Serengeti FAQ
Can I get Serengeti's photochromic technology in prescription?
Yes. Serengeti's Spectral Control photochromic is surfaced into the photochromic blank, so the prescription lens reacts as fast and as far as the stock one. Same warm amber base built for driving.
Do Serengeti prescription lenses come in mineral glass?
No, the glass is factory non-prescription only. For prescription we use a high-index plastic or Trivex lens with the same tint curve; it's lighter and won't shatter, and it's the only way to surface a modern lens design.
What's the warranty on Serengeti?
Two years on the frame against defects, one year on the photochromic and polarizing performance. A slight shift in the driver tint over the years is normal; a big change inside the first year is covered.
What are Serengeti's driving lens colors and how do they affect Rx?
Drivers, the amber base, best in overcast and the most popular. 530nm, green-copper, for changing light. 440nm, blue-copper, for bright sun. All three come in prescription with polarization, and the prescription doesn't change how they look.
Are Serengeti frames compatible with progressives?
Very. The 4- to 6-base curve is modest and the pilot and cat-eye shapes give plenty of lens height for the corridor. We use a digital free-form progressive so the edges of those wide lenses stay sharp.
