Bifocal lenses are perfect for people suffering from presbyopia- a condition in which a person experiences blurred or distorted near vision while reading a book. To correct this problem of distant and near vision, bifocal lenses are used. They feature two distinct areas of vision correction, differentiated by a line across the lenses. The top area of the lens is used for seeing distant objects while the bottom part corrects the near-vision.
