Product FAQs
Q: Will using LBL Sleep Glasses or filters change how things appear?
LBL glasses and filters are used to remove only the blue wavelengths of light transmitted through them. True blue objects viewed through our glasses will appear black. Lighter shades of blue will appear as various shades of grey. Other colors, i.e., green, yellow, orange or red, will not change appearance.
Q: What is the difference between using LBL glasses versus using our filters?
Simply put, LBL glasses are the ultimate solution in preventing the harmful effects of nighttime blue light. In the hours leading to bedtime your eyes must be in a 100% blue-free environment otherwise melatonin production will not occur. Our glasses create a virtual darkness which allows normal nighttime activities without the harmful effects of blue light. Although LBL filters are very effective, they must be used in either complete darkness or while under 100% blue-free light sources. If our sleep glasses are used, our bulbs and filters are not necessary. Our flashlights and nightlights are a great way to navigate around the home if you need to be up during the night. If our filters are used, you must be in complete darkness or in a room illuminated with LBL bulbs, otherwise benefits will not be gained. If trying to establish a 100% blue-free environment at night without the use our Sleep Glasses, it’s imperative that all light sources be from our 100% blue-free light bulbs and all screens be covered with our filters. Encountering any light source that is not blue-free will disrupt the benefits gained earlier and will cause melatonin-suppression.
Q: Can I use my LBL glasses 24/7?
The major reasons for using LBL glasses are to maximize melatonin production and improve sleep. By wearing the glasses for several hours in the evening before going to bed, melatonin can be produced by the pineal gland for up to the 11 to 12 hours. Exposure to blue light especially early sunlight and throughout the day is very healthy. Therefore, except in special cases when blue light exposure may cause eye problems, wearing LBL glasses 24/7 is not recommended.
Q: Can I keep my LBL filter on my device 24/7?
Some individuals find eye strain is reduced with LBL filters on their computer or TV screens, regardless of the time of day. However, exposure to blue light during the day is beneficial, especially in the early morning when it resets the body’s circadian clock. Though no harm will arise from having the filters on your screen throughout the day, it may be more beneficial to use them only in the evening hours.
Q: How should I clean my eyewear?
LBL glasses should be cleaned using a mild liquid dish detergent and warm water. Rinse well to remove any soap residue and then allow the lenses to air-dry. Cleaners that have alcohol or any other harsh chemicals should be avoided.
Q: How should the filters be cleaned?
A small amount of mild dish detergent on a soft cloth works quite well while holding the filter under warm water. Gently wipe both sides, keeping the filter relatively flat in the palm of the hand. Rinse well to remove any detergent residue. Warm water is the key. Cold water will stiffen the filter; hot water will make it flimsy. Allow the filter to dry flat between a pair of paper towels and always store it in a flat position.
Q: What are the differences between the acrylic and vinyl filters?
All LBL filters are removable and adhesive free. The amber filters are made of rigid acrylic approximately 1/8″ in thick. They have the same transmission as the LBL glasses and block all melatonin- suppressing light below 530nm. Because of their thickness, acrylic filters do not allow any touchscreen functions. The large BlueShield filters are made of the same vinyl material as the small iPhone, IPad, tablet & smartphone filters. The 14mil thick vinyl filters block all melatonin-suppressing wavelengths below 510nm and allow touchscreen capability.
Q: Are red nightlights better than amber nightlights?
Red nightlights can be used to avoid suppressing melatonin. The main advantage to using amber nightlights is that amber light is closer to the human vision peak sensitivity than red. Thus you’ll be able to see better with amber light without suppressing melatonin.
Q: How and why are LBL filters used on hand-held devices?
The LBL iPad, iPhone, smartphone and tablet filters have a patent pending design which allows them to be applied and removed without using any adhesive or leaving a residue on a device’s screen. Their 14mil thick vinyl material has excellent clarity and allows full touchscreen capability. They are designed to be used in the evening prior to bedtime or while in bed and are easy to remove and store when not in use. LBL filters are the only filters on the market today that block 100% of the blue light wavelengths shown to be responsible for the body’s suppression of melatonin.
Q: How do LBL vinyl filters differ from others that are on the market?
LBL iPad, iPhone, BlueShield and design-it-yourself filters are made of a durable vinyl that are flexible, washable and require no adhesive allowing them to be easily removed when not in use. These filters are approximately 14mil thick allowing full touchscreen capability. Most importantly they block all melatonin-suppressing blue light below 510nm. Many competitors claim their filters block blue light without changing the screen appearance, however, this is impossible. When areas of an illuminated screen appear white or blue, blue light is being transmitted. Plain & simple-if a screen’s appearance is not altered, blue light is not being blocked.
Q: How should LBL vinyl filters be used?
LBL vinyl filters have a patent pending design. These 14mil thick filters are made of a durable vinyl material which is adhesive-free, washable and removable. The filter will attach to any glossy surface and should never lose its strong adherence property. They have excellent clarity which allows all normal activities such as reading, texting and gaming. They are designed to be used in the evening either in complete darkness or under blue-free light sources. These removable filters can be stored off the device when not in use.
Q: May wearing LBL glasses help alleviate severe headaches?
A user of LBL glasses reported the following: “As one who suffers from bouts of cluster headaches and debilitating migraines, I can personally attest to the positive benefits gained by using LBL blue-filtering eyewear. Whenever the sensation of a headache begins to set in, I always reach for my LBL Novelists. These glasses block what I feel to be a major contributing factor to my headaches–the blue light from either ambient light I’m under or from the screen that I’m using. In my opinion, they are your most comfortable style. I’m convinced I benefit from their use and always have them with me. Once the headache pain subsides, I remove them.”
Q: What makes LBL products better than similar ones on the market?
There are many knock-off products on the market today that purport to have the same melatonin-enhancing features as LBL glasses, bulbs and filters. The other products claim to block enough blue light, but the results of laboratory tests indicate that they do not. LBL products are guaranteed to block all of the melatonin-suppressing blue light.
Q: How do LBL lamps differ from yellow “bug lights”?
LBL light bulbs are specifically designed to block the blue light wavelengths that suppresses melatonin. There may be other lamps that block enough of the blue that suppresses melatonin, but from what we have tested in the laboratory, many of them do not. Our bulbs are guaranteed to block wavelengths up to 530 nm. The light that suppresses melatonin is from about 410 nm (deep blue almost purple) to 530 nm (Blue-green), peaking in a bell-shaped curve at approximately470 nm (pure blue). Several top lighting manufacturers have introduced nighttime bulbs that have lower blue light output however these bulbs still emit enough blue light to cause melatonin suppression. Only LowBlueLights bulbs are guaranteed to be 100% blue-free.
Q: Is it safe to use LBL compact fluorescent or CFLs?
The only question about CFL safety is the amount of mercury if a lamp should break. The actual amount of mercury is a few milligrams. This is an extremely small amount. The EPA suggests people not use a vacuum cleaner to clean up if a lamp breaks but rather sweep up the remains and dispose of them along with other household trash. Therefore, we do not consider them a danger. For those concerned with mercury clean-up and governmental disposal procedures of CFLs, please consult the EPA procedures found here: https://www.epa.gov/cfl/cleaning-broken-cfl. These procedures are intended for US residents only. Please consult your own country’s safety guidelines.
Q: Why are there similar glasses, bulbs and filters less expensive than LBL glasses?

Sleep FAQs
Q: How can I fall asleep more easily?
A: By using Low Blue Lights or LowBlueLight eyewear in the hours before bedtime, your melatonin level will rise. Just be sure not to expose your eyes to any kind of light that may contain blue wavelengths, such as white light, without using the LowBlueLight products. This may negate the effects.
Q: What feedback have you received from customers?
A: Following are some responses we have had from customers:
From an M.D. sleep specialist:
I just sent an e-mail to Dr. Carome letting him know that I have given away the 3 glasses that he gave me, and all 3 patients are now sleeping like babies!! I am in awe!
From a M.D. sleep specialist:
I wanted to share with you that my most challenging insomnia patient was able to sleep a full 5-6 hours consecutively every night he used the glasses. He wants to buy all lights and filters for his house!
From a student:
My experiment with the glasses turned out remarkably well. I would put the glasses on one hour before bedtime eachNight. Not only did I fall asleep within 10 minutes ofactually trying to fall asleep, I also did not wake up inthe middle of the night or only woke up once. This is quitean improvement from my normal sleep pattern.
From a person with DSPS:
Your eyewear has made a tremendous difference in my life in only 4 weeks! I am now getting to bed by midnight each night for the first time in 11 years. I have struggled with delayed sleep phase syndrome all of my life. I felt the effects from wearing your glasses immediately. I started having vivid dreams and slept very soundly. I woke up early each morning and was ready for bed earlier each night. I actually found myself taking a walk at 8:00A.M. this week. Amazing for someone who never used to even wake up until noon!
When I ordered these glasses, my husband referred to them as my “Quack Quack glasses” because he figured it was just yet another New Age product from a “bunch of quacks” who made promises that they could not deliver. He does not call them that now. Now we call them my “Miracle Glasses.”

From a very satisfied customer:
Kay had to surrender her glasses to our daughter this weekend. Kay would need to wrestle my glasses from my cold dead fingers! We will be placing another order this week.
Date: Thu 9 Nov 10:28:36 EST 2006
Thanks for the inquiry. Yes, the glasses have been helpful…I try to be rigorous about wearing them, but it is difficult. Coincidentally, I have changed medications ( not sleep meds) and that has helped sleep as well. Hard to say how much is each with several determinants.
Date: Thu 16 Nov 15:01:56 EST 2006
I use these for reading prior to bed time and find I get sleepy and am able to initiate sleep at a more appropriate time. If I awake in middle of night and have trouble falling asleep again, I wear the glasses and read, rather than worry about sleep, and find I return to sleep more easily than if I read w/o the glasses.

My husband used the glasses when he was having trouble relaxing before bed. He said they were very soothing and seemed to help. However, he now falls asleep fairly easily and has stopped using the glasses. However, when just asked he said he would like to start using them again..

When i remember, I use them, especially with computer monitor. I think they help, but not dramatically.
Date: Sun 26 Nov 19:37:34 EST 2006
i do find the glasses to be beneficial. they have helped me develop a more structured sleep pattern. My doctor had given me a trial pair, so after my purchase i was able to return his loan of the glasses. He was ready to give them to another patient. I would recommend them to anyone struggling with sleep problems, as an alternative to medicine.

I actually do want to write a more detailed reply to your query. In
short, yes, I think the “blue shields” have had a positive influence on
my sleeping. And yes, I still wear them about two hours before I want
to go to bed. What might be of particular interest to you is this:
beginning in early November I switched from 2nd shift to 1st. I used
the “blue shields” to help me transition to getting up before the sun –
something I had not done in 20 months.
Sincerely,
Jay

I have been using the glasses during the week but not in the weekends. I can tell you that I noticed a difference when I sue them. I got to sleep more less a the same time every day. When i have been wearing the glasses i have been able to fall asleep easier and to have a better quality of sleep suring the night.
Thanks you.

Yes, I purchased sleep glasses and an assortment of amber bulbs to help my wife sleep better.
As I studied our overall sleep environment I also noticed light from a street lamp across the street and decided to also invest in better drapes. It took 2 sets of overlapping Wamsutta “hotel” drapes with “blackout panels” (purchased at Linens `N Things) to get it dark enough to not be able to see, for example, your own hand held at arm`s length.
Beyond question my wife is happy with your products, continuing to use them, and starting to tell others about them. Even more remarkable from my perspective is at a recent large family Thanksgiving gathering, even the younger people seemed riveted to this topic, and eager to learn more. Amazing to behold. That alone made the investment worthwhile 🙂
Date: Thu 30 Nov 10:29:57 EST 2006
Yes, I start wearing the glasses at 8 pm (unless I`m away from home). I
think they help my sleep, but since I take 3 mg. of melatonin at 10 pm it`s
hard to weed it out. My eyes do get dry when wearing them, but they`re
pretty comfortable and I can wear my reading glasses with them.
My main reason for getting them was the breast cancer link. I`ve been
diagnosed with atypical ductal hyperplasia and am going in for an
excisional biopsy soon to see if there is any associated carcinoma. My hope is that they will help me stop this disease.
I tried the lightbulbs also so I wouldn`t have to wear the glasses while reading, but the light is too soft to be used as one of the room lights. Plus, one of the lightblubs burned out already. I`ll continue to wear the glasses and use the nightlights.

Thanks for the follow-up. I do believe they are helping. I did wear them prior to the surgery @ about 2 hours prior to bedtime & @ 2 weeks.I have too many variables right now to give you a controlled answer. I had a surgery yesterday, somnoplasty, to help with the obstructive sleep apnea. I have also used a bi-pap machine & have had the uvula removal surgery. I am hopeful the combination of the 2, surgery & the glasses will help. Your premise for the production of melatonin makes perfect sense to me. I normally watch tv or work on the computer when I am awakened with an apnea. I wear the glasses after that occurrence. I seem to be able to go back to sleep faster & get into rem sleep with the glasses than before. I wear prescription glasses, so I wear your glasses over them. Yours is a wrap around design for a reason I would guess so that all blue light is blocked.
Sincerely,
Kip

yes, I purchased the glasses a month ago and have used them for2 hours prior to bed everynight. I really do think they are helping my sleep!!!. I have had a lifetime of sleep problems as well as I am a breast cancer survivor so anything I can try to get more and quality rest I will do. I am very pleased with your glasses and thank you for making them available. What a great option other than a pill! Nancy
Date: Wed 6 Dec 12:40:58 EST 2006
I use them at the computer at work. Sometimes, when I remember I use them at home when watching t.v. Yes, they are benefiting me.
Sincerely,

I have not purchased any sleepglasses; I have purchased a lightbulb and think it is great.
Date: Thu 14 Dec 16:45:15 EST 2006
I did not have any clear need for the glasses (no sleep problems or body clock issues) when I purchased the glasses. I purchased them as a proactive step to minimize blue light effects on my body clock. I have been using the glasses primarily when I use my computer or watch TV at night. I am very pleased with the purchase. I have been measuring my body temperature on days when I wear and don`t wear the glasses and so far it appears the amplitude of body temperature rhythm might be greater with use of the glasses — which based upon my knowledge of circadian body temperature I would interpret as an improvement.

Thank you for your follow up message. Yes, I have found the sleep glasses to be of benefit. I use them when I watch TV at night, and I find that I can go right sleep when I turn the TV off, rather than my previous pattern of being up and somewhat “wired” after watching TV at night. (Not that being able to watch more TV is a good thing necessarily! but it does give me a chance to unwind after a long day.)
By the way, I got to your site from psych-education.org, which I found to be a very informative site. I am not bi-polar but I have started using light therapy in the winters for seasonal affective disorder, and his site provided very helpful background references.
Best wishes for the continued growth of your product line.

Sorry for the delay in replying to your note. The glasses are a God-send. You can pry my glasses from my cold dead fingers! Occasionally I will forget to get my glasses on and I want to tell you, I am panicked! My wife continues to snore. Before the glasses I might spend one to two nights a week on the couch after being awakened in the middle of the night. The couch misses me! I continue to refer anyone who will listen to your web site. Hope your project is progressing.
Best regards,
Bernie

I have been using the sleep glasses. Although I don’t fall asleep quickly, there has only been one night since November that I have not been able to get to sleep within about thirty minutes. I will continue to use them; I feel that I am still experimenting.

I like using the combination of glasses, yellow light bulb in bedside lamp, and yellow night light. I turn them all on around 7PM every evening, and they help me wind
down so that by 9PM I can go to bed and get to sleep immediately. They are lifesavers!
Thank you,
Kira
Date: Thu 11 Jan 18:31:54 EST 2007
Yes, I am continuing to wear the glasses.
And YES! they do seem to work! I feel tired much earlier in the evening, am sleeping better, and waking earlier!
I think the concept brilliant and am very pleased with the investment.
We are also using the computer screen (nearly all of the time)… and think this is a wise safety precaution.
We are considering also lightbulbs throughout the house that have no blue light.
Thank you for your work—we have benefitted from it greatly!
Ann

Yes, I love my sleep glasses. I“ve been wearing them
since I received them and I think they are very
beneficial to my consistent sleep patterns.
Thanks,
Joel

The glasses do seem to be helping — I use them in the evening to watch TV and then keep them on until in master bedroom — I also put the amber lightbulbs in master bedroom and the nightlight in the master bath. My sleep seems more natural and deeper, with dreams but not nightmarish dreams (as with swallowing a melatonin tablet). Was previously taking a melatonin lozenge (sublingually to avoid nightmares, which are common with women who use melatonin orally) at bedtime, but now rarely have to use the supplement. Sleeping pills of ANY type just do not work for me and leave me terribly groggy the next day.
I have had low output of cortisol for several years (per saliva testing), which is purportedly the cause of my insomnia, but now feel that there is a chance for recovery from this wretched condition. THANKS
Q: Will I notice an immediate change by using these products?
A: It generally takes most people a few days before their circadian rhythms, their body’s internal clocks, can adjust. So be patient.
New Mothers FAQs
Q. Can I just install blue-blocking light bulbs in the nursery?
A. Yes, but you still need to avoid exposing your eyes to ordinary light during the night when going to the nursery, for example, in your bedroom or bathroom or hallway.
Q. Can I read while I'm feeding my baby? What kind of light should I use?
A. We recommend the lowest wattage blue blocking lamp that provides enough light for you to read comfortably.
Q. I notice you sell amber night lights. Are they a good idea for the nursery?
A. We think darkness is the best idea but using amber nightlights may be a close second choice. Using bright blue-blocking light in the nursery is fine but they should be turned off when the baby is sleeping.
Q. My older children want to have a light on at night. What do you recommend?
A. Amber night lights are our recommendation.
Cancer FAQs
Q: What evidence do we have that controlling light at night can cut the risk of cancer?
Long Answer:
Most of us are skeptics. How much evidence do we really have that using light at night is increasing the risk of cancer? Our objective here is to carefully look at that evidence. Among the most convincing pieces of evidence are the studies of the effect of long days and short nights done with animals. The hours of light and dark are abbreviated (LD), e.g. (16:8) is 16 hours of light and 8 hours of darkness. Because the reader may want to go to www.pubmed.gov to look up these abstracts, we have given the year and the author’s last name and first initials to help locate the article.

S.A.D. FAQs
Q. All I need to do is wear the glasses for a couple of hours before I go to bed?
A. Not quite. You need to avoid exposing your eyes to ordinary light on your way to bed and during the night. Using an amber night light is recommended. If putting on the glasses two hours before bedtime doesn’t work, you may try putting on the glasses even earlier. Try them for at least a week before you give up.
Q. How rapidly can one reset the circadian clock?
A. Its like jet lag. It takes a day or two for each hour change in time. If you put on the glasses two hours before your usual bedtime, it may take 4 or 5 days to advance your melatonin flow by 2 hours.
Q. I’ve been using a light box. Should I throw it away?
A. Not right away. Try the new method of wearing the glasses in the evening and see if it helps. You might want to continue to use the light box in the morning to help lock in the new schedule of earlier melatonin flow, and gradually use it less and less.
Q. If I try the glasses for a few weeks and they don’t work, can I get my money refunded?
A. Yes. We offer a 30 day money back guarantee.
Q. Will the glasses work for everyone?
A. No. Some people seem to make very little melatonin so suppressing it with light does not occur. Such people are not likely to suffer from SAD. If they do, it may be for reasons other than from having too much melatonin present in the morning.
Obesity FAQs
Q. Can I eat anything?
A:Establishing a regular schedule and improved sleep will decrease the desire to eat unhealthy foods and improve resolve to lose weight.
Q. How can I use the lowbluelight products to help me lose weight?
Q. I still need to control what I eat?
A: This is not magic. This will help you do what you know you need to do.
Q. What else should I do?
A: Put on the glasses at the same time each evening and expose your eyes to a lot of light during the day. Keeping the circadian rhythm in sync with the clock on the wall will help.
Q. Will just using the glasses make me lose weight?
A: Not if the increase in loss of fat is balanced by higher input of food.
