So there is a lot of talk about the blue light right now and the need for Blue Light Protection Glasses. But, does Blue Light Glasses help? Or is it just marketing hype? That’s why in this blog we’re answering – Do Blue Light Protection Glasses work?
The first major thing that you will hear about blue light and the need for Blue Light Glasses is that blue light affects our sleep and that is true! Blue light has been found in studies to affect retinal cells in the back of the eye which then speak to the pineal gland in your brain which produces Melatonin which is known as the sleeping hormone. The presence of Melatonin helps improve your overall nightly sleep, which of course affects different health aspects including affecting memory and that is why people who do not get very good sleep have increased risked chances of things like early dementia and Alzheimer’s. The blue light affects because most of the blue light you ever experience in your life comes from the Sun and so staring at your computer screen or your cell phone for a long period, especially in the evening kind of acts like staring at the sun early in the morning, tells your brain to wake up and to stay alert! That means the people who spend a lot of time in front of digital screens are at higher risk of diminishing the melatonin production and therefore risking having poor sleep, which is important for younger individuals such as children who are starting to use more digital products in their whole learning regiment; whether they’re doing homework in front of computers, staying up all night writing a paper or learning on something like an iPad.
For this reason, Blue Light Glasses are recommended for the people who spend a lot of time in front of digital screens, however, overall most eye care professionals will recommend that people should try to reduce the amount of screen time use, especially in the later evening. Try not to use any sort of digital screen at least 2 hours before going to bedtime. Also, if your digital device has a blue light or night time mode, turn that software on. Studies have found out that those apps do reduce the amount of effect that blue light can have on your melatonin production, however, it’s not 100% and so again people who are spending a lot of time in front of computer screens should consider using Blue Light Glasses. The second big thing you will hear about Blue Light Glasses is the reduction of eye fatigue, eye strain also known as digital eye strain or computer vision syndrome, which can lead to things like headaches and as far as the scientific validity for these statements, it is very mixed. Most studies have found out that people do benefit from using these Blue Light Protection Glasses to reduce eye strain, however, it depends on the lifestyle of a person.
Overall, Blue Light Protection Glasses are something you should look forward to if you’re a heavy digital gadget user/student or an IT professional and are planning to upgrade your frame and your glasses. This is something that is an investment and not an expense.
