Understanding Acuvue Oasys Contact Lenses
There are several models of Acuvue contact lenses which are manufactured by Johnson & Johnson. The Acuvue Oasys and the Acuvue Advance use a technique which embeds a silicon wetting agent. This keeps the lenses very moist which aids in getting a smooth comfortable fit. Other models offered by Acuvue are the Acuvue 2 and the 1-DAY Acuvue.
The Acuvue 2 COLOURS is used for enhancing or changing eye color and will not correct vision. All the other models discussed here will correct near or farsightedness. There are 10 different colors available with the Acuvue 2 COLOURS.
There are two replacement schedules that can be used with the Oasys lenses. You can remove them daily for cleaning and then replace them after two weeks or you can wear them continuously for as long as six nights before replacing them with a fresh pair. The Acuvue Advance need to be removed daily for cleaning for a maximum of two weeks and then are replaced with a fresh pair. The Acuvue 2 also has two replacement schedules. You can wear them continuously for up to six nights before replacing with a fresh pair or you can remove them daily for cleaning for as long as two weeks before replacing. The 1-DAY Acuvue, as its name implies, are to be worn for one day and then discarded and replaced with a fresh pair.
The Oasys family of lenses provide excellent ultraviolet light protection. The Acuvue Oasys is rated at Class I UV protection with 96% UV-A and 100% UV-B radiation. The Acuvue Advance contacts also has a Class I UV rating with 93% UV-A and 99% UV-B radiation. The Acuvue 2 and the 1-Day Acuvue have Class II UV ratings with 82% UV-A and 97% UV-B radiation.
The Acuvue brand has invested a lot of resources in making sure their lenses have a smooth and comfortable fit. They use silicone hydrogel material that allows a high degree of available oxygen to be provided to the eyes. The Oasys uses senofilcon A and allows 98% of available oxygen to pass to the eyes. The Acuvue Advance uses alyfilcon A and allows 97% of available oxygen to be provided to the eyes. Both the Acuvue 2 and the 1-DAY Acuvue are constructed of etafilcon A providing 88% of available oxygen to the eyes.
In order to keep lenses wet and smooth, the Oasys and Advance models of Acuvue lenses use the patented HYDRACLEAR technology. Oasys lenses use the next generation HYDRACLEAR PLUS and Acuvue Advance lenses use the first generation HYDRACLEAR technology. The Oasys work equally well in all types of inside or outside environments no matter how harsh. The technology enhances the smooth feeling you want where you can not feel the contact lenses and blinking is smooth.
The LACREON technology is used in the 1-DAY Acuvue MOIST. The LACREON is similar to HYDRACLEAR. It also embeds a wetting agent but it adds a wet cushion as well. This cushion mimics tears which greatly reduces friction and maintains moistness.
All Acuvue lenses have a slight blue tint to help make them visible when they are in their case. A 1-2-3 mark on each lens make them very simple to insert. Contact wearers appreciate the ease of handling.
Acuvue Oasys have special models for astigmatism and presbyopia. The Acuvue Advance also has a model for astigmatism.
