S E N N E N S L A T E (O P T I C A L)
Our Sennen optical frame is made from 100% recycled monofilament nylon fishing nets and is available with prescription lenses, offering complete sustainability, utility and optical clarity. The rectangular frame suits most medium to large face sizes.
- Italian engineered and hand-finished.
- 0% virgin plastics, 100% recycled monofilament gill nets recovered in Cornwall. These are regarded as the most dangerous form of ghost net due to their high likelihood of entanglement, as they are virtually invisible underwater.
- Matte slate grey finish that alludes to the materials origins as ocean plastic.
- Ultra-durable in-built flex hinges.
- Our frames are covered by our ‘Recycle and Replace’ lifetime guarantee – damaged frames can go back into the plastic recycling loop to create new pairs.
PRESCRIPTION LENS OPTIONS
Our prescription glasses lenses are glazed to the highest standards by a family-run manufacturing opticians in Cornwall.
We offer clear prescription lenses in three materials:
CR39 - The modern industry standard. Plastic lens with good optical clarity properties.
Mineral glass - By far the greatest optical clarity of all lens materials, with an Abbe value of 59 (vs. 32 for polycarbonate). Not recommended for strong prescriptions due to thickness. Slightly heavier than CR39.
1.67 Index - Known as 'Light and Thin' lenses, this option reduces thickness by approximately a third vs. the above options, making it ideal for stronger prescriptions. Anti-reflective coating as standard. (even thinner 1.74 Index also available on request)
Unfortunately, we are unable to produce varifocals. However, you can purchase our 'frame only' option and have them glazed with your local optician.
Please contact email@example.com for queries around lens types, options and prescription queries.
