Blue light-blocking glasses are designed to filter out or block the blue light emitted by digital screens, such as phones, tablets, and computers. Many people experience eye strain, dryness, and sleep disturbances due to prolonged screen exposure. Blue light-blocking glasses can help alleviate these symptoms and provide a more comfortable viewing experience.nnIf you spend a significant amount of time in front of digital screens or have trouble sleeping after screen use, blue light-blocking glasses may be beneficial for you. Consult with your optometrist to determine if these glasses are suitable for your specific needs.
