Blue light blocking lenses are specially designed eyewear that filter out a portion of blue light emitted from digital screens, such as computers, smartphones, and tablets. This type of light can contribute to eye strain and discomfort, especially during prolonged use of electronic devices. These lenses are often coated with a special material that absorbs or reflects blue light, helping to reduce glare and improve visual comfort. Many people use blue light blocking lenses to enhance their viewing experience and potentially improve sleep quality by minimizing blue light exposure before bedtime.
