What are progressive lenses?

progressive lenses are lenses used to repair vision that offer gradation over a lens that provides several degrees of magnification. These lenses are classically prescribed by older adults who have presbyopia. Historically older adults required bifocal or even trifocal lenses for visual correction. These lenses could be unpleasant to wear, not least, because clearly different enlargement zones caused the image jumps. For progressive lenses there are no lines and no clearly delimited zones, causing much smoother vision.

progressive lenses are available in the form of glasses and contacts. In both cases, the area of ​​the lightest magnification on the top of the lens is, while the magnification increases at the bottom of the lens. The only drawback is that the lenses are somewhat distorted, which can be disturbing when viewed from the corner of the eye. Some people feel dizziness in the first few days, do not vote or disoriented when theysettled. Some optometists recommend to wear new lenses for only a few hours for a period of time, which allows patients to gradually get used to the feeling of new lenses. Progressive lenses also have to learn how to use lenses, find sweet places in different areas of lenses that provide the busiest vision for different tasks.

Fit is critical with progressive lenses. While conventional lenses may seem slightly disorienting or annoying, if they do not fit well or are bad, progressive lenses can be largely unnecessary unless well mounted. When a new couple of progressive lenses arrive, the optometrist should take time to confirm that they fit correctly, and that the wearer feels comfortable. It is also important to tap the AKE FIT before arranging the lenses and in the case of glasses to select suitable images that fit well into the face and adapt the lens of reasonable size.

these lenses are alsoKnown as graded lenses, friends, non-line bifocals or varifocal lenses. There are some alternatives to progressive lenses for people who do not wear them. One option is to use several pairs of individual lenses, with a pair of everyday glasses and a pair of glasses that can be changed as needed. Another option is to use traditional bifocal or trifocal lenses.
