Blue Light is Causing Problems.
Our MojoBluBlock Lenses Can Solve Them.
If you are one of the millions of people that use an iPad, tablet, or e-reader, you may be having some problems. Recent studies have been showing that intensive use of these devices, are causing headaches, eye strain, dizziness, and insomnia.
Why? Well it has to do with a specific part of the blue light spectrum that are emitted by these devices. There is a misconception that all blue light is bad and that is simply not true. It is not all blue light. In the visible light spectrum, blue light is a good thing (495-465nm) so you would not want to filter out all blue light.
The blue light that is causing problems is part of the Near Ultra-Violet-A spectrum. Based on current research, the most harmful part of the near UV-A blue light spectrum, a 40nm band at 455nm-415nm. This range was determined from research done by the Paris Vision Institute in 2008. This 40nm band causes the most retinal damage.
We have known for a long time that UV-A and UV-B light to 400nm can be physically harmful. Now there is data that suggests that "Near UV-A" at between 455-415nm can cause problems running from headaches and insomnia to possibly damaging your eyes.
The high energy and severe scattering of this band of blue light is a cause of glare and flash. Blue light emitted by electronics such as computer monitors, televisions, smartphones, as well as LED light sources during the day or night will easily cause eye strain and fatigue.
There have been many scientific studies done on the effects of blue light from electronic devices on human eyes. See current resources at the bottom of this page.
We Have Solutions:
"Traditional blue blockers give you pretty sunsets, but that's not what you want. You don't want color distortion; you want your colors to be natural. The traditional blue blockers do not discriminate in the blue light spectrum. They just block all the blue light." - Dr. Ronald Melton, OD from: The Lowdown on Blue Light: Good vs. Bad, and Its Connection to AMD The Review of Optometry.
If you are having blue light problems, we now offer 2 solutions, Mojo BluBlock Tints and Mojo BluBlock AR anti-reflective coating. You can get these tints or coatings with or without a reading power. (No reading power needed? Select "Plano 0.00" for each eye.)
1. Mojo BluBlock Tints. (Available in 3 Colors) We have developed our blue light filtering tints to filter out Near UV-A, UV-A, and UV-B, to 550nm and with our great collection of frames you have the perfect pair of Monitor Reading Glasses. Like most of our readers, you can select from no power to +4.00 in either eye. The lenses are aspheric polycarbonate with scratch resistance.
- Amber- Best color for nighttime reading. Good for iPads, Tablets, and computer screens. Best color for increasing contrast.
- Brown- For nighttime or daytime reading. Good for any computer use. Cuts glare and is good for increasing contrast.
- Gray- Daytime reading. Cuts glare well. Does not offer better contrast but the colors you see are natural.
Tint Depths: 15% or 30% for indoor use, 45% or 60% for outdoor use.
2. Mojo BluBlock AR Coating- An alternative to having a tint. Mojo BluBlock AR is our new premium anti-reflective coating that reflects away, as opposed to filtering out unwanted blue light (Near UV-A) from computer screens, iPads and tablets. There is no tint in the lenses. They are super clear polycarbonate and include scratch resistance and a hydrophobic coating that makes them easy to clean. (Please note that we cannot combine AR coatings and tint.)
- Reflected Blue light to 470nm. Provides optimum comfort with clearer vision and increased contrast sensitivity.
- 40% increase of light transmission to your eyes. (Good light, not bad light)
- Powerful Nano-organic scratch resistance, and Plasma-Ion anti-static properties which prevents dust accumulation.
- Easy-Clean surface makes it easier to clean and continues to maintain clean lenses.
- Toughest Impact- Best in class with 170% increase in impact resistance. (Great for wearers exposed to hazardous environments.)
MojoBluBlock Tints vs. Mojo BluBlock AR - Both options protect your eyes from blue light. The tints filter light to 550nm while the AR reflects off blue light to 470nm letting beneficial blue light through. The amber tint is particularly good for night reading as the color increases contrast. The other tints work well to dampen glare. Mojo BluBlock AR has no tint and is very clear. It reduces reflections and is a great alternative for folks that don't like having a visible tint in their lenses.
Choosing the right power-
Monitor (tablet) Reading Glasses- Most people read their tablets or iPads at 12-14 inches away. Choose your up-close reading power.
Computer Reading Glasses- A typical computer user views the screen at about arm's length. Choose half of your up-close reading power. Ex: +1.50 for up close reading, choose +0.75 for computer use.
No Reading Power- Select Plano 0.00 for each eye.

Recent Questions and Concerns.
Common Misconceptions. Please read my recent blog post- common-misconceptions-about-blue-light-and-blue-block-lenses/
Can Blue Light Actually Damage My Eyes? According to several studies, there is a strong possiblity that intensive, blue light (Near UV-A) exposure, can possibly cause retinal damage and senile macular degeneration. Some people are more at-risk than others, especially the young.
Not all blue light is bad. Blue light, the non-offensive type, is important for good vision.
The studies that have been conducted so far are indicating that a small part of the UV spectrum, Near UV-A at 420 to 381nm is not only causing problems like eye strain and insomnia, but also causing more serious eye-health problems. It has been known for a long time that UV-A and UV-B (400 to 280nm) light are damaging to the eyes. (It also damages your skin) UV-400 filters have been available (or inherent in certain lens materials) in eyeglass lenses for the last 40 years or so. It is not particularly surprising that this part of the Near UV-A spectrum is also an issue especially with long exposure to Near UV-A from electronic devices.
While some people don't experience problems like insomnia or eye strain, it doesn't mean that their eyes are not at risk.
How do Blue Light Issues relate to Computer Vision Syndrome? Computer Vision Syndrome (CVS) is a grouping of visual problems related to issues like glare, and extended focussing on one set point, a computer screen. The glare issues can be resolved with Anti-reflective computer screens or covers, or eyeglass lenses with anti-reflective coatings. The other issue is related to your eyes' ability to "accomodate" at different viewing distances. (If you stare at a pencil at 20 inches in front of your eyes for 8 hours a day, I can guarantee that you will eventually have problems shifting focus to nearer and farther points.) The solution to CVS is Computer Reading Glasses with an AR Coating or Computer Bifocals with AR Coating, for people that require a computer distance reading power and a near distance power.
I think that "Blue Light" issues will eventually be included as a part of the syndrome, in "Computer Vision Sydrome".
I experience these Blue-Light problems, especially when reading at night. This is a CVS and blue light issue.
Tips: Ambient light and reading properly- If you want to keep your eyes in optimal health, do these 3 things:
1. Reading at night- Have a background light source and have a light source directed to your reading material. The more light on what you are reading, the better.
2. Whether reading at night or during the day it is very important to shift your focus from near to far every five minutes or so. If you focus your eyes at a near point for long periods, your eyes will eventually lose the ability to accommodate to different distances, and you will need reading glasses sooner.
3. Get glasses with our Mojo BluBlock Tint or Mojo BluBlock AR. Available with or without magnification and in single vision prescription powers.
What About E-Ink Screens? I was an early adopter of the Kindle and I have to say, it did what it did very well. I love matte screens but hate the very low (no) value internet experience. In daylight, the Kindle was readable indoors and outside with no eye strain and absolutely no glare outside. It was very light weight and comfortable to hold. The problem was that in order to read at night, I had to put it in a cover and attach a book light which trippled the weight, making it uncomfortable to hold for long periods.
Here's the thing- as far as CVS and blue light, and their related vision issues, there is no evidence that E-Ink screens are any better than LED screens.
Amber Colored Lenses Amber is a color. While amber tinted lenses can help with improving contrast, amber tinted lenses do not necessarily filter Near UV-A. We use specially designed tints in amber, brown, and grey, to filter Near UV-A (and UV-A and B). Each color serves different purposes. We also offer non tinted, blue blocking anti-reflective lenses which reflect Near UV-A away from your eyes and filter UV-A and B.
Latest Customer Reviews for Mojo BluBlock-
"The most recent pair I got from you guys I added the Mojo Blue Blocker AR coating - what a difference - having had cataract surgery with multifocal lenses I can read fine and see distance. But when I work on my large computer screen at home it's about 2.5 - 3 feet away which is my dead spot. The first pair (once I got the power straight) caused some fatigue and strain, but when I got the last pair with the coating, wow! I can sit all day in front of the screen without any problems. Great glasses. Thanks!!" -Alan B.
"I have been using drugstore readers now for about 3 years. I am one who never had to wear glasses and never wanted to. However age has other plans. Since I love to read I had to give in. I found that after a month or so, my readers would start to fog or just not work as well. I was having a lot of eyestrain from forcing my reading by squinting or moving my book back and forth until I had no choice but to buy yet another pair."
"After a couple of years, I started having a harder and harder time reading on the computer. (Standard desktop). I,unfortunately, started slipping on my readers thinking this would help. Bad, Bad, decision! I soon could not read the computer without the readers. Then, my eyestrain, headaches, dizziness, exploded. I tried going to two diffferent eye doctors. Each told me different things, patted me on the head, and sent me on my way. Needless to say, I was very very frustrated."
"I began an online search to help myself discover a solution. I soon learned that normal reading uses one's near vision and computer reading
uses one's intermediate vision. By using my readers for both, I was confusing my eye muscles. The strain this put on my eyes was what was contributing so much to my problems. I also learned that drugstore readers DO NOT use optician quality lenses. This is why they do not last and are ultimately harmful to your eyes."
"I then discovered readingglassesetc.com. Through several very informative email exchanges, I learned that they had several quality options for me. I tried bifocal readers, mojo bluebock monitor readers and AR readers the latter two both with computer intermediate vision. This I was informed is 1/2 of your near reading magnification. For me this is a +1.25. All three had high quality frames and lenses. My final personal choice was the AR (anti reflective) readers. Just trying these for 2 days allowed me to discern a drastic difference in clarity and brightness. I have had them for about a week now, and I no longer am having any headaches!!"
"The mojo blublock monitor readers are also excellent. I do not use a smart phone, or a tablet, or a laptop, but both my husband and son in law do. We all three noticed an amazing difference when viewing each of these items through the mojo lenses. They have done an excellent job in creating a lens coating that decreases the blue light from back lit items without interfering with one's ability to clearly see print, pictures, and movies for extended periods of time. I believe these are a must for anyone who uses handheld back lit devices. We all only have one set of eyes, and in today's world, taking care of them has never been more important."
"The folks at Reading Glasses Etc have done an amazing job with keeping up with technology and offering quality well made eyewear solutions for a wide variety of needs at a very reasonable price.I believe they hold themselves to a high standard and provide excellent personal customer service. You will not regret making your purchase with them."
"I truly appreciate the help and advice. I am enjoying my computer readers and can't wait to get my regular readers."
"Mojo BluBlock Tint: These are amazing in my opinion.
The 15% Blue Block tint depth gives you just enough tint to block that blue haze that is all around us during sunny bright day, or if you sitting in a front of a laptop, or holding a tablet. I did not notice that blue haze that outdoor offers until I wore the these glasses for a while. Not only do they block the haze but they make everything sharper, and colors are little stronger and they pop. They don't do much difference indoors as far as looking around, but they help with looking at laptop or watching tv, or reading e-book on my cellphone.
The 30% Blue Block tint works just as well as 15% but little darker. It does change some of the colors I see."
