Red glasses don't let in blue or green light that interferes with the natural functioning of our biological clock. They serve to improve sleep quality as well as prevention and first aid for sleep problems and migrains. They help the body to maintain natural melatonin levels, which are essential for sleep quality. It is recommended to use the red glasses 90 minutes before bedtime. All common lighting fixtures we use at home contain a blue light component. This is necessary for our bodies during the day, but in the evening it disrupts our circadian rhythm and prevents us from getting a good night's rest. Red glasses block the blue and green spectral components even in strong light, and they also enhance the beneficial effect of the red component of the light spectrum on our body. Their beneficial effect usually becomes apparent after just few a evenings.
