RAEN optics Training

Frequently Asked Questions

• What materials and lens technologies are used in RAEN Training sunglasses?

  RAEN Training sunglasses use handcrafted acetate frames (with some stainless steel options) that are cut, polished, and hand-finished for durability and comfort, plus wire-core temples for on-face adjustment. Lenses are premium Carl Zeiss Vision optics, often available in polarized options for enhanced contrast and UV protection suited to active use.
• How do I choose the right RAEN frame size for training and active use?

  Match frame measurements to your face: narrow frames typically have 46–49mm lenses (good for small faces), medium frames are 50mm+, nose bridges usually range 18–23mm, and common temple lengths are 143–150mm; Remmy’s 49mm is a popular small/medium example. Focus on keeping the eye centered in the lens and ensuring the frame sits comfortably on cheekbones without sliding during movement.
• Which RAEN models are best for high-glare conditions like snow, water, or road training?

  Choose models fitted with Carl Zeiss polarized lenses—Alvez (ultralight, rugged), Wiley, and Rifka aviator-style frames are well-suited for glare-prone activities thanks to polarization and high-clarity optics. For very bright conditions pick darker lens categories (category 3 for sunny days, category 4 for ultra-sunny water or snow environments) but avoid category 4 lenses where traffic visibility is required.
• Can RAEN Training sunglasses accommodate prescription lenses?

  Many RAEN models can be fitted with prescription lenses; Carl Zeiss Vision prescription options are commonly used for maintaining optical clarity and polarization. Check the specific model’s frame compatibility with an optician, since lens replacement and polarization in prescription form depend on the frame and lab capabilities.
• How does the Remmy compare to the Alvez for training and active sports?

  The Remmy is a bestselling round, unisex frame (small-to-medium) with a classic silhouette that works well for everyday active use, while the Alvez is designed to be ultralight and rugged with a fit optimized for high-movement activities. Both can be ordered with Carl Zeiss polarized lenses, but choose the Alvez if you want a more secure, sport-oriented fit and the Remmy if you prefer a timeless round aesthetic with versatile wearability.
