Johnson & Johnson manufactures the Acuvue brand of contact lenses. This brand includes the Acuvue Oasys, Acuvue Advance, Acuvue 2, and 1-Day Acuvue lenses. Acuvue lenses use a patented technique called HYDRACLEAR which keeps the lenses moist and comfortable by blending in a silicon wetting agent.
With the exception of the Acuvue 2 COLOURS model, all the Acuvue lenses are used to correct near or farsightedness. The Acuvue 2 COLOURS will enhance or change your eye color and does not correct vision. Ten colors are available.
With the Oasys lenses you may choose one of two replacement schedules. First, you can take them out and clean them on a daily basis for up to two weeks before replacing them with fresh lenses. You can also continuously wear them for up to six nights until trading them for a fresh set of lenses. The Acuvue Advance are replaced after two weeks of daily cleaning. You can wear the Acuvue 2 continuously for as long as six nights before using a fresh pair or you can go for two weeks with daily cleaning before using a fresh pair of lenses. As its name indicates, the 1-DAY Acuvue are worn for only 1 day and then thrown away to be 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.
Silicone hydrogel is the main material used in making Acuvue lenses. Silicone hydrogel make your lenses feel smooth, moist and comfortable. Using senofilcon A the Oasys model allow 98% of available oxygen to be provided to the eyes. The Acuvue Advance uses a similar material called alyfilcon to allow 97% of available oxygen to be passed to your eyes. Etafilcon A is used in both The Acuvue 2 and 1-DAY Acuvue. It allows 88% of available oxygen to be passed to your eyes.
The silicone hydrogel materials used in the construction of Acuvue lenses promote a comfortable and smooth fit. Two types of lenses, the Oasys and the Acuvue Advance use a patented HYDRACLEAR technology. The Oasys actually uses a new generation of HYDRACLEAR which is called HYDRACLEAR PLUS. The PLUS version has improved the comfort level in harsh environments.
The 1-DAY Acuvue has an extra moist version named 1-DAY ACUVUE MOIST that uses LACREON technology. Similar to HYDRACLEAR, LACREON uses the embedding of a wetting agent. By adding a moist cushion, which is similar to tear drops, friction is eliminated and the lenses stay very wet.
A handy feature of the Acuvue family of lenses is the ease of handling. A slight blue tint make them visible when sitting in their case. Each lens has a 1-2-3 mark for easy insertion.
