Know the difference: Blue light and Computer glasses
Blue light glasses or computer glasses – what is the difference?
To set the record straight – “blue light glasses” is a fancy term for regular glasses with a blue light coating. The coating acts as a filter against blue light and protects the eyes from harmful light rays. Computer glasses, on the other hand, refers to the power range and usage of the glasses. Rather than a coating, computer glasses refer to the construction of the lens itself. They have specific strengths and measures that align with your working habits. You can also upgrade your computer glasses with a blue light coating so that it has the advantages of both blue light glasses and computer glasses.

Blue light glasses
Blue block glasses, anti-blue light glasses, blue light glasses... We have many names for the things we love. Did you know that blue light is everywhere in the world around us?
Why should I protect my eyes from blue light?´
Blue light rays have the shortest wavelengths with the highest energy, which means that more energy is delivered to the eye. When blue light is absorbed through your eyes your brain interprets it as daylight, which signals to the brain and the rest of the body that it’s time to be awake. This means that in the nighttime, the blue light from screens acts as artificial daylight – disturbing your circadian rhythm and all the processes that come with it.
During the nighttime, the body secretes a hormone called melatonin that promotes sleep and initiates a series of biological processes at specific times of the day. That's why at night a specific signal is sent to your brain, which then informs your body to secrete melatonin that makes you drowsy.
The natural processes related to the contrast between day and night is disturbed by artificial light sources such as blue light from our screens. Research shows that prolonged lack of sleep can negatively affect our immune systems, making us prone to diseases such as cancer and rising blood pressure.
How can I protect my eyes from harm?
As the world continues to technologically develop, it's pretty obvious that it's difficult to avoid artificial light. It has become a permanent part of our everyday lives and is crucial for our work and communication. However, there are active changes we can make to our routines to address the problem. At night, avoid harsh lighting and use dimmed or even red light, which is less likely to alter your circadian rhythm and suppress melatonin. If you work a lot from a screen you can use blue light filtering glasses. Wear them when you sit in front of your computer or with your smartphone, especially in the evening. Take care of your eyes because they don't just help your vision, but also your overall health, sleep and wellbeing!
Occupational glasses, degressive glasses and screen glasses are all terms that describe glasses with strengths specifically measured for screen use. There is a range of different computer glasses, that in different ways help seeing clearly in your workspace. Computer glasses can be further geared with blue light coating, to protect your eyes from harmful blue light. Depending on your personal measures and work habits, here are a short explanation of 3 types of computer lenses:
3 common types of computer lenses
Single-strength computer glasses: The single-strength computer glasses are not progressive, which means they are set for one chosen distance. They work for most people who sit at the same spot or at least at the same distance all day. They are also good for people who don’t have a prescription on distance, so they can just take their glasses off when not working on screen. The single-strength ones are also a cheaper alternative to the progressive ones.
Mid-range progressive: Mid-range progressive lenses are for those who want a bit more range flexibility. If you for instance work as a receptionist or attend many physical meetings, you should opt for the room-progressive ones. You will see clearly on your screen as well as up to 4 meters ahead. This means they will work for both screen distance and presentation distances. Because the distance strengths take up space in the lenses, you compromise with the quality of the near sight, however, they work well for dynamic work habits.
