What does photochromic mean?

Photochromic lenses automatically darken in bright light and return to clear indoors. No need to switch between glasses — one pair works in all light conditions.

How long does it take for photochromic lenses to transition?

Most lenses darken within 30–60 seconds in sunlight and return to clear within 2–5 minutes indoors. Temperature affects speed — lenses transition faster in warm conditions.

Do photochromic lenses work inside a car?

Standard photochromic lenses react to UV light, which is blocked by most car windshields. They may not darken significantly while driving. For driving, our driving mirror lens options are a better choice.

Are photochromic safety glasses ANSI rated?

Yes — our Reactor and Kona TT photochromic safety glasses meet ANSI Z87.1 standards for industrial and occupational use, making them suitable for job sites and OSHA-compliant environments.

Can I get photochromic lenses that fit over my prescription glasses?

Yes — the Outrigger OTG is available with photochromic lenses and fits over most prescription frames, giving you light-adjusting protection without the cost of prescription photochromic lenses.

How long do photochromic lenses last?

With normal use, photochromic lenses typically last 2–3 years before the transition effect begins to fade. Avoid leaving them in a hot car or in direct sunlight for extended periods to maximize lens life.

What's included in a Spits Eyewear Kit?

Each kit includes a curated selection of Spits eyewear — typically a pair of safety glasses or sunglasses, a microfiber cleaning cloth, and a protective drawstring bag. Kit contents vary by model, so check the individual kit page for the full contents list.

Are the glasses in the kits ANSI Z87.1 rated?

Yes. All safety eyewear included in Spits kits meets ANSI Z87.1 impact resistance standards, making them suitable for workplace, industrial, and high-activity environments.

Do the kits include lenses with UV protection?

Absolutely. All Spits lenses provide 100% UV400 protection, blocking both UVA and UVB rays — whether you're on a job site or outdoors.

Can I get a kit with bifocal or magnifying lenses?

Yes. Select kits are available with bifocal safety lenses in a range of magnification strengths. Look for the "Bifocal" designation in the kit name, or browse our bifocal safety glasses collection for individual options.

Are these kits suitable for wearing over prescription glasses?

Some kits include OTG (over-the-glass) frames designed to fit comfortably over most prescription eyewear. Check the product description to confirm OTG compatibility for a specific kit.

Do the lenses change in different lighting conditions?

Certain kits feature photochromic lenses that automatically darken in bright sunlight and lighten indoors — ideal for workers and athletes who move between environments throughout the day.

How do I clean and maintain my Spits eyewear?

Use the included microfiber cloth to wipe lenses gently. For deeper cleaning, rinse with lukewarm water and mild soap, then pat dry. Avoid paper towels or abrasive materials that can scratch the lens coating.

What is your return policy on kits?

We accept returns on unused, unopened kits within 30 days of delivery. If an item arrives damaged or defective, contact us and we'll make it right. See our full Returns & Exchanges page for details.
