1 Day Acuvue contacts are daily disposable lenses manufactured using a cutting edge hydrogel technology known as Lacreon
™. They are available in a wide range of dioptric steps for both far and nearsighted patients. The Lacreon
™ technology combines two hydrogel materials: the base hydrogel material allows superior oxygen permeability and the outer coating is comprised of a significantly more compact matrix allowing for better viscosity allowing for heightened comfort and less probability of protein buildup. Allowing the surface of the contact to absorb moisture and retain it, maintains the fluid environment necessary to maintain good corneal health. These hydrogels also permit 88% of available oxygen to reach the cornea’s surface as well as reducing friction. This design allows the patient to maintain an excellent level of acuity throughout the day as well as providing relief for allergy sufferers. In addition to these benefits, these lenses also block harmful UVA and UVB rays.
Non-compatibility and improperly fitting contacts can produce a myriad of complications resulting in discomfort, infections and compromised visual acuity. The hydrogel polymers used in 1 Day Acuvue lenses are cross-linked to provide specifications necessary to correct common refractive errors and fit comfortably. They are also designed to maintain the fluid environment of the cornea to prevent complications associated with dry eye complications. With a water content of 55%, these lenses possess a higher concentration of water when compared to other soft lenses on the market. The hydrogel polymers are hydrophilic, meaning they will absorb solutions, rewetting agents and natural tears this in turn translates to a healthy cornea, comfort and better acuity.
Oxygenation is a vital necessity for maintaining a healthy cornea. Some soft lenses may not provide as much oxygen as needed for the patient. Coupled with an extended wearing time, over the course of wear the cornea may become oxygen-starved triggering an autoimmune response. This autoimmune response results in an ingrowth of new blood vessels known as corneal neovascularization. The cornea is a transparent medium covering the visual axis of the eye allowing light to be refracted and travel the visual pathway allowing vision to occur. If this new growth of blood vessels is allowed to progress unchecked it will eventually encroach on this area of the cornea obscuring the visual pathway and compromising visual acuity. The value of utilizing hydrogels for contact lens manufacturer is their level of oxygen transmissibility therefore staving off the potential for autoimmune responses such as corneal neovascularization.
Wearing daily disposable lenses have additional benefits with respect to convenience and maintenance of visual acuities. Planned replacement lenses generally begin to lose their ability to provide their corrected acuity over a period of time. Since 1 Day Acuvue contacts are disposable, they are easily tossed out a the end of the day allowing the patient to start fresh every morning with a new pair. 1 Day Acuvue lenses are easier to maintain, are more comfortable and reduce the risk of complications.
