Semi-finished Lenses

‘Tabula rasa’ is a Latin epithet meaning ‘blank slate’. There is a theory that people are born with a blank slate and life fills the pages. Likewise, we also produce semi-finished ‘blank slate’ lenses. We are proud to offer these high quality semi-finished blanks to you.

We know that it can be difficult to find a good supplier who can consistently deliver quality products at competitive prices, even when there is little lead time. If you are facing this problem, do not worry because we can guarantee your orders.

We can supply clear, photochromic and tinted semi-finished blanks. You can also buy them in single vision, bifocal and progressive varieties. We have six varieties in clear semi-finished blanks- Eclipse (1.50 CR-39), Campus (1.56 Mid-Index), Everest (1.59 polycarbonate), Superior (1.60 Hi-Index), Excalibur (1.67 Hi-Index) and Oceanic (1.74 Hi-Index). In Photochromic semi-finished blanks we have four varieties- Revolution (1.56 Mid-Index), Analogy (1.56 Mid-Index), Pacific (1.59 Polycarbonate) and Discovery (1.60 Hi-index). In tinted & polarized semi-finished blanks, we have three varieties- Eclipse (1.50 Sun CR-39), Aurora (1.50 Polarized CR-39) and Superior Sun (1.60 Hi-Index).
