You might have seen an optical shop promoting its blue light glasses. But why are they so popular? Visio Optical is here to answer a few questions that you might have.
Sitting in front of the screens is now common among people of all age groups. Whether it’s a phone, or a computer, or a tablet, we all spend hours every day in front of these devices. And even more so now, with work-from-home, ZOOM meetings, and all the changes that we have experienced in our routines in the past few months.
Undoubtedly technology has made many things easier. But exposure to screens for long durations can result in harming the eyes. High doses of blue light can cause cellular damage to the retina. Blue light can also impact the sleep-wake cycle.
The best preventive measure to protect your eyes from harmful blue light is to wear a pair of blue light glasses while working with electronic devices. And you can do so, with or without prescription. In fact, even if you don’t need to wear glasses to improve your vision, now you should consider using them to protect the health of your eyes.
What are blue light glasses?
Blue light glasses are glasses with lenses that have special coatings to block or filter out the harmful blue light that comes from digital screens. Blue light glasses or computer glasses help prevent damage to the retina, that prolonged exposure to blue light can cause.
Do blue light glasses work?
Blue light glasses are not the only solution, if you want to protect your eyes from the harmful effects of blue light. Indeed, reducing your screen time is an alternative option to protect your eyes. But what if you can’t reduce your screen time? In the digital world, every individual works on digital screens. We use a phone to accomplish many activities. To work using a phone is very common, and many times it is not really an option.
Therefore, it might not be possible to reduce much our screen time. So, the other option is to wear spectacles with lenses that have blue light filter. People who wear blue glasses while working on digital screens can still be productive, while at the same time getting an effective protection for their eyes. These glasses help to remain fully engaged in the technological world along with preventing the eyes from the damaging effects of blue light.
Should I wear them all the time?
There is no harm in wearing these glasses all day long. However, it is not necessary. In fact, not all blue light is harmful. To be sure, the sun also emits blue light. And a small amount of natural blue light is crucial for good health. It maintains the circadian rhythm, it boosts alertness and memory, it improves cognitive functions and mood.
So, wearing blue light glasses all the time is not required. But, if you work on digital screens for a prolonged duration, you need to consider using them while on screens as blue light from artificial sources has harmful effects.
Do I need them while watching TV?
The most amount of harmful blue light that your eyes receive likely comes from smart phones. That is because we use them for several hours every day. Also, we keep them pretty close to our eyes, and these screens are very bright. But we receive harmful blue light also from computer monitors and television screens, albeit in lower amounts.
So, if you want good protection, the answer is yes. As a matter of fact, televisions are also an artificial source of blue light. So, wearing spectacles with blue light filter can protect your eyes while watching TV.
In conclusion, do not let the blue light harm your eyes. As you protect your skin from the sun, you should also protect your eyes from harmful blue light.
