Glasses with blue filter feature specialty crafted lenses that claim to filter or block out the blue light that comes from digital screens. Their lenses are usually advertised with some lofty claims of protecting your eyes from eye strain and helping reduce potential damages to your retina from extended exposure to blue light.
Will Glasses with Blue Filter Solve Eye Strain?
This may come as a surprise to you but most eye problems due to digital screens are not really because of the blue light itself.
According to experts, most people suffer from eye discomfort from the digital screens. However, many of the problems actually belong to the term called CVS or computer vision syndrome. It is also sometimes called digital eye strain. Among its symptoms include the following:
- Blurred vision
- Burning eyes
- Difficulty concentrating
- Dry eyes
- Hard time of keeping your eyes open
- Itchy eyes
- Sensitivity to light
- Shoulder and neck pain
- Watery eyes
CVS is an extensive range of eye discomfort and strain problems. Your eyes constantly shift focus and move as you look at the screen. Aside from this, the contrast and glare might prove to be too much for your eyes. This means that even if you might be suffering from eye irritation from a long and tiring day at work in front of your computer, the blue light itself might not be the direct cause of your eye discomfort.
Every time you stare at your digital device or screen for a long time, you don’t blink as often as you normally should, and this is what makes the cornea irritated and dry. If you have your eyes focused on something hat is close up, such as a screen or a book, your eyes will become contracted and strained, and this is what leads to eye discomfort. However, your eyes can relax when you try looking ahead to a certain distant object.
Is Wearing Blue Light Glasses a Bad Idea?
Even if glasses with blue filter are not really that effective when it comes to warding off digital eye strain, wearing them wouldn’t cause you any harm. Experts also claim that it wouldn’t be harmful at all to wear these glasses (https://www.crulle.de/) throughout the day.
