Frequently Asked Questions

Where is the bifocal zone positioned? The bifocal is at the bottom of the lens, so you look down slightly to read your device while your forward vision stays clear.

Can I swap the lenses? Yes — the Thresher comes with both clear and smoke lenses so you can switch based on conditions.

Are these good for triathlons? Absolutely — the rubber ear locks keep the frame secure through transitions and high-intensity efforts.

Cleaning Spits Eyewear safety glasses is essential to keep them in good condition and maintain their effectiveness. First, rinse the glasses with cold or warm water to remove dust or dirt. Next, apply a small amount of dish soap on both sides of the lenses and rub them gently with your fingers. Rinse the glasses with water again and pat dry with a microfiber cloth. Avoid using hot water, abrasive cleaners, or tissues to clean safety glasses; they can damage the lenses and reduce their effectiveness. Repeat this process regularly to ensure clear vision and long-lasting safety.
