Yes, blue light glasses help minimise the digital eye strain put on by looking at screens all day.
Blue light reduces our production of melatonin (sleep hormone) which help us sleep at night. Inevitably, this causes us to stay awake longer at night and excessively stare at our screens. This will not only disrupt our sleep cycle but also lead to eye strain. For this reason, you will find blue light lenses help with both sleep and digital eye strain.
