Blue light glasses may help with eye strain, but the science is still mixed. Large-scale studies suggest screen-related eye strain is more likely caused by reduced blinking, prolonged near-focus, and screen glare than blue light itself. That said, many blue light glasses include anti-reflective coatings that cut glare and may ease that end-of-day eye fatigue. They can also nudge you toward better screen habits overall. So while they're not a guaranteed fix, a good pair can still make screen time more comfortable.
