What should blue block glasses do for you?

Blue block glasses are designed to protect your eyes from damaging UV and HEV Blue Light (high energy visible light 380nm to ~445nm) There are 2 different types. The first are lenses that have blue light reflecting AR coatings which are clear. The second type are lenses with blue block tints. Clear lenses do not distort the colors you see. Tinted lenses filter light and can distort visible colors but can also reduce glare more effectively for light sensitive people.

Blue Block AR Coatings and Tints are rated in 2 different ways:

Blue Block AR Coatings are rated as the percentage of HEV Blue Light filtered/reflected. 

Blue Block Lens Tints are rated as the percentage of Total Blue Light filtered, not just HEV Blue light. Blue block tints are designed to not only protect your eyes from HEV Blue Light but also to address more severe types of glare issues. Blue block tinted lenses go beyond protection into what are considered "Therapy Lenses".

Blue Block AR Coatings and Tints:

BLUE BLOCK AR COATINGS

For clear, natural vision, blue block AR coatings are the way to go. Blue Block AR coatings are Anti-Reflective coatings on the surface of the lenses that reflect away damaging blue light. (They also reduce reflected glare on the lens surface making them nicer to see through and cosmetically more appealing.) The addition of light tints or special monomers in the lens material itself helps to absorb more blue light. If you are very glare sensitive, you might find that a blue block tint will be more comfortable than AR.

Mojo BluBlock AR - Good, basic protection. (50%+ HEV Blue Light)

A go-to option for people that want clear vision and that don't suffer from glare and insomnia issues. Great if you view computer screens/tablets for under 2 hours/day.

  • Polycarbonate lens material filters 100% UV.

Suggestions

If you do not suffer from glare, whether from computer screens or fluorescent lights, or TV screens, the MOJO BluBlock AR and the Apex BluBlock AR-T are a great choice especially with low to moderate computer use.

For sensitivity to glare, whether from computer screens or fluorescent lights, or TV screens, it's really your choice between the Mojo BluBlock 1.6 AR and Kodak Total Blue. Both of these coatings:

  • Protect better for heavy computer use. (Over 4 hours/day.)
  • Work better under fluorescent lighting. 
  • Work better at night with tablets and monitors.
  • In plano or distance vision prescription, work better for watching TV and driving at night.

MOJO BLUBLOCK TINTS

If you suffer from eye strain, glare, insomnia, CVS, CSR, or other blue light related issues, then a Mojo BluBlock tint is the way to go. All of our Mojo BluBlock Lens Tints not only filter 100% HEV/Blue Light, but many go beyond that with higher blue light filtration and the addition of synthetic melanin.

Our Mojo BluBlock lens tints are optimized to provide the best Blue Light protection and Beneficial Blue Light balance. This means that you get lenses that filter blue light effectively and allow beneficial blue light through to your eyes. Mojo BluBlock Tints are very comfortable to see through. Every lens is custom tinted and tested to meet or beat our published standards using a special algorithm called the Wertheim Factor. 

Blue block tinted lenses can filter/block more total blue light than Blue Block AR coated lenses. Blue block tints come in various colors and tint depths and some have other features like synthetic melanin to address insomnia issues. This can be confusing for people as there are many choices. Let's break it down to vision and glare issues, Eye strain, Glare, Insomnia. You may suffer from one of these issues or a combination. Review this info carefully. In the end it may be to your benefit to get several pairs of blue block glasses to address your particular issues.

All Blue Block Tints are a $10.00 lens option.

Eye Strain

Suffering from eye strain while using a computer or tablet may or may not be related to blue light. Addressing eye strain starts with making sure certain factors have been accounted for.

For eye strain, ask yourself:

  • Do you need reading glasses? If you do use readers, are they the right power for the distance at which you are reading?
  • Do you need prescription glasses? (Have you had an eye exam lately?)
  • Do you shift your focus away from the screen to distance frequently? (This does help with eye strain over time.)
  • Do you take medications that affect your vision?

If you are suffering from eye strain while reading a computer screen or tablet, you might need some kind of vision correction solved by getting the correct type of eyeglasses. Even a minimal prescription requiring low powers (and maybe correction for astigmatism) can go a long way to reducing eye strain.

Mild Glare

Mild issues with glare are addressed with mild tints. A light blue block tint will help with glare from computer screens as well as florescent lights.

For mild glare, ask yourself:

  • Do you suffer from mild glare issues all of the time?
  • What times of the day or night do you have these issues?

For Day Time Use We Recommend  -

  • MOJO BLUBLOCK DAY AMBER MELANIN (+44% Total Blue Light Filtration) - Cuts glare and helps to regulate circadian rhythm.
  • MOJO BLUBLOCK DAY BROWN 20 (+48% Total Blue Light Filtration) - Cuts glare while providing contrast.
  • MOJO BLUBLOCK DAY GREY 20 (+38% Total Blue Light Filtration) - Cuts glare.

For Night Time Use We Recommend -

  • MOJO BLUBLOCK NIGHT YELLOW (+42% Total Blue Light Filtration) - High contrast for night reading on tablets or monitors.
  • MOJO BLUBLOCK DAY BROWN 20 (+48% Total Blue Light Filtration) - Cuts glare while providing contrast.

Severe Glare

Severe issues with glare are addressed with more intense lens tints. These types of tints cut more glare and more blue light/HEV. They also alter the colors you see on computer screens more than lighter tints.

You are the best judge of how severe your glare issues are. We suggest that if you are unsure as to how severe your glare issues are and don't know what tint to choose, opt for the less intense tints or buy 2 or more pairs with a variety of tints.

For Severe Glare Issues We Recommend -

  • MOJO BLUBLOCK DAY TAN MELANIN (+59% Total Blue Light Filtration) - Cuts glare and helps to regulate circadian rhythm. Day time use only.
  • MOJO BLUBLOCK SUN BROWN 40 (+66% Total Blue Light Filtration) - Cuts glare while providing contrast. Day time or night time computer reading.

  • MOJO BLUBLOCK SUN BROWN 60 (+81% Total Blue Light Filtration) - This is a sunglass tint. Great for reading outdoors in sunny conditions or for driving (Plano 0.00 or distance vision prescription only.)
  • MOJO BLUBLOCK SUN GREY 60 (+63% Total Blue Light Filtration) - This is a sunglass tint. Great for reading outdoors in sunny conditions or for driving (Plano 0.00 or distance vision prescription only.)

For Very Severe Glare Issues We Recommend  -

  • MOJO BLUBLOCK THERAPY ORANGE (+74% Total Blue Light Filtration) - High contrast for night reading on tablets or monitors or during the day or at night. Will change the colors you see. Not for driving. This is the best choice for most people with very severe glare issues.
  • BPI 500/550 CR39 ORANGE-RED TINT (>125-150% Total Blue Light Filtration) - Cuts glare while providing contrast. Very intense color. Not for driving. These lenses filter all blue light and are very intense to see through. These lenses are tinted to the maximum the lenses can absorb, and will cut off anywhere from >500nm to 550nm.
  • Availability: Mojo BluBlock Tints are available in single vision and bifocals in our regular frame selection. The BPI 500/550 is only available in single vision and in full frames, (not rimless). Our Budget BluBlock Readers have a more limited selection of tints.

Insomnia

One of the ways to help with insomnia (as far as blue light is concerned) is to not view any blue light emitting screens 2 or so hours before going to bed. If you do watch TV and /or view computer screens late in the evening before retiring, here are some suggestions:

For Mild to Moderate Insomnia Issues We Recommend  -

  • Get one pair with MOJO BLUBLOCK NIGHT YELLOW tint. Use for reading tablets or monitors at night. Use with Plano 0.0 or prescription distance glasses for TV viewing.
  • Get a second pair with MOJO BLUBLOCK DAY AMBER MELANIN tint. Use during the day.
  • A good third pair would be with the APEX BluBlock AR-T coating for clear vision when you want it during the day or night. Availability: Single vision only, in all full frame styles. (not rimless)

For More Severe Insomnia Issues We Recommend  -

  • Get one pair with MOJO BLUBLOCK THERAPY ORANGE tint. Use for reading tablets or monitors at night. Use with Plano 0.0 or prescription distance glasses for TV viewing.
  • Get a second pair with MOJO BLUBLOCK DAY TAN MELANIN tint. Use during the day.
  • A good third pair would be with the MOJO BLUBLOCK 1.6AR or KODAK TOTAL BLUE 1.6AR coating for clear vision when you want it during the day or night.

Suggestions

To address your personal glare, blue light/HEV, and CVS issues, consider getting several pairs with different options.  

If you are unsure of which tint to choose based on severity, opt for the lesser intense options. Allowing more blue light through to your eyes is better than going with something that filters more blue light than necessary.

Get an eye exam. If you need prescription glasses for reading, distance, or computer distance, buy them.

Understand that some vision issues can be related to things like medication, pregnancy, and a myriad of other conditions. Please consult with your doctor about what vision issue you are experiencing.

 

OTHER ISSUES - There are a myriad of other issues related to glare. Extreme photophobia, Central Serous Retinopathy (CSR), color blindness, and more that can be treated with certain lens tints. The first thing to do is to talk to your eye doctor and get some guidance. We do not provide advice on these health conditions. A great source online for severe glare issues is Glarminy.com. The comment sections are filled with people's experiences with certain issues as well as with products they have tried.

  • Mojo BluBlock Tints are designed to filter the maximum amount of blue light/HEV for that tint color while allowing beneficial blue light through to your eyes. We use the Wertheim Factor to rate and optimize our blue block tints. (Learn about the Wertheim Factor and how the effectiveness of blue block lenses is determined.)
  • For severe glare issues, try Mojo BluBlock Day Tan, Mojo BluBlock Therapy Orange, or BPI 500/550 which filters to 500-550nm.
  • Our Mojo BluBlock Sun lenses are designed to use outdoors. They are not designed for indoor computer reading.
  • Therapy Orange and BPI 500/550 are not to be worn for driving as they can null out traffic lights. (Plano and distance prescription)

Blue Block with Zero Power or Prescription Lenses

All of our blue block options are available in zero power or prescription lenses for distance vision, computer distance, or up-close reading. Here are a few tips:

Zero Power Lenses - If you do not need reading power or prescription lenses but would still like to protect your eyes from blue light and the effects of CVS, then your best choice is one of our AR coatings. These allow you to see your TV or monitor naturally without adding a color in front of your eyes. If you are light sensitive then opt for a Mojo BluBlock Tint. Simply select zero for each lens power and select the add-on that you want.

Prescription Lenses - For distance vision we recommend the AR coatings unless you want sunglasses, but the choice is yours. For prescription lenses go here.

  1. Find your frame.
