Disturbed Sleep
Long and excessive exposure to devices that produce artificial blue light in the evening and nighttime disrupts our natural sleep-wake cycle by tricking the brain into not producing melatonin before bed which can lead to sleepless nights and tired days.
Digital Eyestrain
We are exposing ourselves to blue light for longer periods of time and at a close distance. This can cause eye strain because blue light penetrates all the way to the retina and can be the source of blurry, tired and damaged eyes.
Headaches
A headache is a common symptom that is caused from too much stress on the eyes. People who already suffer from sensitive light can trigger frequent headaches and migraines from exposure to blue light.
