How to Know if Your Blue Light Glasses Work: 1 Minute to Discover the Effectiveness of Blue Light Glasses

Blue light glasses are designed to filter or block blue light emitted by screens, LED lights, and electronic devices, helping to reduce eye strain and improve sleep. But how do you know if your blue light glasses are actually working? To determine their effectiveness, start by checking if there are visible changes in your daily screen use experience. One common sign is a reduction in eye fatigue or dryness, especially after long sessions at your computer or smartphone. Additionally, you may notice fewer headaches or less squinting while using digital devices.

Some blue light glasses have a slightly yellow or amber tint to the lenses; if yours do, try holding them up to a white background or bright screen—the tint should filter out some of the blue hue. For a more objective test, you could use online blue light test images or apps that display blue and other colors; ideally, blue regions should appear dimmed or altered through the glasses. Another reliable method is to shine a blue LED light through the lens onto a white surface: if the spot appears significantly less blue or changed in color, the glasses are blocking some blue light.

As a designer, I test the comfort and visual clarity of blue light glasses in environments with both natural and artificial lighting. Comfort is essential, especially when I'm planning a workspace with computer use in mind. Proper indoor lighting and ergonomic room layouts work hand in hand with quality blue light glasses to create an eye-friendly work zone.

Tips 1:

If your symptoms persist even while wearing the glasses, consider checking the lens specifications for blue light filtering percentage, or consult your optometrist for more advanced options.
