Referred to as "no-line" bifocals or trifocals, progressive glasses are ideal for patients who have presbyopia —a vision condition marked by a decrease in the ability to focus sharply on nearby objects.
As we age naturally, our ability to see nearby objects and objects in the distance can decrease. Progressive lenses address separate visual needs in one lens—usually with a “distance viewing” field build into the upper portion of the lens, and a “near vision” field built into the lower portion.
Unlike traditional bifocals or trifocals, there are no visible lines separating the different fields of a progressive lens. Your eyes are seen clearly behind the progressive eyeglasses, you’ve got the same “look” as eyeglass wearers often half your age, and there are no “lens lines” to distract your vision.
