Biofinity Energys is a unique monthly contact lens that features a design called 'Digital Zone Optics'. This design distributes power across the lens in a way that simulates more positive power in the center of the lens. The idea is, by having a slight variation in power at the center of the lens versus toward the edge, your eyes suffer from less strain from staring at digital devices for long periods of time. Biofinity Energys are one of the few lenses on the market to develop a solution for wearers dealing with eye strain from digital devices.
