Blue light blocking glasses are everywhere. But here's what the research actually shows: blue light from screens isn't the primary cause of digital eye strain.
The real culprits are reduced blink rate, sustained near focus, and poor lighting conditions. When you stare at a screen, you blink up to 60% less than normal. That dries out your eyes and fatigues your focusing muscles.
Blue light lenses may help some people. But if you're uncomfortable, the answer is usually a proper evaluation, not a product.
Vision deserves accuracy, not assumptions.
