A curved sports eyewear frame presents particular demands in the way the corrective lens curvature is<br />
calculated. In comparison to conventional prescription spectacles, the sports eyewear lenses are angled<br />
differently in front of the eyes. While conventional prescription spectacles have virtually coincident right and<br />
left ocular planes, in frames with strongly tilted lenses the planes are appreciably angled towards each other<br />
(typically by 15° - 25°).<br />

High horizontal inclination causes optical errors: this includes the oblique astigmatism, spherical errors,<br />
prismatic errors or also errors in centring.
