What is Blue Light? 

Blue light (HEV) sits in the middle of the ‘light spectrum’, between visible light and ultraviolet light (UV). Sunlight is our main source of natural blue light, which is why we associate blue light consumption with daylight. Man-made sources of blue light include computers, phone, TVs and tablets, which emit significant amounts of blue light in close proximity to our eyes.

*Fun fact – HEV (blue light) rays are what make the sky look blue!

How Does it Affect Me?

With the increase in the use of technology and the proximity of our screens to our eyes, this blue light can have an affect on our overall eye health. Eye strain and headaches are among the most common side affects of harmful blue light consumption, as well as restlessness and trouble sleeping due to the association of blue light with daylight, often tricking the mind into thinking it’s time to get moving.

Great product

This protects my eyes and is great for the amount of screen time I do (over 8 hours sometimes per day).

Instant relief and super comfortable

I never buy glasses without trying them on. I was given the website by someone I met who had purchased some and found they stopped her headaches. I could feel the relief on my eyes in just half an hour of wearing them. And they are very light and comfortable. The service was quick and efficient. Nice to buy out of Australia too.

OMG 🤩 They work!

I was sceptical about these but they looked so good and They Work! I never realised how much blue light the computer screen/laptop gives off and these really did remove that. It made the screens so much easier to look at while I’m working. Great product - they fit perfectly and everyone who has zoomed with me loves the look. So happy 😁
