Which type of lenses are designed for focusing on objects 14" to 18" away from the eye?

• A. Distance lenses
• B. Near point lenses
• C. Progressive lenses
• D. Bifocal lenses

Answer: (B)

Near point lenses are specifically designed to assist individuals in focusing on objects that are within a close range, typically around 14" to 18" from the eye. These lenses help those who may struggle with seeing things at this distance, often due to presbyopia, a common age-related condition where the eye's lens becomes less flexible. By optimizing vision for this proximity, near point lenses facilitate activities such as reading, working on a computer, or engaging in crafts, enabling clear and comfortable viewing for tasks that require focus on nearby objects. Their purpose is distinct from distance lenses, which are intended for viewing faraway objects, and bifocal or progressive lenses, which serve multiple vision ranges but do not specialize solely in the close range of 14" to 18". Thus, near point lenses are essential for enhancing close-range visual clarity.
