Single Vision Lenses · CO-SV
A single-vision lens family for distance or near prescriptions, with CR-39, standard resin, polycarbonate and high-index options. Select the material, surface design and coating around the required power matrix.

Buyer fit
Suitable for distributors assembling an everyday prescription range and laboratories comparing stock versus RX routes. Start with the intended prescription and frame requirements, then select index and finish; a higher index alone does not determine finished thickness.
Start with representative samples, approve the agreed specification, then use it as the reference for trial and repeat orders.
Technical parameters
Final material, power matrix, coating, tolerances, tests, and availability are confirmed before quotation.

Planning ranges are subject to the approved power-and-diameter matrix. MR-8 is a 1.60 material; a 1.61 commercial label does not by itself identify MR-8.
Lens design
Spherical and aspheric designs describe lens geometry, while refractive index describes the material. Review them as separate choices. The qualitative illustration explains the geometry; it is not a thickness calculation for a particular prescription.
Application & selection
Send a signed sphere-and-cylinder matrix with quantities, diameter and finish. Have the receiving laboratory review frame cutout and any power combinations outside the proposed stock range before sample approval.

Procurement FAQ
A conventional single-vision lens provides one correction. A separate near segment or progressive addition belongs to a different design.
No. Specify the exact resin. Mitsui identifies MR-8 as a 1.60 material; commercial index descriptions need a substrate cross-check.
Availability is confirmed by the complete power-and-diameter matrix, coating and order quantity.
