Out of Standard Range Lens Upgrade This listing is for customers whose lens specification falls outside our included range. This £36 upgrade covers lenses that require individual manufacture rather than being supplied from our standard stock range. Please purchase this add-on only if we’ve advised you that it’s required, or if your lens specification is outside: * Sphere: +4.00 to -4.00 * Cylinder: Up to +/-2.00 If you’re unsure whether this applies to you, simply send us your lens details and we’ll be happy to check before you order.
