Mojo BluBlock Tints - Balanced blue light protection.

For the vast majority of people, clear blue block lenses are the preferred option. Wearing tinted lenses indoors has it's downside as your eyes can become more light sensitive over time. We suggest that you consider a Blue Block AR option first. These lenses provide UV protection and varying degrees of HEV Blue Light protection. Learn more about Blue Block AR Coatings. For people that need lenses that reduce glare to a more significant degree, we offer a unique line of lens tints that reduce glare and allow beneficial blue light through to your eyes. Beneficial blue light (from 455nm to 500nm) provides clearer vision and helps regulate circadian rhythm.

Mojo BluBlock Tints

  • The perfect balance between protection and visual acuity.
  • Better looking. Full UV/HEV Blue Light protection with lighter, less obnoxiously tinted lenses.
  • Easier on the eyes. Balanced blue block tints provide much more natural and comfortable vision.

Mojo Blue Block Night, Mojo BluBlock Day, Mojo BluBlock Sun

For those people that want or need additional help with computer glare, bright or fluorescent or LED lights, or are photophobic to any degree, our new Mojo BluBlock Tint formulations are designed to offer optimal blue light protection while allowing beneficial light through to your eyes. All of our Mojo BluBlock Tints filter a high level of HEV Blue Light. We are now using a new valuation in our tint descriptions called the Wertheim Factor which better defines the quality of blue block lenses. Our BluBlock Lens Tints filter varying degrees (percentages) of blue light depending on the color and color depth.  

See our Mojo BluBlock Tints below. If you would like to learn more about our Mojo BluBlock Tints, you can see - Spectrograms and Light Transmission Details  Also see our Blue Block Guide on how to choose the best blue block option for you.

[TIP: To address common insomnia issues, consider a combination. As a general rule it is better to use a clear blue block option during the day. Consider a blue block AR coating for daytime use and a tinted pair in the evening or at night.]

bpi500-550.pngBPI 500 and 550 CR39 Orange-Red, Red-Orange Tints

It is very rare that the average person would need this degree of tint. We recommend that you consult your Eye Doctor about whether lens tints like this are right for you.

These tints are not Mojo BluBlock tints and do not allow any beneficial blue light through to your eyes. These are made by Brain Power Inc. (BPI) and filter blue light to cut-offs 500nm up to 550nm. It is for those who for whatever reason, need total blue light filtration. These tints will alter the colors you see. Please Note: These lenses are CR39 resin, not polycarbonate and are not for children under 18. They are not for driving as they will blank out traffic lights. Also, in high powers they will be much thicker and heavier.

BPI 500 Color: Orange-Red  Depth: ~80%  Feel: Very intense. Use: Indoors or outdoors for reading. Filters 100% of blue light to 500nm.

BPI 550 Color: Red-Orange  Depth: ~90%  Feel: Very intense. Use: Indoors or outdoors for reading. Filters over 100% of blue light to 550nm.

These lens tints are available as a lens option in all of our full frames (not rimless) as single vision for reading as well as bifocal reading glasses. These tints are also available in prescription for single vision reading, computer, or distance vision.

  • A new lens option, Mojo Photo Grey AR lenses are polycarbonate lenses that lighten and darken from a light 1% indoor tint to about 70% outdoors.
  • These lenses filter all UV light and some blue light.
  • The AR coating includes an additional hydrophobic coating that makes them easy to keep clean.

 

 

trans7polysv.jpgTransitions Signature 7 Lenses

The new Transitions Signature VII lenses have a built in blue light filter called Smart Blue Filter (SBF). SBF filters about 20% of harmful blue light indoors and up to 85% outdoors! They are clear indoors and darken quickly to full sunglass depth within about 45 seconds! These are polycarbonate lenses with 100% UV protection available in:

  • Grey - Very neutral for general use.
  • Brown - For higher contrast
  • Green - A balance between neutral and contrast. 

The WERTHEIM FACTOR

Balance. We view our blue block offerings as a vision health aid. We are now using various tint colors in specific tint depths to provide a optimal blue light/beneficial light balance. This balance is calculated as a value called the Wertheim Factor. (Patent Pending - see the Patent Application here.)

From the Patent- "The Wertheim Factor is a calculation utilizing a computer algorithm to analyze the transmission spectrum of an ophthalmic lens or filter. It then takes a ratio of the total energy blocked by the filter in the spectral region under study to the total optical energy available in the spectral region under study. This ratio is then multiplied by the luminous transmittance of the filter. The algorithm then outputs this figure of merit, the Wertheim Factor, expressed as a percentage. The actual value will change depending on the wavelength range chosen so that when comparing lenses, they must all be evaluated over the same spectral range. In order to be meaningful, the spectral range must include the photopic region, centered on 550 nm, as well as the region of the spectrum considered to be harmful. In the preferred embodiment, the spectral range used is from 315 nm to 780 nm."

Simply put, we can read the transmission of light through a lens with a special UV/Blue Light spectrometer and see what types of light are being transmitted and what are being filtered. Black, or air has a Wertheim Factor of 00. A perfectly balanced lens filtering blue light/HEV and allowing beneficial light through, would have a Wertheim Factor of about 43 and is pretty rare.

Wertheim Factor Lens Tint Type Blue/HEV and Beneficial Light Balance
0.00 No lens or black Black or Air N/A
10 to 20 Typical Non-blue block tint Poor at filtering blue/HEV
21 to 29 Brown or Grey blue block tints Good at filtering blue/HEV and glare outdoors
30 to 43 Medium to bright blue block tints Very Good to Excellent at filtering blue/HEV and provide the best vision.
Over 43 Highly saturated tints Therapy lens tints (see below*)

 

Darker brown or grey blue block tints can result in more HEV/blue light being filtered, but also means that more beneficial light gets filtered out too, which will result in a lower Wertheim Factor. This is fine for sunglasses.

*Highly saturated yellow or orange lenses will result in a higher Wertheim Factor but will filter more blue/HEV than necessary and result in a very intense visual feel and look cosmetically unappealing. These tints can have benefits as "Therapy Tints".

Therapy Tints - For the vast majority of people there is no reason to block out beneficial light, blue or not. If you spend a lot of time sitting in front of a computer screen or using a tablet or cell phone, any of our blue block solutions, whether reading glasses or prescription will protect your eyes more than adequately. Therapy tints are typically a very intense yellow, orange, or red and are sometimes used by Eye Doctors to address various vision or health issues like color blindness, autism, retinitus pigmentosa, and many others. If for some reason you believe that blocking out all blue light/HEV or any beneficial light is something you need, then please consult with your eye doctor for advice. We can provide a number of different therapy tints by special request.

The value of using the Wertheim Factor:

  1. It establishes a better standard of quality for blue block tinted lenses.
  2. Using a special UV/BLUE LIGHT spectrometer we can measure this value for all of our blue block tinted lenses and we can maintain and even improve quality over time.
  3. It provides a simple way to understand the overall quality of blue block tinted products for consumers.

ReadingGlassesETC is one of the first companies to offer these innovative new vision health products using the Wertheim Factor as a quality standard. We have created Mojo BluBlock tints to provide optimal vision protection, the best optics, and the best value for computer users everywhere. Try them. You will love them. Send us feedback!
