Summary:
- Blue light glasses are designed to filter out or block blue light wavelengths emitted by digital screens, such as smartphones, computers, and TVs.
- The purpose of blue light glasses is to reduce eye strain, headaches, and disruption to the body's natural sleep-wake cycle caused by exposure to blue light before bedtime.
- While some studies suggest blue light glasses can be beneficial, the effectiveness of these glasses is still debated, and more research is needed to conclusively determine their impact on eye health and sleep quality.
