While we all love to spend time on our smartphone and computer, not many of us give a thought to what it does to our eye health.
We are not saying that you abandon your digital devices. We know it is just not possible. Some of us have online classes to attend and some of us have work to do. But this does not mean that you cannot do anything about it.
If you are aware of the possible risks and use blue light glasses when looking at digital screens, you are treating your eyes well. In case you don’t know why your eyes need protection from digital devices, this blog is all you need.
We will tell you why you should never look at digital screens with bare eyes and how wearing glasses can actually give protection against the potential damage.
What is blue light?
Your digital screens are really helpful, but they can also harm your eyes. Blue light is a harmful artificial light that comes out from digital devices and impairs your vision. It hampers the macular(the part of the retina that supports central vision) health of your eyes leaving you with poor eyesight.
We often feel headache, dry eyes and blurry vision after we have been exposed to our digital screen for too long. Blue light is the reason why we feel this way. Not only this, long-term exposure to blue light can cause severe damage to our retina triggering eye problems such as age-related macular degeneration and computer eye syndrome.
If you have a vision problem and your optician has prescribed you to wear varifocal glasses, make sure you have them on when you are working on your device. However, if your vision is normal, don’t be careless and wear good-quality blue light glasses when using digital media.
How do blue screen glasses work?
The digital screens give out blue light containing electromagnetic radiation in a wide range of frequencies. Blue light blocking glasses (or computer glasses) filter out this damaging light while also protecting your eyes from glare.
These glasses have blue-light blocking technology on their lens coatings and thus reduce digital strain and eye discomfort caused from digital screens. There are a wide range of blue light glasses offering different levels of protection. However, you must always look for the best-quality because your eyes deserve the best.
Why do you need blue light glasses?
The increasing use of smartphones, tablets, and computers have put our eyes under massive digital stress. Even if you don’t need glasses to correct your vision, it is always a good idea to wear glasses with blue light lens technology when using digital devices.
Not only this, these glasses are also said to improve sleep. Blue light lowers the release of melatonin levels in our body which causes sleep deprivations. Wearing blue light glasses before 3 or 4 hours of sleep can even help you get some good sleep.
Your eyes are the windows to your soul and thus need special care. Taking action when it is too late is not what we want for you. If you experience symptoms like dry eyes, blurry vision and eye stress, visit your optician for a quick examination.
Tips to reduce digital eye strain
Where wearing glasses will protect your vision, you can make some lifestyle changes and take the stress away from your peepers. Here is what you can do:
- While watching TV make sure the room is lit, even though softly.
- If you are reading a printed material, make sure that the source of the light is behind you.
- When working on a digital screen, take short breaks and look away from the screen. Do not forget to blink your eyes often to reduce the damage to your retina.
- While you must adjust the brightness of your computer as per your need, it is also important to avoid any overhead lights to prevent any additional glare. If you need some light to write or read, consider using a desk lamp.
We live in the digital age and thus using computers and laptops are part of our everyday activity. While we can’t avoid them, we can take up some measures to reduce the possibility of any potential damage.
