1.61 High-Index Computer Bifocal Lenses are a great choice for individuals who need vision correction for both near and distance tasks, particularly those who spend a lot of time in front of a computer or need a more lightweight and thinner option for their prescription. These lenses offer a high-index material, which is thinner and lighter than standard lenses, paired with a bifocal design that provides two distinct focal points: one for near vision (ideal for tasks like reading or computer use) and one for distance vision (for activities like driving or watching TV).
