Products for a Healthier Life
Welcome to lowbluelights.com.
We have special glasses and lights that can improve both your sleep and your health. Your body produces the important hormone melatonin, the so-called sleep hormone. Increasing your body’s melatonin production can improve your sleep. Melatonin is produced by your pineal gland, normally only when you are in darkness. Using artificial light in the evening before going to bed shuts down melatonin production.
Blue rays in ordinary light are the problem
Only the blue component of light shuts down melatonin production.
We have glasses and lights with filters that eliminate only the blue component of light. Using them for one to three hours before retiring allows melatonin to be produced naturally. While using them, the remaining colors of light allow you to read, watch television, etc.
Money Back Guarantee
If wearing our glasses does not improve your sleep, return them within 30 days and we will refund your money.
What one mother wrote to us:
"My husband and I want to thank you for the miracle that you have brought to our family. We have four great kids, and our youngest had a terrible time falling asleep at night. Dr. Gonzalez suggested the glasses, and our 6 year old has been wearing them now for over two months. We noticed a big difference in just 3 days! Prior to using the glasses, our youngest could not fall asleep before 11:30 pm, and he slept until at least 10:30 in the morning. Waking him for school was literally like waking the dead. It was impossible. Now, he falls asleep by 8:30 pm with ease and is eager to wake up for school at 7:00. He is energetic all day.
What a gift you have given to us. My kids are in 4 different schools, and I have started to recommend the glasses to various administrators and teachers because it is a shame for other kids to suffer.

Benefits of controlling blue light.
The main conditions where controlling blue light entering the eyes can improve wellness include improved sleep, improved control of mood for people with bipolar disorder, and avoiding depression during pregnancy and after the baby arrives (postpartum depression). Some young people with ADHD have also reported reduction in symptoms that resulted from improved sleep when controlling light with amber glasses (that block blue light) in the time preceding bedtime. One ADHD mother reported her son awakening feeling happy for the fist time in his life after using blue light blocking glasses in the evening to help him fall asleep at an earlier hour.
A number of people with longstanding insomnia (persistent insomnia) have reported being able to develop a normal sleep pattern by using amber glasses that block just the blue light. One doctor gave glasses that block blue light to three of her patients with histories of persistent insomnia. She reported being in awe that all three were now sleeping like babies. Thousands of amber glasses that block blue light have been sold to people with sleep problems through this website with a money back guarantee. About 85% of those with insomnia find the amber glasses help them sleep. The amber glasses work by blocking the blue light that cause suppression of melatonin, the sleep hormone. The amber glasses can also produce a shift in the circadian rhythm to an earlier hour. For people who suffer from delayed sleep phase syndrome (DSPS) in which they are used to staying up most of the night, blocking the blue rays may help them advance their circadian rhythm. Some people never produce much melatonin. Those people may not get a benefit to their sleep by wearing blue light blocking amber glasses. Most people with sleep problems who purchase the blue light blocking glasses find they begin seeing a benefit within a few days. It may depend on how far they need to shift their circadian rhythm. Stimulating an earlier flow of melatonin by blocking blue light in the evening is accomplished by advancing the circadian rhythm (setting the internal clock to an earlier hour). This is similar to accommodating to a time zone change (jet lag) and requires a day or two for each time zone change. If you are used to going to bed at 1:00A.M., and want to get to sleep at 11:00 P.M., it may take at least two evenings of putting on the blue light blocking glasses at 9:00P.M. Moving the circadian rhythm an hour per night may work better than trying to move back the internal clock all at once.
Reduced Risk of Cancer
Numerous studies with both animals and people show that increasing the time when melatonin is present in the body can slow down or prevent cancer tumor growth. Other studies show that blocking blue light with amber glasses is the equivalent of being in darkness as far as melatonin production is concerned. The term virtual darkness has been used to describe the result of wearing amber glasses that block blue light. One study provided human blood to infuse human breast cancers grown on the backs of rats. When the blood contained melatonin the cancers did not grow or grew slowly. When the blood did not contain melatonin the cancers grew rapidly. The blood with melatonin was obtained from women volunteers during the night when they were in darkness. The blood without melatonin was either drawn during the light of day, or drawn during the night, when the volunteers were keep under lighted conditions.
In animal studies, two groups of rats were raised under either a long night (16 hours) (one group) or raised under a long day of 16 hours, the second group. When injected with a carcinogen (a chemical that causes cancer) the long-day rats were found to have little melatonin and the cancers grew rapidly and killed the rats. The long-night rats were found to have more melatonin. Most of them did not develop cancer and those that did experienced slow growth of the cancer.
Thousands of nurses participated in an ongoing health study. One result of the study was the finding that nurses who work night shift for a long time have about twice the rate of breast cancer as nurses who never worked night shift. The theory is that working at night under lighted conditions reduces the amount of melatonin produced. A related study measured a metabolite of melatonin in first morning urine over a period of time. Years later the breast cancer rate for those who had the highest melatonin metabolite was found to be half of the rate for those that had the lowest concentration of melatonin metabolite.
Another theory places the emphasis on the disruption of the circadian rhythm as the cause for increased cancer rate among night shift workers. It appears the amber glasses may help in establishing a uniform circadian rhythm even for night shift workers. Rather than wearing the amber glasses in the evening before going to bed, they may wear them in the morning before going to bed. The circadian rhythm may be kept constant by putting on the glasses at the same time every day, whether in the evening or morning.
Some have suggested nurses working at night (and all nighttime workers for that matter) should wear amber glasses to block blue light to preserve melatonin. The problem is that melatonin makes people feel like sleeping. No one wants a nurse who is half asleep. The proper use of amber glasses that block blue light is to shift the circadian cycle to a much later time and to wear the amber glasses for a few hours before going to bed during the day. That way the melatonin flow will occur while sleeping.
All women should be concerned about breast cancer and other cancers that are related to the hormone estrogen. These include ovarian cancer, endometrial cancer, and cervical cancer. Melatonin has been shown to fight cancer in at least three distinct ways. Melatonin interferes with the way that estrogen promotes cancer growth. Melatonin is a powerful antioxidant that destroys damaged cells that might become the start of a cancer. Melatonin interferes with the metabolism of linoleic acid (cancerís favorite food) by cancer cells. If amber glasses that block the blue light that suppresses melatonin are worn for a few hours before bedtime, the duration of the flow of melatonin can be maximized to the 10 or 11 hours known to be possible. Alternatively, light bulbs may be used that block blue light for a few hours in the evening before going to bed in darkness. The combination of those hours of virtual darkness combined with the hours in real darkness can equal to the 10 or 11 hours during which melatonin can flow. If light bulbs that block blue light are used they obviously need to be in every lamp being used.
While Pregnant and Postpartum
Another important use of amber glasses that block blue light and light bulbs that block blue light is in connection with pregnancy. When women are pregnant they tend to have sleep problems. Most pregnant women find they need to get up frequently during the night. If they turn on a light it will begin suppressing the production of melatonin. Without melatonin it may be difficult to fall asleep again. This is at the root of some sleep problems. By wearing amber glasses that block blue light for a while before bedtime, they can start the flow of melatonin before trying to sleep. The melatonin helps them fall asleep quickly and sleep more soundly. By wearing the amber glasses that block blue light when they get up at night their melatonin flow is preserved and they can go to sleep again very easily. Their circadian rhythm is not disrupted. Some pregnant women suffer from anxiety. Because melatonin has a calming effect on the body, maximizing the flow of melatonin may be helpful. Some pregnant women tend to become depressed when they have trouble sleeping. The use of amber glasses that block blue light may help these women sleep better and reduce the likelihood of becoming depressed.
When the pregnancy ends with the delivery, avoiding exposing the eyes to light at night by wearing glasses that block blue light is even more important. Light bulbs that block blue light are ideal for use in the nursery. Once in the nursery with light bulbs that block blue light the amber glasses are not necessary. A study done with women suffering from postpartum depression found they overcame their depression more quickly by using the amber glasses that block blue light and nursery lights that do not produce the blue light that causes melatonin suppression. When being awakened by the baby during the night they put on their amber glasses before turning on any lights. This way they avoided cutting off the flow of melatonin. They avoid disrupting their circadian rhythm. The testing of the amber glasses with women who were suffering from postpartum depression (sometimes called the baby blues) helped them recover, but it makes more sense to try to avoid depression by starting the use of amber glasses and light bulbs that donít produce blue light during pregnancy (or before becoming pregnant) to avoid becoming depressed while pregnant and after the baby is born (postpartum). Preserving the circadian rhythm during pregnancy and postpartum helps avoid anxiety and depression. It may also reduce the risk of breast cancer.
