Yes, blue light glasses can be effective in reducing eye strain from screen use. They work by blocking or filtering out the blue light emitted by digital screens, which is believed to cause eye fatigue and disrupt sleep patterns. While not all blue light is bad, overexposure, especially before bedtime, can impact sleep quality. For best results, combine the use of blue light glasses with other eye strain reduction strategies, such as taking regular breaks using the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds).
