Franklin bifocals are custom made by hand in our lab in Houston, Texas. The Franklin is the ultimate custom option for divers that want the most room for near correction. The franklin is fully custimizable, so divers can choose exactly what percentage of the lens they want for near and distance correction. Professional photographers often have more than 50% of the lens corrected for near and only a small portion for distance as the majority of their time is spent looking at a monitor or camera controls within arm reach distance.
Another benefit of Franklin bifocals are for those with strong corrections. We can achieve an overall thinner lens design by using high index glass for both distance and near lenses in the mask.
Franklin orders are not available online, and divers should call for pricing.
