Staring at screens is a daily necessity for many, leaving our eyes feeling dry and fatigued. But is blue light really to blame for all this discomfort?
In today’s digital age, screen time is almost unavoidable, especially if your work involves long hours on a computer, tablet, or smartphone. While some worry about the impact of blue light on vision, experts suggest it’s more about the eyestrain from focusing intensely on screens. Digital eyestrain, or computer vision syndrome, may not cause permanent eye damage, but it can lead to uncomfortable symptoms like dry eyes and headaches.
Dr. Ashley Hayden, a retired ophthalmologist, points out that screens emit more blue light compared to other colors in the spectrum. This exposure is why some people feel their eyes are overworked after a day filled with spreadsheets or back-to-back virtual meetings. However, it’s crucial to understand that the blue light from your devices isn’t harmful like sunlight. The real issue stems from how our eyes focus more intensely on digital screens.
Dr. Danielle Richardson, an optometrist, highlights that blue light focuses in front of the retina, not on it, which makes our eyes work harder. Symptoms like blurry vision and sore eyes often surface when the eye muscles tire from focusing too closely on screens for prolonged periods.

Although many suggest blue light glasses as a solution, Dr. Richardson mentions that they are not a magical fix. Instead, the key to reducing eyestrain involves a mix of lifestyle adjustments. These include stepping away from the screen, ensuring you have the right prescription for your glasses, and blinking more to keep eyes moist.
Practical tips for alleviating symptoms also involve adjusting screen brightness, taking breaks to look at distant objects, and using eye drops to maintain moisture. Annual eye exams can also help, as they ensure your prescription is current and identify any other underlying issues.
While blue light glasses might assist, they should be seen as one part of a broader strategy to manage digital eyestrain. Dr. Richardson advises combining them with changes like getting enough natural light exposure and setting screens at an arm’s length distance.
Ultimately, while blue light glasses can play a role, real relief from digital eyestrain comes from combining them with mindful screen habits. These practices will not only make your workday more comfortable but also support long-term eye health.
