Right now, there’s a lot of discussion about blue light and the need for anti-blue light glasses, but
- Do blue light glasses really help, or
- Is this a bunch of marketing hype?
This article will let you know the answers to such questions.
Does Blue Light affect your sleep?
Almost every single day, the first significant thing that you’ll hear about blue light and the need for blue light glasses is that blue light affects our sleep. Blue light has been found in studies to affect retinal cells in the back of the eye, reaching the pineal gland in your brain, which produces melatonin known as the sleeping hormone. The presence of melatonin helps improve your overall nightly sleep, which affects different health aspects. It is found to affect memory, and that’s why people who doesn’t get a good night sleep have increased risk chances for such things.
Most of the blue light you’ll be exposed to is emitted by the Sun and staring at your computer screen or your cell phone for long periods. People who spend a lot of time in front of digital screens are at higher risk of diminishing melatonin production. Blue light glasses are recommended for people who spend a lot of time front of digital screens.
However, overall, it is recommended that people try to reduce screen time. Later in the evenings, try not to use any digital screens in the 2 hours before bedtime. Again, people who spend a lot of time in front of computer screens can consider blue light glasses.
Eye Fatigue Reduction
The second big thing you’ll hear is that blue light glasses helps reduce eye fatigue. It is also known as digital eye strain or computer vision syndrome, which can lead to headaches. There is a lot of disagreement on the scientific validity of these claims. Some studies have found that people benefit from using these blue light protective glasses and yellow filters to reduce eye strain. However, many studies also find no benefit.
What do studies say?
There’s a lot of confusion about blue light and how it could be potentially affecting our vision and lead to different eye diseases such as age-related macular degeneration and potentially vision loss from those diseases. Several studies show that blue light can affect the retina cells in the back of the eye. Other studies also state that our eyes have a lot of protective mechanisms to prevent photochemical damage from this blue light effect.
The Bottom Line
We ultimately know that sitting in front of a screen for long periods of time may result in vision discomfort. There is still a concern because we know that high-energy light can cause damage to the back of the eye, such as in solar retinopathy when somebody stares at the Sun too long, and other high-intensity light beams such as laser pointers also cause damage to the retina. So, in theory, the concern is genuine; however, in scientific studies, the evidence isn’t there right now that blue light causes significant retinal damage.
