When you’re buying a new pair spectacles, there are a number of choices you have to make. Some of them are fun: what the frames will look like, what colour they’ll be, and so on. Some choices, however, require a little more understanding of what you’re getting yourself into. Specifically: what do you want your lenses made out of?
There are five standard lens materials: polycarbonate, CR-39 (‘normal’ plastic), mid-index plastic (1.56), high-index plastic (1.6 and upwards), and glass.
At Space Healthcare, you’ve got another unique choice – ultra-high index Tokai lenses
