Blue-blocking Glasses To Improve Sleep And ADHD Symptoms Developed

Blue-blocking Glasses To Improve Sleep And ADHD Symptoms Developed

Scientists at John Carroll University, working in its Lighting Innovations Institute, have developed an affordable accessory that appears to reduce the symptoms of ADHD. Their discovery also has also been shown to improve sleep patterns among people who have difficulty falling asleep. The John Carroll researchers have created glasses designed to block blue light, therefore altering a person's circadian rhythm, which leads to improvement in ADHD symptoms and sleep disorders.

How the Glasses Work

The individual puts on the glasses a couple of hours ahead of bedtime, advancing the circadian rhythm. The special glasses block the blue rays that cause a delay in the start of the flow of melatonin, the sleep hormone. Normally, melatonin flow doesn't begin until after the individual goes into darkness.

Studies indicate that promoting the earlier release of melatonin results in a marked decline of ADHD symptoms.

Better Sleep/Disease Prevention/Depression Relief

Major uses of the blue-blocking glasses include: providing better sleep, avoiding postpartum depression, preventing Seasonal Affective Disorder and reducing the risk of cancer.
