Digital Eye Strain
With technology now a significant part of our everyday lives, Digital Eye Strain is a fast-growing problem that affects many people.
As technology has become an integral part of our everyday lives it is hard not to rely on our devices whether it be for work, staying connected to family or friends or online entertainment platforms.
Digital Eye Strain (DES), also known as Computer Vision Syndrome (CVS), is an ever growing problem for people today. Side effects include blurred vision, headaches, fatigue and dry eyes. Digital Eye Strain occurs when we spend prolonged periods of time looking at screens, causing our eyes to feel strained and fatigued.

Blue Light
Blue light is type of light that is emitted from the sun and is vital to keeping our body clock in sync with day and night time (known as your circadian rhythm). Blue light is used by nature to trigger our bodies to become alert and wake up.
However, blue light is also emitted by technological devices such as phones and laptops. When screens are used for prolonged periods, and especially in the evenings, the unnatural blue light exposure can cause side effects such as sleep disruption and fatigue. This is why many find it difficult to sleep at night if they have been using technology, as the blue light is disrupting the body clock.

Prevention
Blue light glasses and blue light lens coatings are a great way to filter out the blue light from all of our devices, resulting in less strain on the eyes - and you'll feel more energised after a day on your screen too!
Blue light glasses don't have to be prescription. They are just plain lenses, with no prescription, but with the blue light filter incorporated for protection. Available both online and in-store for all ages, we have a variety of blue light screen glasses from the funky brand French eyewear brand IZIPIZI.
IZIPIZI has a range of glasses in all different colours and sizes, with a lightweight rubber feel. The IZIPIZI screen range filters 40% of the blue light, ensuring maximum protection of your eyes, so you can use your screens knowing your eyes are being looked after!

ZEISS Duravision Blue Protect
ZEISS Duravision Blue Protect is a lens coating that is able to be put on all prescription glasses to ensure that your eyes are protected from blue light when using screens.
At OCULA, we recommend ZEISS Duravision to those who use screens regularly to prevent Digital Eye Strain and provide comfort when using technology.

I don't have symptoms of digital eye strain, should I still wear blue light glasses?
