The good and bad of Blue –All you need to know about Blue Light Protection
What on earth is Blue Light?
Blue Light, a natural part of visible light, is everywhere. Wherever you look, there are blue light emissions. Take the sun for example; it’s the largest source of blue light and being outdoors during the day is where we’re most exposed to it. But blue light can also be emitted artificially, through the daily use of digital devices like your smartphone, tablet and laptop.
Our modern lives revolve around our screens. We wake in the morning and check our phones, we work all day on our laptops and come home and spend hours scrolling through Instagram. The last thing we do before we sleep is check our phones just one last time. The exposure to blue light from digital devices is small in comparison to that of the sun, but the amount of time spent on our screens and our close proximity to this artificial blue light is a rising concern for eye care professionals.
And like most things in life, blue light comes in two forms; good and bad.
What is "good" blue light?
Good blue light boosts alertness, helps memory and cognitive performance and elevates our moods. Those happy vibes you feel on a warm sunny day are partly thanks to the “good” blue light that you’re basking in. In fact, in some climates where sunlight is scarce during winter, people have less blue light exposure and may develop seasonal affective disorder (SAD) in which they feel tired and depressed. Therapy lights that emit long blue light wavelengths are a common treatment for SAD.
Exposure to blue light during daytime hours also helps to regulate our sleep/wake cycle and is essential for a restful night's sleep.
When does the “good” become “bad”?
Harmful blue-violet light has been identified as the most dangerous. Over time, exposure to harmful blue light could cause serious long-term damage to your retina and potentially increases the risk of eye diseases such as age-related macular degeneration (AMD), cataracts and photokeratitis (sunburned cornea), which can lead to temporary blindness.
Too much exposure to blue light late at night through digital devices can disturb our sleep/wake cycle, leading to problems sleeping and daytime tiredness. This also leads to digital eye strain which causes headaches, dry and tired eyes, blurry vision, eye irritation, poor sleep and an inability to focus. The importance of protecting our eyes from the harmful rays of blue light cannot be overlooked, especially in an age where digital devices are a way of life for most of us.
How do we protect ourselves against the”bad” blue light rays?
