Which type of lens is specifically designed to assist with reading up close?

The selection of bifocal lenses as the answer is appropriate because these lenses are specifically constructed to provide vision correction for two distinct viewing distances—one for distance vision and the other for near vision. The lower portion of a bifocal lens is typically designed with a prescription tailored for reading or close-up tasks, allowing individuals with presbyopia to read comfortably without needing to switch glasses.

Progressive lenses, while also helpful for vision at multiple distances, offer a gradual transition between different focal zones and are not strictly limited to just reading; they cater to both near and distance vision more seamlessly. Distance lenses, on the other hand, are solely for correcting distance vision, leaving those with near vision problems such as presbyopia at a disadvantage. Lastly, toric lenses are specifically designed to correct astigmatism and are not focused on addressing near vision needs. Therefore, bifocal lenses are the best fit for the purpose of assisting with reading up close.
