Mano writes: The Shamir Duo lens - a bifocal worth waiting for

I really do like spectacle lenses, and would actually call myself a bit of a lens geek.

I like each new product and the innovation that goes with it, and I really enjoy widening my lens knowledge and learning about the features of a new design that the optical industry has brought to the market. Many new products are brilliant designs of varifocals or occupational lenses, many are great new single-vision products and some are ground-breaking coatings or tints.

However, there is one type of product, namely the humble bifocal, that in recent years, it seems, has been pushed further and further down the pecking order. So I really got excited when I learned that a new bifocal lens had been launched. That’s something I feared I would never see again. Yes, bifocals are still available, even though from my experience their existence is increasingly overlooked.
