Overhead work can be a pain in the neck!
Why suffer needlessly with overhead work? The Double D Trifocal.is a clever solution.
Double D Trifocals are designed specifically for Electricians, Plumbers, Mechanics and any other tradesmen who are over the age of 40 and engaged in constant overhead work. These lenses allow you to see clearly overhead at arms length distances and yet also allow clear distance or reading vision.
- The unique upper near segment allows you to see overhead work clearly with a choice of near or intermediate viewing distances
- The lower near segment allows for normal reading and close work when looking down
- The middle "Distance" zone is ground with your distance prescription
- Available in plastic material
- Available in two widths - 28mm (regular) and 35mm (extra wide)
