ML Prisma

ML Prisma is the name for a system of frames, flip-ups and lenses which could be combined into an endless of different ways. ML Prisma is available in two different sizes. 48 mm for adults and 38 for children.

The purpose of ML Prisma  is:

- to improve the optical quality towards lenses as the “Fresnel Press-on”
- to in longer perspective lower the costs because it is re-usable.

Frame and flip-up
