User questions & answers

Question:	How much do these change your color vision
Answer:	Yes, but not a stable platform for playing CD on the move, (skips, and pauses).
Question:	Does anyone wear this in front of the computer at work for 8 hours? Does it make u sleepy
Answer:	I don't have this exact cd player, but one like it. With mine, if you press the play button while playing, it pauses and if you press it again it starts to play where you left off. Hope this helps.
Question:	Are these clip ons lightweight
Answer:	no.it is not shock/skip free
Question:	Can I wear these during the daytime? They look really cool and classy
Answer:	It will record until the battery dies. Not part of your question; the sound is very "tinny".

• BRIGHT & CLEAR LENSES - These are designed to pass as much non-blue light through as possible. There is no dark tint and they are not polarized. You can still make eye contact with loved ones and even forget you are wearing them.
• SPORTS FRAMES - The durable TR90 thermoplastic frames are lightweight and flexible.
• WRAPAROUND FIT - The wraparound keeps light from getting around the lenses. Lens-bridge-temple: 61-16-127
• TECHNICAL SPECS - Tested to block 100% of light from 280 - 490nm (this includes UV). Blocks 99.82% of light in the critical 450 - 510nm range. This is the most disruptive wavelength of light at night. It is also the same frequency of light that is blasted directly into your eyeballs from electronic devices! Always wear protection!

User questions & answers

Question:	When I read on the computer at night with these glasses, it is causing eye strain. Any suggestions
Answer:	Hi Sandy, Well that's unfortunate and not typical. If you read some of the reviews you'll find that many people wear them to relieves eye strain!I would experiment with changing the contrast and brightness levels on you screen. Low contrast can definitely cause eye strain. Also on some websites that use different background colors or text, the color shift may make it harder to read. Some browsers have readability plugins that will reformat a webpage to make it easier to read. I hope that helps.
Question:	Can these be worn forvdriving at night
Answer:	No, these are not right for night driving, they block too much light. Do a search for ‘night driving glasses’ to find something more appropriate.
Question:	Where can I buy better quality glasses? Is the price cheap
Answer:	I found a website for branded sunglasses, cheap and good quality! , I have bought 63, the quality is good, and the logistics is very fast!
Question:	Do these glasses really help you to sleep better? I already have my iPad with night light on so the light is more yellow
Answer:	I agree that Amanda is wrong here. The night features on Apple products only reduces blue light somewhat, and even with full night mode on, if I spend a little time on my iPhone right before bed without glasses, it kills my drowsiness and I have a harder time getting to sleep. With these on I still feel myself getting tired as I use the phone and fall right to sleep.

Blue light after dark squashes your natural melatonin production

Blue light exposure at night has been proven time and time again to be disastrous to your body’s internal clockwork. Your brain tracks the time of day with special receptors in the eye that sense lighting conditions. They are specially tuned to be sensitive to blue light. This is a problem because blue light exposure after dark sends daytime signals to your brain. This can scramble you natural circadian rhythm. Not Good…

The Disruption Zone

While the body is sensitive to higher levels of all visible light, the range of 450 - 510nm is by FAR the most disruptive. This is longer blue and cyan wavelengths that clear and yellow tint lenses are helpless to block.

Sports Frames

The wraparound fit keeps out nasty blue light from creeping around the sides and top of the lenses.

Comfortable

Because the frames are flexible they fit a wide range of head sizes and shapes. They are so comfortable that you might even forget that you have them on!

The Secret “Sleep Hack” of High Performers

It's amazing how many top level entrepreneurs and athletes use blue blocking glasses at night. Up until recently, it has been a closely guarded performance secret.

There is more than one major league team using blue blocking glasses at night. It's not surprising really. Great sleep = great recovery!

Allow fast sleep onset

By preventing blue light from decimating your melatonin levels, you are giving yourself an opportunity for a great night of sleep.

You need darkness at night! Treat yourself. Block the blue in the evening and allow your sleep onset to come naturally.

Natural Rhythms of light and darkness

Stable patterns of light and darkness provide a solid foundation for health and wellness. This is a major component of a healthy lifestyle that is only recently becoming recognized.

We all know how great a good night of sleep feels!

User questions & answers

Question:	Can these be returned if they do not fit
Answer:	Buying from AMAZON you can always return.
Question:	Can I wear these at work over 10 hours
Answer:	Hi Lily, Thank you for your question. The purpose-made lenses in these Blue Light Blocking Glasses have been developed to give the best Sleep Optimization effect, blocking out blue light from reaching Specialized Photoreceptors in the eyes. These photoreceptors work both ways like an on and off switch, where the presence of Blue Light tells your body that its daytime. For this reason, it's recommended to have a lower filtration level letting in more blue light during Daytime Work sessions. Due to customer requests, we have developed a new type of CR39 Lens suitable Professional Daytime use. This lens is balanced to Protect the Eyes from the harshest HEV (High Energy Visible) Light emitted by digital displays and at the same time let through enough light for the bodies Circadian Rhythm Regulation. Models with this lens will be available for purchase at the beginning of next year, using the same Quality materials as the existing range. Feel free to contact us for any other requests or questions. Sincerely, THL Sleep Support
Question:	What percentage of Blue light do these glasses block
Answer:	Hi SCS, Thanks you for your question. The custom made CR39 lenses blocks out 99,5% of the blue light spectrum, which includes the interval 460-480 nm that have been proven to have the most Melatonin Suppressing effect. Feel free to contact us if you have any further questions.
Question:	Why do some of these blue blocker glasses have clear lenses, and some have orange lenses
Answer:	Hi Duane, Thank you for your question. The lens color range available on the market from clear all the way to deep red, is roughly proportional to the amount of blue light they will block out. The custom made dark amber lenses in our glasses blocks out 99,5% of the blue light spectrum and are balanced to let in maximal amounts of safe light to give a relaxed viewing experience. When developing this lens, we tested various lens color options where clear lenses managed to block out maximum 35% and yellow about 70% of the blue light spectrum. These characteristics are not sufficient for sleep optimization, as they will fail to block out light between 460-480 nm that have been proven to have the most Melatonin Suppressing effect. Feel free to contact us if you have any further questions.

User questions & answers

Question:	Can these be worn during the day if I watch television and work on the computer as well
Answer:	Hello, Typically, fully blue blocking is not necessary during the daytime. That being said, we do have customers who wear them during the day. They often do so because of health problems like macular degeneration, light induced migraines, or just an extra sensitivity to blue light. Blue light is a powerful "daytime" signal to the brain. This is terrible at night but desirable during the day. We recommend taking them off to get some full spectrum light if you are wearing them for long periods of time during the day.
Question:	Are these returnable if they do not fit
Answer:	Yes I did no problem Amazon is great
Question:	Do these have a bad glare or do they have an anti reflective coating
Answer:	Hi, They do have a basic anti-reflective coating. Of course it is not a brand name coating like you would pay extra for at the eye doctor, but it works.
Question:	Where are these made
Answer:	China (for now). We are currently looking for new supply chain options.

Easily put them on and take them off

They just set over top of your regular glasses. There are no clips to deal with. This is very convenient if you use multiple glasses or if you use them with glasses only some of the time.

Don't let blue light ruin your sleep!

By now we all know that screens emit a high percentage of blue light which is bad for sleep. Now when you need to use your tablet or other screens before bed, just put these on first. Problem solved!

Instant relief for your eyes

User questions & answers

Question:	Do the orange lenses work for night driving (or just the yellow
Answer:	The yellow lenses are specifically used for night driving. The orange lenses are not safe for driving because they might change the color perception. Thanks.
Question:	Are the lenses plastic? I have another brand that has platic lenses and they dont work very well
Answer:	These lenses are made of triacetate cellulose (TAC), which gives high clarity, contrast and polarization. They are not the cheap plastic.
Question:	Do they fit without without other glasses, can they be worn alone, will I be looking silly wearing these by themselves
Answer:	I have found that these are bigger to fit over regular glasses. So when worn without, they don’t sit right on me. They slide lower on my nose.

Product description

How they work: Wearing Sundown Eyewear with PaleoTech red lenses in the evening reduces the negative effects of artificial light exposure. It does this by mimicking natural light exposure that, as the evening darkens, signals our brain to prepare for rest. Why they work: Circadian rhythms (daily hormone changes related to light) govern much of our most basic biology. Re-synchronizing our hormone system results in not just a better sleep, but better brain function, better athletic performance and better metabolic function. The second way these eyewear function is by significantly reducing the light received by your eyes prior to bed. Our lenses block 92% of all the incoming light to function as ‘Dark Therapy’ eyewear that enhances melatonin response and sleep. Avoiding screens and artificial lights is the best practice but if artificial lights and screens are unavoidable, these eyewear are the next best thing. Sundown Eyewear block 99.8% of blue and green light under 580nm. That's all the wavelengths of brain exciting, sleep disturbing light. Blue, green and bright light suppress the onset of the sleep hormone melatonin resulting in difficulty falling and staying asleep. Screens can be difficult to read as a result of blocking blue and green light. Use ’greyscale' (black and white) screen setting for best function but avoid screens when possible since they're not conducive to sleep. You may see some faint purple or violet, this is normal. Refer to our transmission values (<435 or >750nm) Our eyewear is designed to fit large faces with the foam removed (5' wide at temple) and small faces with the foam attached (4.5" wide at temple). These are not designed to fit over glasses. Best results are realized when used at least 30 min (or more) prior to bed and after 7 to 10 nights of continuous use and in conjunction with a comprehensive sleep strategy that aims to strengthen circadian rhythm.

• Block 99.9% of the full spectrum of blue and green light (400nm to 580nm) for better sleep. WHY RED? Studies show that green light disrupts sleep just like blue light and our PaleoTech red lens blocks both. Orange lenses don’t block green light.
• DARK THERAPY: Is the process of greatly reducing exposure to any light during the hours before sleep. This is done to prevent the breakdown of melatonin by blue (and green) light, which is an important hormone involved in regulating the bodily circadian rhythm. Our eyewear offers a novel approach to dark therapy for sleep because they are designed to block 92% of total light as well as 99.9% blue and green light. Darkness improves sleep.
• IMPROVED CIRCADIAN RHYTHM: This is the goal. It has been shown to benefit nearly all aspects of health and recovery. Better sleep is just one important result of improved circadian rhythm. The darkness created by our eyewear is an important component to strengthen this rhythm but it must be accompanied with increased daytime light exposure (bare eyes)to be most effective. For best results a comprehensive strategy should be implemented (refer to diagram).
• FEEL BETTER NATURALLY - Conditions that show improvement from circadian rhythm regulation include: Sleep Disorders, Weight Management, Sports Performance and Muscular Recovery, Lyme Disease, Infertility, Jet Lag, Anxiety, Diabetes, Postpartum Depression, Seasonal Affective Disorder, Bipolar Disorder, ADHD, Neurodegenerative Disease, Heart Disease, Cancer and other Metabolic Related Diseases and Conditions.
• Notes: 1. This model is not designed to fit over glasses. 2. These dark lenses are designed to mimic darkness - it’s one of the reasons they are so effective. Therefore, they are quite dark and are best used while relaxing before bed while doing pre-sleep activities like reading. 3. The red colour of the lens may take 10 minutes or more to get used to. 4. Effects are best realized after 7 or more nights of continuous use. 5. 1 or 2 nights is an insufficient test of the products effectiveness.

User questions & answers

Question:	I want to try these out. Can they be returned if they are ineffective for insomnia
Answer:	I found them highly effective for sleep disorders. Wear for an hour or two before bed. I used to wear them while sleeping but now find that unnecessary.
Question:	Does this really block most of not all of the green and red lights when worn? I’m looking to block these lights to help with sleep
Answer:	Hello. Yes this is exactly the purpose of these eyewear. They block 99.9% of the full spectrum of blue and green light. They are also dark to strengthen the hormone response. We've seen the best results using these while reading for 20 min before bed.
Question:	are the paleo-tech sundown sleep wear with padded foam frames available in a prescription lens if I upload the prescription
Answer:	Not that I am aware of. You would need to go to an online prescription eyeglass site.
Question:	Can you specify the transmission of the glasses? Especially green light wavelength
Answer:	The listing states that the lens eliminates 99.8% light below 580nm. 580nm is the end of the green spectrum and beginning of yellow. This is where the transmission values start to raise slowly and then increase significantly above 680nm which is well inside the red spectrum. Here are the actual transmission values of the PaleoTech Lens: 280nm: 0.00%, 290nm: 0.00%, 300nm: 0.00%, 310nm: 0.00%, 320nm: 0.00%, 330nm: 0.00%, 340nm: 0.00%, 350nm: 0.00%, 360nm: 0.00%, 370nm: 0.00%, 370nm: 0.00%, 380nm: 0.00%, 390nm: 0.00%, 400nm: 0.00%, 410nm: 1.316%, 420nm: 3.145%, 430nm: 1.040%, 440nm: 0.322%, 450nm: 0.041%, 460nm: 0.00%, 470nm: 0.00%, 480: 0.00%, 490nm: 0.00%, 500nm: 0.00%, 510nm: 0.00%, 520nm: 0.00%, 530nm: 0.00%, 540nm: 0.00%, 550nm: 0.00%, 560nm: 0.00%, 570nm: 0.121%, 580nm: 1.484%, 590nm: 7.914%, 600nm: 22.021%, 610nm: 38.785%, 620nm: 51.668%, 630nm: 58.877%, 640nm: 62.170%, 650nm: 63.762%, 660nm: 65.087%, 670nm: 66.428%, 680nm: 67.799%, 690nm: 68.545%, 700nm: 68.816%, 710: 68.563%, 720: 68.217%, 730nm: 68.036%, 740nm: 68.359%, 750nm: 69.201%, 760nm: 70.081%, 770nm: 70.531%, 780nm: 71.051%.
