With the pace of digitalisation at its peak, our reliance on digital screens has increased significantly. From waking up with the help of an alarm set on our phones to reading a digital book to soothe us to sleep, digital screens have a profound influence on our lives. What this has resulted in is an increase in screen time, and for most of us it has reached unhealthy levels.
Recently while shopping for prescription glasses online, I came across a category of glasses known as computer glasses, or more popularly as blue light blocking glasses. On reading more about them, I found out that the function of these pairs is to protect our eyes from the harms that an unhealthy screen time might cause.
Why Increase In Screen Time Is A Concern
Most of us have seen our screen time increase, especially after the onset of the pandemic, with things like online classes and work from home becoming an intrinsic part of our lives. Even kids have a high exposure to digital screens these days, and that’s the reason why blue light glasses are being promoted as a great option for kids glasses.
The reason why a high screen time may prove to be unhealthy for our eyes is the fact that digital screens are known to emit blue light. There are strong signs that exposure to blue light can cause harm to our eyes under certain conditions.
Before talking about the harms that blue light might cause, let us understand blue light.
What Is Blue Light?
The visible spectrum of light – the portion visible to the naked eye – has certain components, which are distinguished by their energy levels. Blue light is one of those various components, the part that corresponds to one of the highest energy levels in the visible spectrum. The characteristic of high energy levels is what has made blue light a medical concern.
Among the various sources of blue light, the sun is its largest and the only natural source, whereas things like LED bulbs, fluorescent lamps, and digital screens are its artificial sources.
Blue light emitted from digital screens is a cause for concern because there is more stress on our eyes since digital screens are used in close proximity to our eyes. When it comes to sources such as the sun, the case is not the same as the sun lies far away.
How Blue Light Effects Our Eyes
When our eyes are exposed to blue light under certain conditions, it can be harmful for our eyes, especially when the exposure to it is in excessive amounts, exposure before going to bed, or even under dim light conditions.
The problems associated with blue light in the above-mentioned scenarios include eye strain, dry eyes, headaches, and fatigue. There is also a risk of circadian rhythm – natural wake and sleep cycle – of our body getting misaligned. Prolonged and long-term exposure to blue light emitted from digital screens can also result in complications such as age-related Macular Degeneration.
Do Blue Light Blocking Glasses Help?
The lenses of blue light blocking glasses come loaded with a thin protective coating. It is this coating that makes it possible for blue light glasses to block blue light incident on their surface and prevent it from causing harm to our eyes.
Regardless of the time that you spend on digital screens, it is strongly recommended that you put on a pair of blue light glasses whenever you face a digital screen.
