The lenses are **scratch-resistant** and meet relevant safety standards, providing reliable **UV protection** for use in Switzerland – from the lowlands to the Alps. For the mirrored variants, the **VLT values** range from **20–23%** depending on colour (mostly **filter category 2**) and are therefore ideal for bright to changeable light. The **Photochromic** options cover **category 1–3** and vary depending on tint, for example from **43–10% VLT** (Rose Gold) or **73–14% VLT** (Graphite) – practical when light changes quickly on your ride. Grippy temples and exchangeable **nose pads** provide stability, so the glasses sit securely even at speed. ## Applications and Benefits Whether on the **road**, on **gravel routes** or **trail running**: The Nebula is designed for versatile use and fits your active lifestyle. The combination of **21 g** weight, frameless design and toric lens particularly pays off on long bike rides and in technical terrain. Thanks to the choice of **Photochromic** and **Mirror** lenses, you can adjust the **VLT** to your lighting conditions – from cloudy in the lowlands to intense sun in the mountains. The **low-bridge** nose piece improves fit for different face shapes and reduces slipping with sweat or rain. ## Fit, Care and Replacement Lenses The one-size-fits-all becomes flexible through the **exchangeable nose pads**, optimising the fit for narrow and wide noses alike. For maximum versatility, **replacement lenses** are available, including a **clear lens** with **VLT 90% (category 0)** – ideal for dusk, tunnels or very dark days. Clean the lenses with water and a soft microfibre cloth; aggressive cleaners or dry, dusty cloths can damage coatings. This keeps the optical quality intact for a long time and you can equip the Nebula with the appropriate **VLT** depending on the season. ## Variants - 8057099442893: in stock - 8057099442879: out of stock - 8057099442909: out of stock --- Source: https://kilometro.ch/en/products/glasses-109/nebula-883
