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.

so pretty, and they work wonders. Being a school student I have spent hours looking at my computer screen, and I haven’t had sore eyes or a headache since getting them!

Fast delivery

Excellent product

Who knew?

As someone with full vision and working with screens all day, I have had prescription reading glasses before for visual enhancement and they’ve always resulted in sore eyes and tiredness. Wearing Widok I was amazed at how the blue light difference served as both the sharpness and colour rendering I needed. This is the way of the future.
