Base 6 Lenses - The solution for athletes who wear prescription glasses
Sports glasses are designed to wrap around the face: great for protection and stability, but more complex when vision correction is needed. Base 6 was created to make the visual experience in sports simpler and more effective, while maintaining more natural vision.
Why Base 8 is a problem for vision
The typical wraparound shape and curved, molded lenses are two key features of sports glasses. These same features also represent the main challenges when creating and fitting corrective prescription lenses. The lens curvature of a classic sports frame is defined as Base 8.
Prescribing a Base 8 lens, besides being very expensive, can also be risky in lateral vision, because there is a real possibility of visual distortion. So you may end up spending a lot on prescription lenses for sports glasses that could cause dizziness or depth distortion when looking sideways, creating more discomfort than benefit.
In practice, the stronger the curvature, the more difficult it becomes to achieve comfortable optical performance: peripheral vision is the area most likely to reveal any sensation of distortion. For athletes, this matters a lot because the eyes are constantly shifting between terrain, trajectories, opponents, and obstacles.
Why Base 6 is the most effective choice
Base 6 lenses are the most effective solution for anyone who wants prescription sports glasses while spending a reasonable amount and minimizing the risk of lateral visual distortion.
What prescription solutions Demon offers with Base 6 lenses
Optical clip:
Optical clip: The optical clip system is a high-performance yet cost-effective Base 6 lens solution. The clip attaches inside the glasses frame. All you need are standard shatter-resistant clear lenses (anti-reflective or anti-fog treatment is optional).
The outer lens of the glasses will protect against light and UV rays, while the Base 6 prescription lenses will ensure clear vision.
In general, due to their size, prescription clips only support single-vision lenses. However, Demon has developed very large clips for some models that support both bifocal and progressive lenses.

Practical advantage: the clip works “inside” the frame, so the outer lens remains dedicated to protection and filtering, while the vision correction is handled by the Base 6 lenses.
Optical support:
Optical support: The optical support system (developed for the X-VISTA model) is a special prescription solution that “flattens” the lens from Base 8 to Base 6.
This makes it possible to maintain the wraparound shape of the sports glasses while allowing a prescription that does not create visual distortion in peripheral vision. Unlike the clip system, this technology creates a Base 6 prescription sun lens.
Aesthetically, there is no visible prescription clip, which some athletes may not like, while still offering the technical performance of a true sports frame, but with Base 6 prescription lenses.

Key strengths: you keep the sporty geometry and clean aesthetics, with a solution designed to make vision correction more comfortable.
- Prescription sports frames:
- Prescription sports frames: The prescription sports frames in the Demon collection, such as SPECIAL and LAYER, are Base 6.
They are made with the same materials as classic sports glasses and feature the aggressive design typical of sports eyewear. They are created with minimal curvature to wrap the face effectively and provide protection against air and flying debris, while also helping to reduce fogging.
As with the optical support described above, these frames can be fitted with either clear prescription lenses or prescription sun lenses, for example photochromic lenses, so the glasses can be used both indoors and outdoors.
