Step #1: Test your blue light sensitivity

Here’s a scientific fact:

Today, there is no way around testing blue blockers!
If you want them to work. For you!

You have to wear them. For a while!

You have to try different tints – blue cuts, blue blocking levels.

Only then can you:
– rule out the ones that don’t work or cause negative side effects, and
– know which anti blue light glasses work best.

Others (sellers, reviewers, doctors, scientists, experts, users, celebrities …) can tell you which blue blockers work:
– for them, or
– for many people, or
– maybe even for most people.

Now:

That doesn’t guarantee the same blue light glasses will also work for you!

Why?

– Because your sensitivity to blue light is different.

– And likely also your lifestyle. And lighting conditions.

– And your problem with blue light.

[More on this below].

Bottom line:

Your blue light sensitivity is unique. So:

Taking advice on blue blocker glasses from others without testing is risky.

 

NOTE:
Would you let others tell you what prescription is ideal for you?
No-one would accept that.
Only you can know how well you see with this or that lens power.

It’s the same with blue blockers. There is no substitute for testing!

 

Testing alternatives:

There are three ways to test your eyes for ideal blue blockers:

1 – Test by ordering and returning. Eventually, you might find glasses that really work for you.

But, if you are not lucky:
– the first order (or a few of them) may not match your blue light sensitivity, and
– you may decide blue blockers don’t work…
…and miss out on the opportunity to fix your problem.

2 – Borrow blue blockers at a local low vision agency. You should also get qualified and personalized advice there. Consider it!

3 – Use the Blue blocker Test kit [Disclosure: We make & sell it].

Now:

We designed the Blue blocker Test kit to be the simplest and the most effective option:

It works for all blue-light-related problems, and

– You can use it as glasses or over-glasses.

Bluelight filter test kit

The Blue blocker glasses Test kit

The Tester includes a card-stock frame and 8 different blue light Filters.

We chose the filters to tell you the most about:

– your blue light sensitivity, and
– any possible negative side-effects of different blue blockers available for sale.

Testing procedure: Try one Filter after another…

… easy, right?

But, if you want to be methodical: Follow these instructions.

TIP 1: Test while doing things you usually do. Particularly those that could be causing your problem.
TIP 2: Don't jump to conclusions too quickly (to avoid the placebo effect).

 

Outcomes

When you finish testing you’ll either:

– Rule out Blue light as a cause of your problem. So, you can focus on other possible causes.

Or:

– Find that one of the kit Filters (let’s call it #X) works best for you. So, it’s time for Step 2.

Step #2: Identify matching blue light glasses. With one click! 🙂

It is as easy as clicking only once. (We’ve done all the hard work for you).

Further down, there is a list of all 8 kit Filters (from #0 to #7)

You will click on your favorite Filter number.

It will take you to Group #X. It’s a review of blue light glasses that will work for you like Filter #X.

Why?

Because they all match your blue light sensitivity. Like the Filter #X.

 

NOTE:
Blue blockers in Group #X
filter blue light like
your favorite Test kit Filter #X.

 

That’s it for Step 2, but:

Before you click on your favorite filter number, check out Step 3. So you don’t have to come back:

Step #3: Decide based on non-blue-related preferences

Now you know that blue blockers in Group #X will work for you.

But:

You still have to choose between the blue blockers in that Group.

To make your final decision consider your preferences like:

– frame style
– different coatings
– price
– etc.

 

TIP 1: Find this info by clicking on the links in the Where to buy glasses online column (on the right).
TIP 2: We do recommend Anti Reflective coating (AR) to reduce the veiling glare problem.

Why some popular glasses that block blue light aren’t featured

For example, brands like Felix Gray, LifeArt, Ambr, Pixel, Cyxus, MVMT, Oakley, QUAY blue light glasses, Warby Parker 

They are not featured for one simple reason:

We couldn’t find their spectral transmission profiles.

So we cannot match them to your blue light sensitivity.

Facts about Blue light & blue light filter glasses

The science about the impact of blue light on our body is very rich. And complex.

Below is a peek into it – made as simple and brief as possible.

What is blue light?

Blue light is a color in the visible light spectrum.

Blue light wavelengths: ~380 – ~500nm.

Blue light carries more energy than other visible light colors.

Why has blue light become a problem

Because our eyes face excessive blue light when performing sharp vision tasks. A very unlikely situation in nature.

And:

Because often we are exposed to blue light when it is not natural.

Unnatural exposure to blue light is due to:
– energy saving lighting and
– digital screens.

Blue light is not only bad

For once, it is a beautiful color! 🙂

Also:

We need blue light during the day to function well.

For example:

There is lots of blue light in sunlight. And much less on a cloudy day.

Now:

You know how difficult it is to be upbeat and cheerful on a dark, grey cloudy day :(. It’s the lack of blue light.

But as soon as the sky clears up you feel much, much better! It’s blue light doing it!

Another example:

When the level of blue light goes down:
– in the afternoon and especially
– after sunset
we become sleepy – or at least we used to (before energy saving lighting and digital screens).

So blue light helps our body get in sync with the natural rhythm of day and night. (This is particularly helpful when we need to adjust to a different time-zone).

But, there is the bad part

Unnatural exposure to blue light is a problem:

For example:

Too much blue light after sundown may lead to insomnia.

Another example:

Excessive blue light in tasks that require sharp vision causes:

– eye strain
– difficulty focusing
– dry eyes
– headaches and migraines
– neck and back pains, etc.

This is why extended hours of digital screen viewing are so tiring (see more on this below).

For more on blue light see this 4 min. interview with Prof. Fontaine:

 

Why blue light affects some people more?

This is a key question. It helps understand:

– Why anti blue blocking glasses work for some people but not for others, and
– Why different people need different color blue light filters.

We don’t all have the same sensitivity to blue light.

There are several reasons for these differences. Most result from how our brain processes light signals.

It is complex stuff. And, still not well understood [Measuring and using light in the melanopsin age (2014)].

 

But we’ll focus on a reason that is one of the best researched – macular pigment [The Visual Effects of Intraocular Colored Filters (2012)].

 

What is macular pigment

Macular pigment is a natural blue light filter in our eyes:

blue filter - eye anatomy - macular pigment

One of its principal functions is to stop blue light from reaching the macula (or fovea).

We’ll get to the macula in a minute …

Now:

Your macular pigment may block:
– a lot of blue light
– very little of it, or
– somewhere between the two extremes.

If you are in a hurry see at least the first third of this 9 min video by Prof. Beatty:

 

So, your macular pigment might look like this:

eye strain headache screen glare - MPOD levels 3D

Examples of different macular pigment profiles [Macular pigment imaging in AREDS-2 participants: an ancillary study of AREDS-2 subjects enrolled at the Moran Eye Center (2013)]

The worst part about it:

It is difficult to have macular pigment measured. Except in a few highly-specialized research labs.

Now:

Research suggests only about one out of five people has an effective macular pigment:

Macular pigment, MPOD, blue light glasses

So, the rest of us (4 out of 5 people) need blue blocking glasses.

But not everyone the same strength anti blue light glasses.

 

TIP: We can also try to strengthen our macular pigment. Macular pigment supplements improve it in most people.

 

Now:

Let’s see what happens when excessive blue light gets past our macular pigment – to the macula.

 

What is the macula

The macula is a tinny spot on the retina that captures sharp vision images.

Now:

It is sensitive to red and green light only. There are no photoreceptors for blue light at its center (fovea centralis):

red green and blue cones arangement at the macula

The distribution of the cones – photoreceptors for red, green, and blue light at the Macula. Represented by red, green, and blue dots. (Source: Rochester Institute of Technology)

But it gets worse:

Blue light reaches the macula out of focus. So our eyes strain more to see well.

And:

– Blue light may damage our sharp vision cells at the macula (as explained by Prof. Beatty in the video).

Bottom line:

The blue light that gets to the macula is:
– useless
– annoying, and
– potentially harmful.

What excessive blue light at the macula feels like

This is how you might feel if there is too much blue light getting to your macula:

– eye strain
– glare
– difficulty focusing
– dry eyes
– headaches and migraines
– neck and back pains
and many other symptoms

 

NOTE: We use central vision when viewing digital screens.
If you are like most, you use a white background. Yet, to display white lots of blue light must be emitted.
Imagine what that blue light does to your eyes!

 

So, now you are could be thinking:

That’s great. But:

 

My problem is NOT computer eye strain!?

Blue blockers also help fix problems like:
– Insomnia
– Migraines
– Glare and light sensitivity (photophobia)
– Age-related Macular Degeneration – AMD (an unproven hypothesis).

We cannot look at all these in detail. Unfortunately.

But, if interested, here are some places to get you started:
Glasses that block blue light help improve sleep
Migraines are more likely provoked by blue light
Blue light is more likely to cause glare and light sensitivity
Blue light is more likely to cause retinal cell death – AMD

So summing it all up:

 

What are the best blue light blockers?

The best blue blockers are those that match one’s blue light sensitivity.

Blue light sensitivity varies from person to person. It depends on blue blocking strength of one’s macular pigment.

NOTE: Higher blue blocking effectiveness is not necessarily better.

 

Do blue light glasses work?

Blue light glasses do work for about 4 out of 5 people. But their blue blocking level must match each person’s blue light sensitivity.

 

Do I need blue light blocking glasses?

You cannot be sure whether you need anti blue ray glasses unless you try wearing them. This is because you cannot know your blue light sensitivity.

 

What are blue blocker glasses?

Anti-glare blue light blocking glasses reduce/filter blue light. They should block blue light more than the rest of visible light.

For example:

Suppose my screen emits 100 units of blue light at 445nm towards my eyes:
– Without glasses, my eyes take in all 100 units.
– WITH blue blocking glasses my eyes only take in 30 units of blue light at 445nm. That’s supposing the glasses block 70% of blue light at 445nm.

Such blue light glasses might block only about 10% of the rest of visible light (~500nm – ~760nm).

 

How do you know how much blue light is blocked?

You need to look at glasses’ spectral transmission profile.

It describes how much light they transmit. And how much they block. At each wavelength!

 

How to read spectrograms?

The easiest way to grasp spectral transmission data is in a spectrogram.

Its curve tells you what is the blue-blocking rate at each light wavelength.

The image below explains how to read a spectrogram. (It’s the spectral transmission profile of pink FL-41 blue block glasses).

Blue light filter tester-how to interpret spectrograms

 

Do yellow glasses block blue light?

Yes, yellow glasses block blue light.

But:

You can’t judge their blue blocking range only based on their color. The difference between two yellow filters can be huge.

For example:

The two filters below are both yellow (see the light grey box under the graph).

Now:

Note the big difference in how much blue light they block!

Comparing spectral transmission of two yellow tints

Source: Adapted from Lee FILTERS

The same may be true for other blue blocking lens tints.

 

Do blue light glasses have to be yellow?

No. Blue blockers don’t have to be yellow.

Blue blocker lenses that use tinting technology are:
– yellow,
– pink-ish tinted: the anti-fluorescent, anti migraine FL-41 tint
– amber,
– orange, or
– red.

Clear-lens blue light filter glasses may use:
– blue light reflective coating – produces a blue reflection on the lens, or
– blue light absorbing monomer – blue blocker lens appear almost clear.

Now:

Blue-blocking rate depends on the filter color. As does color distortion:

 

Do blue blocker lenses distort color?

Yes, they do. You can’t block blue light and see it too. Obvious, right?

But:

Glasses that block very little blue light are almost clear

Color distortion of “clear” blue blockers is minimal. They change:
– blue to a darker blue
– white to off-white.

Find examples of such glasses among the Group #7 blue blockers.

Anti blue ray glasses that block all blue light must be orange (or red)

Color distortion of orange (or red) glasses is significant. They change:
– blue to black and
– white to orange (or red).

Find examples of such glasses among the Group #1 (or #0) blue blockers.

Yellow and Amber glasses fall between:
– yellow glasses are closer to clear-lens blue blockers
– amber glasses are closer to orange blue blockers.

 

Do computer glasses have a prescription?

Computer glasses may or may not have a prescription. Their principal property is that they block blue light.

In some cases computer glasses do have a prescription:
– People who need prescription glasses need it also on their computer glasses.
– Some people find relief with a small power add to their computer glasses. Even though they otherwise don’t need prescription glasses.
