Flip-up hinge lifts the lenses out of the way when you don’t need them. Two options: Amber (50% blue light filtering) for daytime screen use and Orange (99% blue light filtering) for nighttime use and sleep support. Fits most glasses with a bridge width up to 0.5”. Protective case included.

Good to know
  These are blue light filtering clip-on lenses. Because blue light is part of the EMF spectrum, filtering it also reduces your daily EMF exposure. They filter blue light emitted by screens (computers, phones, tablets, TVs, and LED lighting). For shielding against RF and ELF EMF radiation from your devices, see DefenderShield’s phone cases, laptop shields, and clothing - these clip-ons do not contain Ultra Armor® or silver shielding fabric. The clip-on mechanism fits most standard prescription glasses with a bridge width up to 0.5”. If your glasses have a thicker bridge or an unusual shape, the clip may not attach securely.

Description

Blue Light Filtering for Your Prescription Glasses

👓 Clip On, Flip Up, Take Off — No Second Pair Needed

If you wear prescription glasses, you know the tradeoff: either buy a separate pair of blue light glasses (and swap between two pairs all day) or skip blue light filtering entirely. These clip-on lenses eliminate that choice. Pinch the prongs to open, clip them onto the bridge of your existing glasses, and you have blue light protection on top of your prescription. When you don’t need the filtering, flip the lenses up on the hinge — they rest above your line of sight until you flip them back down. When you’re done, unclip them and stow them in the included protective case.

Two Filtering Levels — Daytime and Nighttime

☀️ Amber (50%) for Day · 🌙 Orange (99%) for Night

The Amber lens filters 50% of blue light. The slight amber tint keeps colors close to natural, making it practical for daytime work, reading, browsing, and driving in overcast conditions. The Orange lens filters 99% of blue light. The deeper tint is designed for evening and nighttime screen use, when blue light has the strongest effect on circadian rhythm. Reducing blue light exposure before bed can support the body’s natural transition to sleep. Choose one for your primary use case, or keep both on hand for day and night coverage.

Built to Last on Top of Your Daily Glasses

🔧 Polycarbonate Lenses · Stainless Steel Frame · 3 oz

The lenses are polycarbonate — lightweight, impact-resistant, and optically clear. The nose bridge and hinge are stainless steel for corrosion resistance and long-term durability. At 3 oz total, the clip-ons add minimal weight to your glasses. The flip-up hinge operates smoothly without loosening over time, and the clip prongs grip securely without scratching. A protective hard case is included for travel, commuting, and pocket carry.

How to use

Getting Started

1. Check the fit. These clip-ons fit most standard prescription glasses with a bridge width up to 0.5” (approximately 13 mm). Measure the bridge of your glasses — the horizontal bar that connects the two lenses across your nose — to confirm it is 0.5” or narrower. Wider bridges may not clip securely.

2. Clip on. Pinch the prongs on either side of the nose bridge to open them. Position the clip-on lenses over your existing lenses so both pairs are aligned. Release the prongs — they grip the bridge of your glasses and hold the clip-ons in place.

3. Flip up when not needed. The hinge at the bridge allows the clip-on lenses to flip upward, resting above your line of sight. Use this when you need your full, unfiltered view — then flip back down when you return to a screen.

4. Remove and store. Pinch the prongs again to unclip. Store in the included protective case to prevent scratches and bending.

When to Use Each Lens

Amber (50%) — daytime: Working on a computer or laptop, browsing on a phone or tablet, reading under LED or fluorescent lighting, driving in overcast or rainy conditions. The slight tint allows most natural colors to pass through.

Orange (99%) — nighttime: Using screens within 2–3 hours of bedtime, gaming sessions, watching TV in a dark room, or any extended evening screen time. The deeper tint filters nearly all blue light, supporting the body’s natural circadian transition toward sleep.

Care Instructions

• Clean the lenses with a soft microfiber cloth. Do not use paper towels, tissues, or abrasive materials.

• For stubborn spots, rinse with water and dry with a microfiber cloth. Avoid chemical lens cleaners unless they are specifically designed for polycarbonate.

• Store in the included protective case when not in use to prevent scratches and hinge damage.

• Do not bend the clip prongs forcefully — they are designed to grip a bridge up to 0.5”. Forcing them wider may weaken the spring mechanism.

The clip mechanism is so wide that it’s in my line of sight, and is too visually distracting for me to wear them.

Hi Theresa, thank you for your feedback. We're sorry to hear the clip mechanism isn't working well for you. We appreciate your input and will consider it for future designs. Please feel free to reach out if you'd like to return them!

A good deal for the money. I still prefer the Defender Shield Fit-over style but these clip-ons are super handy to keep in my purse.

The only issue is that it is a little bit heavy on the nose.

We purchased this product at the recommendation of a doctor. I ordered two of the orange lenses and one of the lighter ones. My husband (age 82) did not like the orange lens so I returned it and ordered the lighter ones. I (age 76) use one of each…the orange for TV and the lighter for reading.
Regarding the product…the clip to hold the lens on my glasses is sometimes hard to maneuver with slightly arthritic fingers and it’s cumbersome to keep these clean…they do not shine up like my glasses do. My clip-on sunglasses from my optometrist are much easier to use.

I like that they clip bonds, but I do think they’re charging way too much for these. They should still be able to make money at about 20 bucks.

Doesn’t fit well on glasses. Not tight on the glasses. Instructions would be nice because I think I’m doing it wrong. But product itself is great and definitely reduces blue light. I just need to fit it better on my glasses

FREQUENTLY ASKED QUESTIONS

Blue Light Blocking Clip-On Lenses FAQ

They fit most standard prescription glasses with a bridge width up to 0.5” (~13 mm). The clip prongs pinch onto the horizontal bridge that connects your two lenses. If your bridge is wider than 0.5”, the clip may not grip securely. Wrap-around frames, frameless glasses, and some oversized styles may not be compatible. Measure your bridge width before ordering.

Filtering percentage and intended time of day. The Amber lens filters 50% of blue light with a slight tint that keeps colors close to natural — designed for daytime use (work, reading, driving in overcast conditions). The Orange lens filters 99% of blue light with a deeper tint — designed for nighttime use when blue light has the strongest effect on circadian rhythm and sleep preparation.

Yes - blue light is a form of EMF radiation. Visible light - including blue light - sits in the high-energy, short-wavelength part of the electromagnetic spectrum known as HEV (High Energy Visible) light. By filtering these wavelengths from screens, LED lighting, and other devices, these lenses reduce your daily EMF exposure and support healthier eyes and better sleep. For shielding against RF and ELF EMF radiation from your devices, see DefenderShield’s phone cases, laptop shields, and clothing.

Yes. The stainless steel hinge at the bridge allows the lenses to flip upward so they rest above your line of sight. Flip them down when you return to a screen, flip them up when you need an unfiltered view. You only need to unclip them when you’re done using them.

At 3 oz, the clip-ons add minimal weight to your prescription glasses. The stainless steel frame distributes the weight evenly across the bridge. Most users can wear them comfortably through a full workday or gaming session without noticeable fatigue.

The Amber (50%) lenses allow most natural colors and contrast to pass through, making them practical for driving in overcast or rainy conditions. They may help reduce glare from oncoming headlights during cloudy daytime driving. The Orange (99%) lenses are not recommended for driving — the deep tint significantly alters color perception and may affect your ability to see traffic signals and brake lights accurately.

DefenderShield’s other blue light glasses are complete eyewear with their own frames and lenses — designed for people who do not wear prescription glasses or who want a dedicated pair. The clip-ons attach to your existing prescription frames, giving you blue light filtering without replacing your everyday glasses. Both offer the same 50% and 99% filtering levels.
