OTG stands for Over The Glasses. OTG safety glasses are designed to fit over your existing prescription eyewear, giving you certified eye protection without needing to remove your Rx glasses or purchase prescription safety lenses.

Will OTG glasses fit over my prescription frames?

Most Spits OTG models fit over standard adult prescription frames. Frame size matters -- the Escort III fits most medium to large Rx frames, the Slim Jims and Slim Janes are designed for narrower or smaller frames, and the Outrigger's foam-padded design accommodates a wide range of frame depths.

What is the difference between fit-over glasses and foam-padded OTG goggles?

Fit-over glasses (Escort III, Slim Jims/Janes, Enfold) sit over your frames with open sides -- lightweight and comfortable for general workplace use. Foam-padded OTG goggles (Outrigger) add a foam gasket that seals around your face, blocking dust, debris, and wind -- better for outdoor, industrial, or high-particulate environments.

Are Spits OTG glasses ANSI certified?

Only the Outrigger is ANSI Z87.1+ certified for high-impact protection, making it suitable for workplace and industrial environments that require certified eyewear. The Escort III, Slim Jims/Janes, and Enfold are not ANSI rated -- check each individual product page for its specific details.

What is the difference between Slim Jims and Slim Janes?

Slim Jims and Slim Janes are the same narrow fit-over frame -- the Janes version is styled and sized to fit over women's prescription frames, which tend to be smaller and more curved than standard men's frames.

Can I use OTG glasses for shooting or hunting?

All Spits OTG models are suitable for range use. The Escort III and Enfold are popular choices for shooters who wear prescription glasses and need a lightweight, low-profile option that does not interfere with cheek weld or sighting.

Do OTG glasses come with anti-fog lenses?

The Outrigger includes an anti-fog lens coating, which is especially important given its sealed foam gasket design. Other OTG models have open frames that allow more airflow, reducing fogging naturally.

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.
