Computer Glasses and the War Against Screens and Blue Light

Many believe that computer glasses are silly and are just an added, unnecessary expense. Despite spending hours in front of computer and phone screens, they forgo getting these glasses for this reason. However, many studies have emerged showing the ill effects that computer screens – or gadget screens, in general – have on our health. One way to combat these ill effects? Glasses made specifically for computer or gadget use.’

Why Are Computer Glasses Necessary?

Since the dawn of the computer, people have been spending more and more time in front of screens. Being in front of a screen is practically a norm – it’s part of our everyday lives. In January 2019, Forbes released an article that revealed how much time Americans spend in front of screens and the data they reported is quite concerning.

Apparently, the average American spends as much as 12 hours in front of screens while at home. This does not include the time they spend in front of screens at work or while at school. It seems that TV, computers, phones, and other gadgets have taken over our lives!

Although such extremes would call for a complete lifestyle change to detox ourselves from a life of screens, not everyone has this luxury. For the most part, screens are unavoidable. People need to use them at home, at work, at school, and for everyday communication. So, since they can’t be avoided, computer glasses were created to be used in conjunction with these screens, instead.


Why Protective Computer Glasses?

People aren’t just concerned about how overexposure to screens make us zombies. It’s what these screens emit that is most concerning: blue light. Protective glasses are able to limit – if not totally eliminate – one’s exposure to blue light.

Blue light is part of the dangerous, visible light spectrum. Basically, visible white light is red, orange, yellow, green, blue, indigo, and violet light (yes, like a rainbow!) combined. Compared to the other lights, blue lights have the highest energy and the shortest wavelengths. When light looks white, it could mean that it has a large blue component.

Digital screens are designed to emit bright, white light, consequently emitting large amounts of blue light as well.

Blue light isn’t necessarily bad, though. It’s proven to boost alertness in people. It can aid in memory and elevate one’s mood as well. Exposure to blue light during daytime hours can help maintain a healthy circadian rhythm.

But as with everything else in life, too much blue light can cause problems to one’s health.



How Blue Light Negatively Affects the Human Body

Blue light can negatively affect our eyes. Hours upon hours of staring at a screen can leave one with strained, tired eyes. Blue light can reach all the way to the eye’s retina and overexposure can damage light-sensitive cells in that area.

Aside from that, overexposure to blue light can wreck one’s circadian rhythm especially when exposed late at night. Because it boosts alertness in people, it can disrupt our natural sleep-wake pattern and cause sleeping problems and insomnia.

Sleeping problems open up people to a plethora of different health issues including diabetes, cardiovascular problems, and depression.

How Protective Computer Glasses Protect Us from Blue Light

Computer glasses are considered a type of specialty glasses much like reading glasses. Reading glasses were made to magnify print so we don’t overwork our eyes to try to read them. The former allows us to deal with blue light and the glare of computer or gadget screens.

Unlike reading glasses, however, their lenses have a special coating or filters that either block or absorb blue light so they don’t reach your eyes. So, if you’re staring at a screen, especially during nighttime hours, you’re not as exposed to blue light as you would be without them.

This doesn’t mean that they should only be worn at night, though. Some blue-light-blocking glasses also have additional features that help reduce eye-strain and retina damage caused by computer glare. In fact, most glasses are actually meant to be worn during the day when you’re working in front of a computer – just more so at night so as to not disrupt your sleep-wake cycle.

Choosing the Right Pair of Computer Glasses

Not all protective glasses are created equally. When choosing the right pair for you, you’d have to think about your priorities and your reason for buying one in the first place.

Some glasses focus more on filtering out blue light and they do so by increasing the yellow or red tint of their lenses. Glasses like these are more suitable for those who are exposed to screens at night. Depending on the tint strength, they filter out blue light so as to not suppress your body’s melatonin levels. This means that with these glasses, even if you check your phone or use your computer late at night, your sleeping pattern won’t be negatively affected – you’d ideally still be able to get a good night’s sleep once you decide to go to bed.

Other glasses prioritize aesthetic. This may sound shallow but it just wouldn’t be a good look when your boss sees you using literal rose-tinted glasses at work. Yellow and red tints just aren’t for everyone, too. Some people find tints distracting and some just like seeing colors as they are. So, these glasses are made to filter at least 50% of blue tight without giving its user a yellow or red tint.

Then, there are glasses that function as all-purpose ones. You may use them to block out blue light from screens, eliminate glare, and even block out UV light – further protecting your eyes from strain. Glasses like these are for people who just can’t be bothered switching out specialized glasses for different purposes.

Whatever pair you choose, for whatever purpose, getting computer glasses to protect you from all the health problems blue light can bring is simply just a good idea. After all, prevention is better than cure in this war against screens and blue light!
