Bifocal lenses combine two different focal powers in a single lens: the upper portion for distance vision and the lower portion for near vision (typically for reading), with a visible dividing line between them. They are used to correct both near and distance vision, making them suitable for individuals with presbyopia or for teenagers requiring dual vision correction.
Advantages: One lens addresses both vision needs, offering convenience and ease of use.
