Why Active
Light changes on every walk.
Outdoor UV conditions can change during the same day. A fixed-tint lens keeps the same tint. Active changes with UV exposure.
Open SunShadeCloudy ConditionsChanging Outdoor UV
How it helps
One lens that follows the light.
Lighter when UV is low, darker as UV exposure increases.
UV-Responsive Tint
Lighter when UV is low, darker as UV exposure increases.
UV-Blocking Lens Material
UV-blocking material is built into the lens itself, not added only as a surface coating.
Fewer Lens Changes
Automatically adjusts its tint to outdoor UV, so you can enjoy changing conditions without switching lenses.
Photochromic lenses respond to UV exposure, so tint change may be limited indoors or inside a car where UV exposure is lower.

Which lens matches your dog's day?
Choose by routine. Clear suits first wear, cloudy and rainy days, and evening or night walks. Color gives a fixed tint for bright daytime walks and cuts glare. Active adjusts its tint to outdoor UV.

Product information
Outdoor UV conditions can change during the same day.
Active fits outdoor routines where UV exposure changes rather than staying constant — for owners who'd rather use one photochromic lens than choose a single fixed tint.
Active lens
- Photochromic: light → smoke as UV exposure increases
- UV-blocking material built into the lens itself
- One lens instead of a single fixed tint
Built to fit
- Toric lens: different horizontal and vertical curvatures
- 3 sizes, adjustable strap, 7-Point Fit
- Refined through 1,000+ fittings
Eye protection starts with healthy eyes.
KYUNGLAS is designed for everyday eye protection, from healthy dogs to those who need extra care. Owners also use it to help protect dogs with cataract concerns, iris atrophy, conjunctivitis, keratitis, dry eyes, or limited or lost vision.
| Sizes | Small, Medium, Large |
|---|---|
| Frame colors | White, Black, Pink, Yellow |
| Lens types | Active, Active Pro |
| Sets | Lens + Frame · Lens + Color Lens + Frame |
Small and Medium offer both Active and Active Pro, each with the full Color Lens pairing lineup. Large is available in White, Black, and Pink frames; Tulip Purple replaces the standard Purple lens option when pairing with a Color Lens.
How photochromic lenses change
Photochromic lenses respond to UV exposure by changing tint.
| Lens | How it changes with UV |
|---|---|
| Active | Light → Smoke |
| Active Pro | Light + Rose Gold mirror → Darker + more visible mirror |
Both Active and Active Pro use this photochromic response. Active Pro uses the same photochromic response with a Rose Gold mirror finish. Photochromic lenses respond to UV exposure, so tint change may be limited indoors or inside a car where UV exposure is lower.
Lens structure
UV-blocking material
- UV-blocking material is built into the lens itself, not added only as a surface coating.
Toric lens
- Horizontal curve — wide wraparound coverage for a broad field of view
- Vertical curve — a 3D profile shaped for a curved goggle structure
A protective lens shouldn't make the world feel smaller.
Active or Active Pro?
Both are photochromic. The difference is the lens finish.
| Lens | Active |
|---|---|
| Type | Photochromic |
| Behavior | Light → Smoke |
| Finish | No mirror coating |
| Choice reason | For owners who prefer a clean, neutral photochromic lens. |
| Lens | Active Pro |

| Type | Photochromic + Rose Gold Mirror |
| Behavior | Light with subtle Rose Gold mirror → Darker with more visible mirror |
| Finish | Rose Gold mirror coating |
| Choice reason | For owners who want photochromic function with a Rose Gold mirror finish. |
Is Active Pro stronger than Active? No. The main difference is the Rose Gold mirror finish.

Built on the ANSI criteria used for human protective eyewear and goggles — and tested even more rigorously through our 19-test quality framework. This is our own in-house testing, with methods and requirements based on KS G ISO 12312-1:2024 and KS G ISO 12312-3:2024, not an independent or third-party certification.
Choose your size
| Size | Head circumference | Weight reference |
|---|---|---|
| S Small | 22–29 cm / 8.7–11.4" | 3–7 kg / 6.6–15.4 lb |
| M Medium | 30–38 cm / 11.8–15.0" | 7–16 kg / 15.4–35.3 lb |
| L Large | 39–46 cm / 15.4–18.1" | 16–35 kg / 35.3–77.2 lb |
Measure head circumference by passing the tape under your dog's chin and wrapping it once around the head, between the eyebrows and the ears, closer to the eyebrows. It is not a horizontal loop around the top of the head only. Head circumference decides the size; weight is a reference only. Falling within a size range is a starting point — fit can still vary by eye spacing and muzzle shape.
Short Muzzle options are not currently available for direct purchase through our global store. Fit varies depending on your dog's facial structure and proper strap adjustment. If you're considering KYUNGLAS for your short-muzzled dog, please contact us first so we can assess the fit and discuss available options.
7-Point Fit
Dog faces vary widely in width, muzzle length, and contour. That's why fit can't be solved with straps alone.

FAQ
Questions we hear most.
What is the difference between Active and Active Pro?
Both are photochromic. Active changes to smoke; Active Pro adds a Rose Gold mirror finish.
Is Active Pro stronger than Active?
No. The main difference is the Rose Gold mirror finish.
Does the lens change indoors or inside a car?
Photochromic lenses respond to UV exposure, so tint change may be limited indoors or inside a car where UV exposure is lower.
Can I add a Color Lens?
Yes. Active and Active Pro can each be paired with a Color Lens via Set Configuration.
Which lens suits a dog with an eye condition?
It depends on your dog's eye condition and light sensitivity. For strong light sensitivity, such as iris atrophy, consider a fixed CAT3 Color lens (Green or Blue). Clear provides protection without a dark tint, making it useful for first wear, cloudy or rainy days, and evening walks. Active adjusts to UV, so its tint may not provide consistent shading in bright, low-UV conditions. KYUNGLAS is protective eyewear, not a treatment. If your dog has acute eye inflammation or a corneal injury, consult your veterinarian before use.
