4 Reasons why blue light glasses protect your eyes from screens:

1. They block blue light, which dries your eyes every hour

The blue light from your screens evaporates the tear film in your eyes.


The tear film is the layer

of water that keeps your eyes moist.

 

Without it, your eyes become dry, burn. They turn red.

 

This is what happens:

 

Your computer and phone emit blue light. That light enters your eyes. 


It heats the surface. Your tear film evaporates faster. 


Your eyes become dry. And you start to feel that burning sensation.

 

You take out the eye drops. They give you relief for 20 minutes. Then the burning returns. 


Because you didn't fix the problem. You only masked the symptom.

 

But when you block that blue light during your workday, something incredible happens:

 

Your tear film stops evaporating so quickly. Your eyes maintain their natural moisture. Just like before spending 8 hours in front of screens. 


Just as they should naturally be.

 

The result?

 

You work 8 hours without drops. Not 3 drops a day, 

not 6. Zero drops.


Your eyes function as nature designed them.

2. Dry eyes create a cycle of dependency that you can't escape

When your eyes are dry, you do the logical thing: you put in drops.

 

The drops relieve you. For 20 minutes. Maybe 30.

Then the burning returns. You put in more drops. And more. And more.

 

But here's the problem:

 

The drops only treat the symptom. They don't fix the cause.

 

It's like having an open faucet flooding your house... and your solution is to dry the floor every hour. You don't turn off the faucet. You just dry.

 

The result?

 

You need more and more drops. Your wallet empties (€25-50 per month). 


Your eyes remain just as dry. And you never break the cycle.

 

But when you block the blue light that causes evaporation, you turn off the faucet.

 

You don't need to dry the floor every hour. Because it's no longer flooding.

 

Your eyes maintain their natural moisture. 

 

The drops stay in the drawer. 


And you finally break the cycle.

3. They improve the natural moisture of your eyes by 80%

Here's what really happens: instead of having dry, red eyes after 5 hours, your eyes maintain their moisture for 8-9 hours. 


And instead of using drops every 2 hours all day, you go days without touching them.

 

That's why this matters so much.

 

Right now, you're probably working 8 hours but you can only last
4-5 without your eyes burning.

 

You always have drops in your pocket. You use them 4, 5, 6 times a day. 


And at the end of the day your eyes are red, irritated, completely exhausted.

 

The reason is simple: the blue light from screens is constantly evaporating your tear film.

 

Your eyes don't have time to recover. Natural moisture disappears faster than your body can replenish it. 

 

You get stuck in a cycle of dryness, burning, drops. Dryness, burning, more drops.

 

This is what you're missing:

 

Constant natural moisture:


→ Your eyes maintain their protective layer
→ No constant evaporation
→ The burning doesn't appear every hour
→ Irritation disappears

 

Eyes that function as they should:


→ You don't need to interrupt yourself every 2 hours
→ You can concentrate without distractions
→ You don't end the day with red eyes
→ Natural comfort returns

 

When blue light evaporates this moisture, none of that protection happens.


There's no real relief.
No rest for your eyes.

 

But when Rauwax blocks that light, everything changes.

 

Workdays are different. No burning at 3 in the afternoon. 

You don't have to interrupt yourself every hour to put in drops. 

Your eyes feel truly rested, and that comfort lasts all day without failing you in the mid-afternoon.

 

Before Rauwax: 8 hours working, perhaps 4-5 comfortable hours before the burning.


With Rauwax: 8 hours working, 8 hours of comfortable eyes that work well.

 

The glasses not only reduce burning: they protect the natural moisture that really matters.

4. They stop the burning sensation that appears every 2 hours

You know the pattern.

 

You start work at 9 AM. Fresh eyes. All good.

 

11:00 AM - First drop. Your eyes start to bother you.

 

1:00 PM - Second drop. The burning returns.

 

3:00 PM - Third drop. Now it's constant.

 

5:00 PM - Fourth drop. It doesn't even completely relieve you anymore.

 

It's not just annoying. It's exhausting.

 

Every time you have to stop to put in drops, you lose focus.  


You lose your train of thought. And it takes 5-10 minutes to refocus.

4-6 interruptions a day.  

 

That's 20-60 minutes lost just because of
your dry eyes.

 

But here's the real problem:

 

The burning doesn't come out of nowhere. It comes from blue light constantly evaporating your tear film.

 

With each passing hour, your eyes get drier. The burning increases. The drops only provide temporary relief.  

But the cause remains.

 

It's like trying to fill a bucket with a hole in the bottom. You can keep pouring water (drops), but it will keep emptying.

 

With Rauwax, you plug the hole.

 

Blue light is blocked.  

 

Your tear film stops evaporating as
quickly.  

 

Your eyes maintain their natural moisture. And the burning simply... doesn't appear.

 

Not at 11:00 AM. Not at 1:00 PM. Not at 3:00 PM.

 

The result?

 

You work from 9 AM to 6 PM without interruptions.  

 

Without drops.  

 

Without losing focus
every 2 hours.  

 

Just you and your work.

 

That's what it means to have eyes that work as they should.

But here's where most people get confused:

Which color should I use?

Yellow or red?

Good question. And this is key.

 

Yellow lenses block blue light (400–480 nm) but let other wavelengths pass through. They are perfect for use during the day and in the afternoon: they protect your eyes while you work, without making you drowsy.

 

Red lenses block blue light and the green spectrum (400–550 nm), i.e., the entire range that affects melatonin. These are only for nighttime, 1–2 hours before bed.

 

Here's the problem: most people only buy one pair.


And then one of these two things happens:

 

They buy only the yellow ones: they protect you perfectly during the day, but when you get home and use your phone in bed, your eyes are still exposed to the most intense light that affects your sleep. 

 

 

They buy only the red ones: they protect you perfectly at night, but during the day you can't use them for work because they are designed to block the entire spectrum. 

 

Each one does its job perfectly. 

 

But it only covers half the day. 

 

That's why you need both. 

 

Yellow from 9:00 to 20:00 while you work. 

 

Red from 20:00 to 23:00 before bed. 

 

Rauwax gives you both. You don't have to choose. You don't have to buy again. Complete 24/7 protection from day one.

The RAUWAX system has become an essential part of my work routine. My eyes no longer get dry in the middle of the day, instead of being red and burning for hours. The best investment I've made for comfortable work.

I like that RAUWAX uses certified filters that block 100% of blue light. After months of using drops every 2 hours, I have finally reduced my usage by 80-90%. It feels amazing to work without that constant burning sensation.
