Frequently Asked Questions

What is a photochromic lens? Photochromic lenses automatically darken in UV light (sunlight) and lighten indoors or in low light. No need to swap lenses as conditions change.

Where is the bifocal reading zone positioned? The bifocal is positioned at the bottom of the lens, so your distance vision is unaffected while pedaling, and you look down slightly to read your computer or watch.

Are these good for triathlons? Yes — the Kona TT Bifocal is a popular choice for triathletes who need to read pace, power, and heart rate data on the bike and run legs.

What magnification strengths are available? +1.50, +2.00, and +2.50 in multiple frame colors.
