Advice
- The price of blue light blocking glasses does not always correspond to its effectiveness. However, glasses that block at least 30% of blue light and have anti-glare coating rarely cost less than $40.
- If the manufacturer refuses to provide a report or you have doubts about its accuracy, take your glasses to your ophthalmologist or an independent company that has a laboratory spectrometer. They can tell you how much blue light is blocked and at what frequency. [9] X Research Source
Warning
- Some companies offer “blue light pens” (small flashlights that shine blue light) that you can shine through your lenses to demonstrate that their glasses are resistant to blue light. However, these pens typically emit violet light (located right next to blue on the spectrum) rather than blue. This marketing tactic is often seen as deceptive. [10] X Research Source
