The High Energy Visible (HEV) blue-light emitted by all digital screens can trick our brains into thinking it’s the middle of the day. That is because HEV light is the same type of light that is emitted by the midday sun.

Millions of years of evolution have trained our brains to be most active and alert in the middle of the day. In the modern age, when we are staring at HEV light before bed-time, our brains are tricked into becoming more alert, which prevents from falling asleep easily and naturally and not getting a good nights’ rest.

Blue-light blocking computer screen glasses block specific frequencies of HEV blue-light, so that we can now use our screens safely before bed time, and still get a good night sleep.

All digital screens emit a High Energy Visible Light (HEV), which we see as blue-light. This includes modern TV’s, laptops, tablets and mobile phones. Too much exposure to HEV light can strain your eyes causing Digital Eye Strain, and also mess with your circadian rhythms (see the section below).

Blue-light blocking glasses prevent blue-light at specific frequencies from hitting your eyes, allowing you to use your screens without getting the many symptoms of Digital Eye Strain, which can include;

• – Sore, tired, burning or itching eyes.
• – Watery or dry eyes, blurred or double vision.
• – Headache.
• – Sore neck, shoulders or back.
• – Increased sensitivity to light.
• – Difficulty concentrating.
• – Trouble keeping your eyes open.
