Blue Light Glasses Over Glasses: Clip-Ons & Fit Overs Explained

If you already wear prescription glasses, you’ve probably wondered whether you can add blue light protection without switching pairs. 

The short answer? Yes. You can use clip-on blue light filters that attach right over your existing glasses.

These filters act like a shield, blocking high-intensity blue light before it reaches your eyes. The result is simple: less digital eye strain, reduced glare, and better sleep quality after screen time.

In this post, we’ll walk through what blue light glasses over glasses actually are, how they work, what to look for before buying, and whether they’re worth the upgrade.

Let’s dive in. 

What Are Blue Light Glasses Over Glasses?

Blue light glasses over glasses means you put an additional layer of blue light protection on top of your existing glasses (Typically prescription lenses). 

The goal is simple: The additional filter blocks most of the blue light wavelengths (around 400 - 500 nm) that come out of digital devices like TVs and laptops. 

These wavelengths often cause digital eye strain, eye fatigue, and sleep issues, especially when consumed later at night or for long periods. 

Some protective lenses even filter out the green light wavelengths since they can also play a part in keeping your body alert when it’s supposed to rest. 

There are essentially two types of blue light filtering technologies that fit over your existing prescription glasses (Or any glasses):

• Clip-on blue light glasses
• Fit over blue light glasses 

Using these additional pairs gives you blue light protection without sacrificing your prescription vision.

Why Blue Light Protection Matters

If you spend several hours of a typical day looking at a screen, whether it’s your phone, laptop, or even TV, you’re continuously bombarded with high-intensity blue light wavelengths. 

Here’s what prolonged exposure can cause:

• Digital Eye Strain: Burning, dry eyes, or blurred vision after long hours of screen time
• Headaches: Often triggered by the constant glare and flicker from LED screens
• Sleep Disruption: Blue light can suppress melatonin, making it harder to fall asleep

Wearing blue light clip-ons or fit-over blue light glasses is probably the best strategy to protect your eyes and overall health in the long run. 

Fit-Over vs Clip-On Blue Light Glasses

Let’s introduce you to the two common types of blue light glasses over glasses. Fit-over frames and clip-on lenses do the same job, but they suit different preferences. 

Here’s a quick comparison:

Fit-Over Blue Light Glasses: Full Coverage Protection

Fit-over blue light glasses are essentially larger frames built to slide right over your prescription glasses.

Pros:

• Covers the entire lens area, offering maximum protection from blue light and glare
• Great for users who switch between digital and non-digital tasks often
• Ideal if you wear thicker or wide prescription frames

Cons:

• Can feel a bit bulky for some users
• Might not match everyone’s style preference

If comfort and protection matters to you more than style and fashion, fit-over blue light glasses are a great fit for your lifestyle.

Clip-On Blue Light Glasses: Lightweight and Discreet

Clip-on blue light glasses attach directly to your prescription lenses; think of them like sunglasses clips, but for blue light protection. 

Pros:

• Lightweight and easy to carry
• Don’t change the look or feel of your prescription glasses much
• Often affordable than fit-over styles

Cons:

• May not fit well on curved or thick frames
• May not fully cover the edges 

They’re a great pick for people who value portability and minimalism. You can clip them on when working, then remove them instantly when you’re done.

How to Choose the Right One for You

Here’s a quick way to decide:

• Want maximum protection and don’t mind a slightly larger frame? Go for fit-overs!
• Already have a comfortable pair of prescription glasses and want a lightweight add-on? Pick clip-ons!

And make sure to check:

• Size compatibility: The fit-over should match your prescription glasses dimensions
• Lens quality and additional protection: Go for anti-glare and scratch-resistant coatings
• Color tint: Clear or slightly amber lenses are best for all-day screen use

Maintenance Tips for Blue Light Glasses Over Glasses

Taking care of your blue light glasses’ lenses, whether they’re clip-ons or fit-overs, extends their lifespan and keeps your vision clear. 

Here’s how you do it: 

• Clean daily with a microfiber cloth to remove smudges
• Avoid harsh chemicals that could strip coatings
• Store properly in a protective case to prevent scratches
• Check clips and hinges regularly if you’re using clip-ons

Are Blue Light Fit-Over Glasses & Clip-Ons Worth It?

Yes, they’re an investment in your long-term health and eye comfort, especially if you’re staring at screens for more than 6 hours a day. 

You’ll likely feel the difference within 1 to 2 weeks of wearing them. Whether you go for fit-overs or clip-ons, blue light glasses over glasses help you:

• Work for longer periods without straining your eyes 
• Get better-quality sleep
