What Does Blue Light Glasses Do to Your Eyes ?

Should you invest in a pair of blue light glasses? Do they benefit your eyesight? What do they do exactly? We have the answers to all your questions right here.

Before we begin, take a moment to think about how many times a day you look at a screen, be it a phone, laptop, or TV screen. Once, twice, thrice… if you think about it, it can’t be counted on the fingers of your palms because it exceeds way beyond 10 times a day. From the moment we wake up to switch off the alarm on our phone, to the moment we go to bed at night, to set up the alarm on the phone for the next day, and all the time in between, we are constantly exposed to screen time. 

It is due to this extreme amount of exposure; blue light glasses have been specifically created to filter out harmful UV rays produced from all digital screens; to preserve our eyesight. If you want to get your hands on a pair, luckily, you can sit in the comfort of your home while browsing through blue-light-blocking glasses online.

The Blues

Blue light doesn’t appear blue to the naked eye. It is a part of the visible light spectrum with the shortest wavelengths and highest energy. It is referred to as high-energy visible (HEV) light. It all sounds harmless, right? But the problem arises because the human eye does not block blue light well. Blue light often passes through the cornea and lens and reaches the retina at the back of the eye. This constant exposure can lead to eye strain and increase the risk of macular degeneration. 

Apart from damaging the retina, blue light also affects the sleep/wake cycle (the circadian rhythm). In the morning, the blue light from the sun helps us feel more energized and awake. While this is good during the day, as evening sets in and night falls, exposure to blue light throws off our sleep cycle. We are all guilty of scrolling through social media, binging on a Netflix series, or working late into the night, thus, disrupting our natural sleep patterns by unnaturally exposing ourselves to blue light. These practices delay the release of melatonin (the hormone responsible for making us feel sleepy). This hormone naturally starts circulating in our system a few hours before bedtime. An interruption in this process disrupts our sleep pattern and our quality of sleep. 

The Good News

So, what do these glasses do to your eyes? Blue light lenses filter out blue light by blocking the emission of a specific range of wavelengths. Also, the lenses are created for reducing digital eye strain and avoiding any disruption in the circadian rhythm cycle. Thus, promoting good sleep and overall well-being.

  • Overexposure to blue light causes stress hormones to become abnormally elevated, resulting in anxiety and depression. Blue light glasses can help eliminate the damaging effect on your mental health.
