Blue light blocking

Blue light blocking involves using lenses or screen filters to reduce exposure to high-energy blue wavelengths emitted by screens like computers, smartphones, and tablets. Blue light can contribute to eye strain, discomfort, and may disturb sleep patterns by affecting melatonin production. By filtering out or reducing this light, blue light blocking helps alleviate eye fatigue and promotes better sleep, especially during evening hours. These lenses or filters are designed to be transparent or lightly tinted, allowing most light to pass through while decreasing the intensity of blue wavelengths that can cause visual and circadian disruptions.
