Blue light glasses have gained popularity over recent years due to the increasing usage of digital devices. Both adults and children spend more hours a day looking at monitors and smartphones. This article explains what blue light glasses are and the ways in which they are beneficial.
What are blue light glasses?
Blue light blocking glasses have been specially designed with lenses to filter out and block the unwanted hight-energy visible (HEV) blue light given off from digital screens. Wearing blue light glasses can help reduce the effects of exposure to blue light.
Rays on the blue end of the light spectrum are high energy and have the shortest wavelengths. Therefore, the light gets scattered into other directions causing haze and blur on screens, making it difficult to focus. This can lead to digital eye strain and fatigue.
Do blue light glasses really work?
Whilst blue light glasses block blue rays, other precautions can be taken to further prevent eye issues caused by digital screens.
Many eye problems caused by digital screens fall under a condition which we refer to as Computer Vision Syndrome. They result from constantly shifting your focus while looking at the screen and are also caused by the glare and contrast.
The Vision Council, a body representing the optical industry, recommends using blue light glasses to reduce eye strain. However, in addition to wearing blue light glasses, you should take on board the following tips in order to further prevent eye strain and irritation:
Practice the 20-20-20 rule – this rule states that you should take a break of at least 20 secs, every 20 mins and look at least 20 feet into the distance
Keep your eyes lubricated throughout the day with eye drops
Sit an arm’s length from your screen to prevent eye strain
You can also lower the screen so that your eyes are not so widely open. This will prevent dry eye as when looking down, your eyes are slightly hooded which protects the tear film from evaporating
Blink regularly – this will help replenish your eye’s own tears and prevent dry eye
Adjust the settings on your monitor – the brightness of your screen should match the brightness of your surroundings and the text size and contrast should be easy to read. You can also adjust the colour temperature on your monitor to reduce blue light
Adjust the room lighting – using proper lighting around your computer and make sure there is no shadowy areas or glare from lamps
If you’re a contact lenses wearer, you may experience worsened symptoms of irritation and dryness. It’s Important to try and give your eyes a break by wearing glasses from time to time. You can also consider silicone hydrogel contact lenses as they allow more oxygen to reach the eye compared to standard hydrogel lenses.
Do blue light glasses help with eye strain?
Yes, blue light glasses help minimise the digital eye strain put on by looking at screens all day.
Blue light reduces our production of melatonin (sleep hormone) which help us sleep at night. Inevitably, this causes us to stay awake longer at night and excessively stare at our screens. This will not only disrupt our sleep cycle but also lead to eye strain. For this reason, you will find blue light lenses help with both sleep and digital eye strain.

You might need blue light filter glasses if you are overly exposed to digital blue light. The primary source of blue light is emitted from the sun and by artificial sources such as digital screens and modern lighting. It’s the blue light from digital devices that can impact our eyes. So, if you spend a lot of time in front of your phone, tablet or computer screen, blue light glasses might be the answer to reduce eye strain and optimise your visual comfort.
