Anti-blue Light Progressive Multifocal Reading Glasses Coated Lenses Unisex Diopter Presbyopic Ultra Light Antifatigue Eyeglasses Progressive lenses are no-line multifocal eyeglass lenses that look exactly the same as single vision lenses. In other words, progressive lenses will help you see clearly at all distances without those annoying (and age-defining) "bifocal lines" that are visible bifocals and trifocals. Example of a progressive lens design.Progressive lenses are line-free multifocals that have a seamless progression of added magnifying power for intermediate and near vision. The power of progressive lenses changes gradually from point to point on the lens surface, providing the correct lens power for seeing objects clearly at virtually any distance. Progressive lenses sometimes are called "no-line bifocals" because they don't have this visible bifocal line. But progressive lenses have a significantly more advanced multifocal design than bifocals or trifocals.  Lenses Color: Clear Gender: Unisex Lens Width: 5.2cm Lenses Material: Plastic Coating: HMC Lens Height: 4.2cm
