Spherical vision, zero distractions
Astral Sphere takes the performance DNA of Astral to the next level with a bolder, more advanced design. The new spherical lens delivers a wider, more immersive field of view while supporting both ImpactX® photochromic and Polar 3FX® polarized technologies for clarity in every light condition.
Built from lightweight, durable Rilsan® Clear, the frame combines all-day comfort with exceptional impact resistance. Compatible with our optical insert and also available in RX Direct versions with RX ImpactX® and RX RP Optics Maximus lenses, Astral Sphere is engineered to deliver sharp vision, protection and style for the most demanding activities.
Light-Adapting Performance
ImpactX® photochromic lenses are engineered to react instantly to changing light conditions, transitioning seamlessly from clear to dark. This adaptive technology ensures optimal visibility at all times, whether riding under bright sun, through shaded trails or variable weather. Made from an advanced polymer, ImpactX® lenses offer exceptional optical clarity, superior contrast and unmatched impact resistance for maximum safety. Lightweight and durable, they are ideal for athletes who demand consistent performance without compromise, delivering sharp vision and reliable protection from start to finish.

Advanced optical solutions for every athlete
Astral Sphere is engineered to deliver high-precision vision through a full range of optical configurations. The spherical lens geometry enhances peripheral coverage and visual stability, while our prescription options ensure perfect adaptability to individual needs. Athletes can choose between the lightweight optical insert or RX Direct setups featuring RX ImpactX® photochromic or RX RP Optics Maximus lenses. Each solution is designed to maintain optimal optical alignment, impact resistance and field of view—so performance stays sharp in every condition.
A Broader View of Performance
The spherical lens design enhances visual performance by expanding peripheral vision and creating a more natural, immersive field of view. Its curvature reduces optical distortion while improving depth perception and spatial awareness—key advantages in fast, technical environments. By maintaining consistent visual geometry across the entire lens surface, the spherical construction delivers stable, precise vision even at high speeds. This advanced design helps athletes react faster, stay focused and maintain control, making it the ideal choice for demanding sports where clarity and awareness are essential.

SUSTAINABLE MATERIALS
In our pursuit of sustainable frame material innovations, we're thrilled to be using Rilsan® Clear, a bio-plastic derived from 45% castor oil grown by certified farmers in Gujarat, India, who adopt improved farm waste management practices. This environmentally conscious material enables us to reduce our reliance on fossil-based materials for eyewear frames, aligning with our RideToZero committment to sustainable and responsible manufacturing.
Astral S sunglasses are made with Rilsan Clear® which allow them to be extremely lightweight yet durable along with their eco-friendly properties and perfectly suited for casual and extreme sport activities.
