To test blue light filtering glasses, verify the closeness rating, which indicates effectiveness in blocking harmful blue light. Trusted manufacturers such as ROKA, BluBlox, and Gunnar offer products with high ratings (8-10). Seek certified glasses from reputable testing organizations like Underwriters Laboratories (UL) or Intertek, ensuring they meet industry standards like ISO 12312-1:2013 or ANSI Z80.3-2018, which guarantee safety and efficacy in reducing blue light exposure.
Protecting Your Eyes: The Importance of Blue Light Blocking Glasses and Closeness Rating
The Digital Age and Eye Strain
In today’s digital world, our eyes are constantly exposed to blue light emitted from electronic devices. This exposure can lead to eye strain, headaches, and even sleep problems. To protect your eyes, blue light blocking glasses have become increasingly popular. But not all glasses are created equal.
Understanding Closeness Rating
One important factor to consider when choosing blue light blocking glasses is the closeness rating. This rating measures how close the filters in the lenses come to blocking 100% of blue light. A higher closeness rating indicates that more blue light is blocked.
Significance of Closeness Rating
The closeness rating is crucial because it determines how effectively the glasses protect your eyes from harmful blue light. A low closeness rating means that the glasses allow more blue light to pass through, reducing their effectiveness. On the other hand, a high closeness rating ensures that more blue light is blocked, providing better protection for your eyes.
Choosing Glasses with a High Closeness Rating
When selecting blue light blocking glasses, opt for those with a closeness rating of 8 or higher. These glasses will provide optimal protection for your eyes and help reduce the negative effects of blue light exposure.
