Why Color
Dogs look up at the sky and at us from a much lower angle than we do — so on sunny walks, their eyes take in more glare than ours. As dogs get older, the iris often controls light less precisely too, so squinting becomes more common, even in otherwise healthy dogs.
Parks & open trails
Bright, open ground
Strong sunHow it helps
UV and glare protection for daytime walks.

Mirrored tint softens the intensity of bright, reflected light — not by blocking everything, but by cutting down what gets through.

Blocks 99.9% UVA/UVB, built into the lens material itself — the same standard as every Kyunglas lens.

Built to handle strong sun, not to replace a clear lens after dark.

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
UV and glare protection for daytime walks.
Color Lens is designed for daytime walks over 20 minutes in strong sun — it isn't a night lens.

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.
“Tinted goggles wouldn't be a good choice on evening walks or doing search and rescue in the dark.” — Dr. Marnie Ford, DVM, DACVO (board-certified veterinary ophthalmologist)
| Sizes | Small, Medium, Large |
|---|---|
| Frame colors | White, Black, Pink, Yellow |
| Lens colors | 7 lens colors (see Lens Technology) |
| Sets | Color Lens + Frame · Clear + Color Lens + Frame |
Small and Medium offer all 4 frame colors and all 7 lens colors. Large is available in White, Black, and Pink frames, and Tulip Purple replaces the standard Purple lens option.
A tinted lens shouldn't be chosen by color alone — what actually matters is how much light it lets through.
Most Kyunglas color lenses use a near-neutral tint — the mirror coating changes how the lens looks from the outside, but what your dog actually sees through it stays close to natural. The real difference between colors is brightness, measured as VLT (Visible Light Transmission).
| Lens color | VLT | Category |
|---|---|---|
| Red | 28.9% | CAT2 |
| Smoke | 26.6% | CAT2 |
| Purple | 23.8% | CAT2 |
| Tulip Purple | 21.2% | CAT2 |
| Gold | 18.2% | CAT2 |
| Green | 16% | CAT3 |
| Blue | 14.6% | CAT3 |
CAT2 — lighter · CAT3 — darker. Choose by how strong the sunlight is where you walk — not by which color looks best.

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.
| 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.
Dog faces vary widely in width, muzzle length, and contour. That's why fit can't be solved with straps alone.

New gear takes time, and adjustment varies by dog.

FAQ
No — Color lenses reduce UV and glare during the day, which also makes them darker at night. Switch to Clear after dark, or choose the Clear + Color set to swap easily.
Choose based on brightness, not color. Each lens has a VLT (Visible Light Transmission) rating — the lower the number, the darker the lens. Gold, Tulip Purple, Purple, Smoke, and Red sit in the CAT2 range (lighter); Green and Blue sit in CAT3 (darker). For dogs very sensitive to strong light, such as dogs with iris atrophy, consider CAT3 Green or Blue first.
Not the way it looks from the outside. Most Kyunglas color lenses transmit light in a near-neutral tone, so the view through the lens stays close to natural — brightness is what changes, not color.
Yes — 99.9% UVA and UVB, built into the lens material itself, the same as every Kyunglas lens.
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.
Daytime UV and glare protection — pair with Clear for round-the-clock eye comfort.
