What Are Blue Light Glasses And Do You Need Them

ByWowThankYou

With the increase in the number of people working from home, our collective screen time is on the rise. We all know that working on screens for long periods of time can cause our eyes to become tired and strained, but it doesn’t change the fact that most of our work is on screens!

Blue light glasses have been marketed as a way to protect your eyes from eye strain. The question is, do they really work?

What are blue light glasses?

Blue light glasses are glasses with lenses that have been specially made to filter out the blue light that is given off by the screens on our computers and other digital devices. They are also designed to minimize screen glare, which is a contributing factor to eye strain.

Do they really work?

There needs to be more research to prove conclusively whether blue light glasses work, however, the existing research seems to indicate that they do, and anecdotally a lot of people seem to be seeing a benefit from using them.

Studies have shown that:

  • Blue light from light-emitting diodes (LED) could have long-term health effects, including eye strain.
  • The blue light emitted by LED could interrupt the body’s production of melatonin, which is the hormone that helps you to sleep. Your body produces melatonin throughout the day, and once the amount of melatonin in your body reaches a certain level, your body knows that it is time to sleep. If melatonin production is interrupted, this means that your body doesn’t know that it’s time to sleep, which can result in insomnia.
  • Using blue light glasses for a few hours before you go to sleep could help you to fall asleep more easily.

One woman tried out blue light glasses for a week and found that she saw some benefits. Before trying the glasses she often found that her eyes were red and tired by the end of the day. She saw an improvement in this area from wearing the blue light glasses.

If you would like to give blue light glasses a try, there are a range of options available on Just-glasses.co.uk. Unlike traditional blue light glasses, which can be quite bulky and not very nice to look at, the range is designed to be stylish, so that you can wear them and actually enjoy the way they look.

Another reason that blue light glasses are so effective is that they encourage you to become more aware of how much time you are spending looking at screens. If you have to put the glasses on each time you glance at your computer or pick up your phone, you soon become aware of how often you are doing this. This can encourage you to take more regular breaks.

Regular breaks are an important part of looking after your eye health. The recommendation is that every 20 minutes you take a break for 20 seconds, to look at something 20 feet away. This idea (known as the 20-20-20 rule) gives your eyes a chance to rest.
