Blue light filtering

Blue light has a very short wavelength, and thus produces a greater amount of energy. Sources of blue light include the sun, digital screens and devices such as TVs, computers, laptops, smartphones, tablets, fluorescent and LED lighting.

A headache is a common symptom that is caused by too much stress on the eyes. People who are already light sensitive can trigger migraines from blue light exposure.


Because your eyes are working hard to cope with blue light, they begin to experience eyestrain. Over extended periods of blue light exposure can cause long-term vision issues such as cataracts, or age-related macular degeneration.

Trouble Sleeping

A common habit before going to sleep is checking emails or catching up on social media. However, at night, blue light disrupts our circadian rhythm, the natural release of melatonin. The blue light tricks our brain into thinking it's day-time, thus causing trouble falling asleep.

Blurry Vision

Long periods of focused work at a computer screen can cause eye fatigue. Give your eyes a break after 20 minutes, because our eye's natural filters are not designed to block out blue light.
