Double segment prescription bifocals, commonly referred to as Double D bifocals within the optical industry, are specialized safety lenses designed for individuals who require enhanced visual assistance. These unique lenses feature two distinct segments resembling the capital letter ‘D’ – one positioned at the upper and another at the lower part of the lens.
Professionals such as electricians, mechanics, and plumbers often find themselves working in tight and confined spaces, necessitating the ability to view objects up close, above, and below them without the need to constantly adjust their heads. The ingenious placement of the bifocal segments on the Double D lenses allows these individuals to effortlessly glance up or down and access the full bifocal power, enhancing their efficiency and convenience at work.
Ordering Double D bifocals follows a process similar to that of standard lined bifocals. The essential information required includes the prescription details, ADD power, and pupil distance. The distance between the two segments is fixed at 14 mm. Therefore, determining the segment height merely involves measuring up to the bottom eyelid while wearing the glasses. Alternatively, adhering to the standard practice, the segment height can be set at 3 mm below the center of the lens, just like with regular bifocals.
