Lined Bifocals – A Two Way Vision Correction:
The lined bi-focal glasses help oldies and adults who paced to their 40’s with solid eyesight deprivation. This pair provides continual support for reading as well as distance vision. Exhibiting a “D” segment– the lined bi-focal glasses dissect vision into two most common ranges with extra diopters to ensure clarity when zoom in on objects or be far away. The segmented lens has dual focal lengths with top one serving distance and visible “D” that empowers the reading range. The installed dual-vision lens has a standard 28mm or 35mm width that fits majority frames.
How To Measure Your Pupillary Distance:
In most cases, PD value ranges from 57 to 65 mm, with the most common one being 63 mm. At times you will find PD written as 63/61. In such cases, the first value is for Distance PD which may be entered while placing an order and the other value 61 is near PD. Repeat this process a couple of times to ensure you have an accurate measurement.
