Learn how to replace Rex Specs V2 lenses in minutes. Follow our step-by-step guide to swap scratched or tinted lenses and keep your dog's goggles clear and protected.
Quick answer
To replace Rex Specs V2 lenses, gently pry the old lens out from the frame, align the new lens with the frame's grooves, and press it in until it clicks. Always use the correct lens size for your goggle and handle lenses by the edges to avoid scratches.
Scratched lenses can reduce your dog's vision and defeat the purpose of protective goggles. Replacing the lenses in your Rex Specs V2 goggles is a simple task that takes only a few minutes and requires no special tools.
Whether you're swapping in a tinted lens for sunny hikes or replacing a worn clear lens, knowing how to do it correctly ensures a secure fit and long-lasting protection. Follow these steps to get it right every time.
Before You Start: Know Your Lens Size
Rex Specs V2 goggles use lenses that come in a specific size for each goggle model. Using the wrong size can cause gaps or a poor seal, so check your goggle's size before ordering. If you have a Small Wide Goggle, for example, you'll need the corresponding V2 lens size.

It's also wise to inspect the new lens for any debris or dust before installation. A clean lens not only improves visibility but also prevents scratches that can happen if particles are trapped against the frame.
- Match the lens size to your goggle model—check the goggle's size label before purchasing.
- Clean your hands and the lens surface to avoid transferring oils or dirt.
- Handle the lens by the edges to keep the center clear of fingerprints.
Step-by-Step Lens Replacement
Start by placing your dog's goggles on a flat, stable surface. Press gently on the back of the current lens to pop it out of the frame. You may need to use your thumb to apply even pressure—avoid prying with sharp objects, which can damage the frame.
Once the old lens is out, compare it with the new one to confirm the size and shape. Align the new lens with the frame's front opening, ensuring the curved side faces outward. Press the lens into the frame starting from one edge, then work your way around, pressing firmly until it seats evenly.
After installation, give the lens a gentle push in the center to make sure it's secure. Run your finger along the frame edges to check for any gaps or uneven seating. If the lens pops out easily, reinsert it and press harder along the entire perimeter.
- Apply even pressure—pressing one corner first can warp the lens.
- Check that the lens is flush with the frame on all sides.
- If the lens doesn't sit flat, remove and realign it instead of forcing it.
Common Mistakes to Avoid
One common mistake is using the wrong lens size. Lenses are not universal across all Rex Specs goggles, and a lens meant for a standard goggle won't fit a Small Wide Goggle. Always verify compatibility before purchasing.
Another mistake is replacing lenses in a dusty environment. Dust and grit can get trapped between the lens and frame, causing scratches over time. Work in a clean area and clean the frame's grooves before inserting the new lens.
Finally, don't use excessive force. While lenses are impact-resistant, they can crack if bent too much. Press with steady, even pressure rather than swinging your hand to force it in.
Your Lens Replacement Checklist
- Confirm lens size: Check the size of your Rex Specs goggle and order the matching V2 Replacement Lenses. Using the wrong size can compromise protection and fit.
- Remove the old lens: Press the back of the lens gently to pop it out without prying. Avoid sharp tools to prevent frame damage.
- Install the new lens: Align the lens with the frame and press evenly around the edges until it clicks into place. Ensure the lens sits flush to keep protection intact.
Lens Options and What to Know
- V2 Replacement Lenses: Available in nine different shades to meet your dog's needs, and engineered from premium materials to provide protection from anything your dog may encounter. All lenses are impact resistant and UV 400 rated, blocking 99% of harmful UVA and UVB rays. Choosing the right tint can improve visibility in different lighting conditions, while knowing the shade options helps you pick the lens that suits your dog's activities.
- Small Wide Goggle: Designed to fit dogs with a short nose and wide, flat face like a French Bulldog or Pug. Dogs that fit this goggle still need a nose about 1 inch in length. If your dog wears a Small Wide Goggle, you'll need the corresponding V2 lens size for that frame. Double-check sizing before ordering replacement lenses to ensure a proper fit.
Replacing your Rex Specs V2 lenses is a quick task that keeps your dog's goggles performing at their best. By following these steps and choosing the right lens size, you'll maintain clear vision and lasting protection for your adventure companion.
