1 Day Acuvue Moist contacts are disposable lenses with design features that provide better comfort, easier handling and prevention of complications arising from extended wear. They are available in a wide range of powers for both farsighted and nearsighted patients. Lacreon™ technology, which deposits a wetting agent in the lens material itself, allows for maintenance of a fluid environment required for a healthy cornea as well as permitting 88% of available oxygen to reach the cornea’s surface. This reduces friction, maintains acuity, provides relief for allergy sufferers and blocks harmful UVA and UVB rays.
The eye often reacts to improperly fitted contacts or non-compatible contact lens materials. This response can give rise to complications. 1 Day Acuvue Moist Contacts are comprised of hydrogel polymers cross-linked to allow for specific curvatures, thicknesses and diameters needed to correct refractive errors of the cornea. Producing the quality and quantity of tears necessary to maintain comfortable contact wear can be problematic. At 55% water content, 1 Day Acuvue Moist Contacts contain a high water concentration when compared to other soft lenses. It is the absorption of water in the form of contact solutions, rewetting drops and naturally produced tears that allow the contact to retain moisture. These absorption and retention properties assist in prevention of dry eye complications which may eventually lead to infections or compromise of visual clarity.
Hydrogels also allow oxygen to permeate the contact from the atmosphere to the surface of the cornea. This property arrests a common problem seen in patients who have worn contacts longer than recommended. When deprived of oxygen to the cornea, the immune system begins to grow new blood vessels to provide adequate oxygenation and nutrients, this ingrowth of new vessels is known as corneal neovascularization. The cornea is a transparent medium covering the iris, pupil and anterior chamber of the eye. As light enters the eye it must pass through the cornea. In corneas with neovascularization, the blood vessels interrupt the transmittance of this light, affecting visual acuity and making it difficult for the patient to see. The inherent value of hydrogels is their biocompatibility when interacting with the eye thus staving off autoimmune responses associated with corneal foreign bodies.
Over the course of contact lens wear, conventional planned replacement contacts tend to wear and blur somewhat toward the end of their cycle. 1 Day Acuvue Moist contacts are daily disposables therefore they will maintain the same level of acuity each day since they are disposed of at day’s end. These contacts are also easier to care for since it is not required to observe a strict maintenance and cleaning regimen to prevent bacterial growth or protein deposits. Over the course of contact lens wear, this translates to an extremely low likelihood of developing infections associated with planned replacement schedules. 1 Day Acuvue Moist contacts are easier to maintain, provide better comfort than planned replacement lenses, and reduce the risk of contact lens wear complications.
