Sunski

Frequently Asked Questions

• What are the differences between Sunski’s TAC, CR-39, and polycarbonate lenses, and which should I choose?

  TAC lenses in Sunski frames are plant‑based cellulose laminates that are ultralight and offer good scratch resistance and polarization performance, CR‑39 provides excellent optical clarity and a classic sunglass feel, and polycarbonate is the most impact‑resistant option for active use. Choose TAC or CR‑39 for everyday clarity and lightweight comfort, and pick polycarbonate if you need maximum shatter resistance for high‑impact sports.
• Which Sunski models are best for skiing, mountaineering, hiking, or water sports?

  For backcountry and downhill skiing or mountaineering, the Tera’s classic round shape and base‑4 curve lenses provide wide coverage and comfortable all‑day wear, while the Ferrata—available with removable side sun shields—is ideal for alpine climbing or bright, windy conditions. For water sports and activities with higher impact risk, select Sunski frames offered with polycarbonate lenses and more secure temple fit.
• How does the Tera compare to the Ferrata?

  The Tera is a timeless round silhouette optimized for broad coverage and everyday alpine use, whereas the Ferrata adds removable magnetic side sun shields for peripheral light control and extra protection in high‑glare or wind‑blown environments. Both share Sunski’s lightweight recycled‑resin frames, polarized lenses (base‑4 curve), and durable stainless‑steel hardware, but choose Ferrata if you want shields for intense sun or photophobia.
• How do I pick the right lens tint and VLT for bright snow versus low‑light conditions?

  Lower VLT tints (darker lenses) are best for very bright, reflective environments like sunlit snow or midday glare—examples include mirrored options such as Indigo (around 12% VLT) or Silver CAT 4 grey (around 6.26% VLT). For overcast days, late‑season snow, or tree‑covered trails choose higher VLT tints to preserve contrast and visibility; always match tint density to expected light levels and personal comfort.
