the frames, the heavier they will be. Bulky frames also put pressure on the ears and are prone to slipping and sliding on the face, which can be not only painful but very annoying when you're trying to work!
Some glasses have adjustable nose pads which are commonly made from soft, flexible plastic. These are useful for providing grip and can be moulded to fit the individual’s face.
Other styles of frames have an inbuilt nose bridge which may be preferable to those who would rather have the weight of the glasses evenly distributed across the nose, rather than focused at two points.
When glasses lenses are too big or too small our eyes have to work harder to focus, leading to eye strain and headaches. Furthermore, lenses which do not adequately cover the eyes will do a poor job at shielding from blue light.
For the most comfortable fit, when looking forward, your pupil should be on the horizontal centre in the top third of the lens. Once you know the size of your preferred lenses, you can use a ruler or tape measure to check whether they will be suitable for your eyes.
