Created specifically to counter the effects of presbyopia, Air Optix Aqua Multifocal contact lenses enable the wearer to see clearly at near distances, far distances, and everything in between. The lens accommodates strengths from +6.00D to -10.00D. Alcon achieves this natural gradation of vision adjustment through its innovative Precision Profile. Precision Profile Design – By combining three techniques into one design, Alcon’s engineers have minimized visual aberrations, enhanced contrasts, and smoothed transitions from near to intermediate to far objects. This comes in one lens by blending a bi-aspherical surface, an adaptive minus power profile, and a center-near design. In addition to being effective multifocals, Air Optix has a reputation of being a safe, comfortable brand. Silicone hydrogel material allows for high oxygen permeability and comfort for the eye. Smartshield helps Air Optix Aqua Multifocal contacts minimizes the drawbacks of other silicone hydrogel lenses. Smartshield Technology – A contact lens’ surface can interfere with lipids essential to eye health. Smartshield, a proprietary plasma surface design, provides an ultra-thin protective layer preventing any detrimental interaction. As an added bonus, Smartshield prevents uncomfortable deposits and buildups around the lens. Air Optix Aqua Multifocal is a monthly wear lens with an extended wear option. More cost effective than daily wear contacts, the above-mentioned technologies allow the lens to last an entire month, assuming proper care, without loss of safety or comfort. If recommended by your doctor, Air Optix Aqua Multifocal allows for up to six nights of extended wear. This means wearing your lenses through the night and only dealing with the hassle of removal once a week. The unwary consumer can pay $75 or even $90 for a box of these lenses.
