The device you are reading this blog on is illuminated by a very specific type of light known as blue light. This short wavelength of light may not seem like much to you, but as we rely increasingly on devices that use it, researchers are spending greater amounts of time investigating the potential side effects. Unfortunately, many of them are not good. For instance, blue light can disrupt your body’s natural circadian rhythm, or internal clock, at night, leading to sleep disruptions. It may also be linked to the development of eye diseases such as age-related macular degeneration in the long run. Of course, we understand that it may be impossible to fully escape electronic devices such as your computer or phone, but there are precautions you can take. Here are four ways that you can help reduce your blue light exposure:
Blue Light Blocking Glasses
Blue light blocking eye glasses are becoming increasingly available to help reduce the negative effects of this light form. With lenses designed to filter out blue light, these glasses may just help protect your eyes from future problems and help prevent sleep disruption. While the jury is still out on how effective these glasses are, they may just be worth looking into for those who spend several hours per day in front of a screen.
Blue Light Screen Protectors
You likely already have a screen protector on your phone, so why not use one that can also reduce your blue light exposure? Products like Ocushield serve double duty by accomplishing both. You may even find it preferable to your phone’s own settings (like Apple’s Night Shift), because it doesn’t interfere with the color quality of your screen.
Dim Red Light Bulbs as a Blue Light Alternative
Electronics aren’t the only source of blue light we encounter day-to-day. Those energy efficient, LED light bulbs are a source too. This means that even if you aren’t looking at a screen prior to bed, your bedroom lights may still be causing a sleep problem. Consider using dim, red light bulbs at night to give the room a soft glow that won’t bother your eyes or your sleep.
Blue Light Reducing Apps and Software
Your phone may use a similar setting already. If not, there are apps and software available that allow your device to mimic the natural shift of sunlight. Again, this is an option that may help you sleep better at night by minimizing disruption of circadian rhythms. However, long-term use may also help protect your eye health by reducing your overall blue light exposure.
There are more threats to eye health than many realize. Fortunately, the dangers of blue light have been well-publicized, prompting many to take action now and protect their eye health into the future. Use the products above to help control your own blue light exposure, and always maintain regular eye exams to keep your vision strong and healthy.
