What is ‘blue light’?

 

Natural and artificial light is made up of various wavelengths of different colours. Blue light is part of the light spectrum, vibrating within the 380 to 500 nanometre range. It has the shortest wavelength and the highest energy. Overall, about a third of all visible light is considered high energy, or "blue," light

 

Is blue light damaging to the eye?

 

In large amounts, high energy light from the sun such as blue light, can increase your risk of eye disease. This has started to raise concerns about whether blue light from digital screens is harmful to the health of our eyes.

Digital eyestrain, is believed to affect about 50% of computer users. Digital eyestrain an cause symptoms such as dry eyes and blurred vision.

Almost all blue light passes straight through to the back of your retinas and studies have show that blue light could be linked to causing damage to them, however, the amount of damage depends on the wavelength of the light and how long you are exposed to it. It has been found that filters which cut out up to 94% of blue light can help to decrease the damage to your eyes.

 

Is blue light an increasing threat? 

 

Over the years, the use of LED and fluorescent lighting has significantly increased, this comes from using devices such as tablets, smartphones and computers. These have higher levels of blue light than things such as traditional light bulbs. However, they give off less blue light than natural daylight. Despite these devices being within international safety limits, research has suggested that increased exposure to blue light can cause eye strain and fatigue and may also cause sleep dysfunction.

 

Are there health benefits of blue light glasses?

 

While blue light blocking glasses are effective at reducing the amount of blue light that enters your eyes, there is no research to suggest that this improves or protects the overall health of your eyes. Therefore, there is no scientifically proven benefit of wearing blue light blocking glasses for your eye health.

 

What about blue light filters on spectacle lenses?

 

Blue light filters may help to reduce eye fatigue, enhance sleep, and preserve eye function. However, due to there not being significant scientific evidence, there are no guaranteed benefits. Although, people with issues that could be related to blue light, may request blue light lenses to see if they help.
