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.
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.
Comfort is always a prime concern for contact lens users. Acuvue lenses are made from silicone hydrogel materials. The Oasys is made from senofilcon A which allows 98% of the available oxygen to pass to your eyes. The Acuvue Advance is made of alyfilcon A which allows 97% of the available oxygen to pass to your eyes. The Acuvue 2 and the 1-Day Acuvue are made of etafilcon A and provides 88% of the available oxygen to your eyes.
Another important factors for providing comfortable wear are keeping the lens wet and smooth. The Oasys lenses use the next generation of HYDRACLEAR technology called HYDRACLEAR PLUS. HYDRACLEAR PLUS embeds a higher volume the wetting agent. This makes the Oasys lenses work well in a variety of environments, outside or inside. HYDRACLEAR PLUS increases the smoothness of the lenses. Blinking is very smooth. You can\’t feel the contact lenses at all. The Oasys Advance use the first generation of HYDRACLEAR.
There is extra moist version of the 1-DAY ACUVUE called 1-DAY ACUVUE MOIST that employs LACREON technology. LACREON like HYDRACLEAR embed a wetting agent. LACREON technology also make a wet cushion that simulate natural human tears which reduces friction and keep the lenses very moist.
All the lenses in the Acuvue family are easy to handle. They are tinted a slight blue in order to make them visible when they are in their lens case. Inserting the lenses is made easier with a 1-2-3 mark.
There are special versions of Acuvue Oasys for astigmatism and for presbyopia. The Acuvue Advance also comes in a model for astigmatism. With all the different types and feature of Acuvue contact lenses no matter what your vision needs Acuvue will work well for you.
