Types of Bifocal Glasses in South Australia - Salisbury Optometrist in Salisbury, South Australia
People usually look up and through the distance portion of the Bifocal Glasses when focusing on points farther away. Contrarily, they look down and through the bifocal segment of the lens when focusing on reading material or nearby objects. The opticians thus place the lower bifocal portion of the lens at the same height as the wearer’s lower eyelid.
