Understanding Acuvue Oasys Contact Lenses
The Acuvue brand of contact lenses are manufactured by Johnson & Johnson. Acuvue has patented the HYDRACLEAR technology which uses an embedded silicon wetting agent to keep the lenses moist. The Acuvue Oasys employs an upgraded version of HYDRACLEAR. Acuvue Advance lenses uses the original HYDRACLEAR technology. Some other models of Acuvue lenses are the Acuvue 2 and 1-DAY Acuvue.
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.
Oasys lenses can be taken out and cleaned daily for up two weeks before replacing or you can continuously wear them for up to six nights before replacing them with a fresh pair. With the Acuvue Advance you clean them daily for two weeks and then replace them with a fresh pair of contacts. The Acuvue 2 can be worn continuously for up to six nights before replacing or you can clean them daily for two weeks before having to replace them. The 1-DAY Acuvue are worn for only 1 day and then you dispose of them and use 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.
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 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.
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.
