LENS Need These Progressive Lenses provides clear vision at all distances (rather than at just two or three distinct viewing distances). These Lenses eliminates "image jump" caused by bifocals and trifocals. This is where objects abruptly change in clarity and apparent position when your eyes move across the visible lines in these lenses. Because there are no visible "bifocal lines" in progressive lenses, they give you a more youthful appearance than bifocals or trifocals. (This may be the reason why today more people wear progressive lenses than the bifocal and trifocals combined. Though some patients get used to the line in bifocal and trifocal lenses, many patients never adjust to it, and the visible line can cause undue eye fatigue that may even contribute to the deterioration of your vision. Progressive lenses eliminate the threat of eye fatigue for a more comfortable experience.
