The main product lines from Johnson & Johnson's contact lenses are Acuvue lenses. Today, people try to avoid using glasses for their vision disabilities, and are keener to go for contact lenses. The reasons for not using glasses vary from the habit of glasses of sliding down noses, to bending out of shape, to changing styles, to not being able to participate in physical activities without their falling off. People who have shifted to wearing contact lenses have spoken very highly of Acuvue contact lenses.

The Types of Acuvue Lenses Acuvue lenses are soft contact lenses, both for daily, as well as for extended wear. The soft hydrophilic lenses are made of water, and oxygen passes through to the eye. You can see better through them and they are very comfortable in comparison to hard contact lenses. Your peripheral vision is not distorted, as it would be by a glasses' frame.

There are four major types of Acuvue lenses:

• Normal contact lenses for people who are near sighted or far sighted - those suffering from myopia or hyperopia.
• Contact lenses for those with astigmatism. These contact lenses compensate for the irregular shape of the cornea.
• Bifocal contact lenses for older people suffering from Presbyopia
• Colored contact lenses available in a variety of colors. These are purely for cosmetic purposes for people who want to change the color of their eyes. These are available as prescription lenses for people with vision disabilities, as well as plain ones for people with 20/20 vision.

Acuvue contact lenses come with a variety of options, and are available through prescription from optometrists, and other licensed eye care specialists. You have the choice of daily disposable Acuvue contact lenses, which you need to change every day. Then there are the regular lenses that you put in every morning and remove every night. These need to be cleaned and rinsed daily and replaced every two weeks with a new pair. Acuvue lenses also have the flexible contacts that you can wear day in and day out for a week - six nights and seven days - and then replaced.

Acuvue Contact Lenses

Acuvue brands were the first disposable contact lenses available. A look at the various contact lenses from the Acuvue brand:

1-Day Acuvue - These are disposable contact lenses for myopia and hyperopia, and are discarded after a day's use.

These contact lenses come with a light blue visibility tint to help you easily locate them in the solution.

All lenses available from Acuvue, including Acuvue? Brand Toric, Acuvue? 2 ColourS' brand, Acuvue? 2 brand, Acuvue? Oasys' brand, and the Acuvue? Advance' brand, come with the quality expected from it.

The lenses from Acuvue are the most prescribed brand of contact lenses at present, and are highly popular. At present, there are two types of hydrogel - traditional and silicon hydrogel. The former ones keep the eyes moist and are comfortable to wear, but do not allow enough passage of oxygen. The latter types, allow adequate amount of oxygen to pass, but are not comfortable.

This is where the Acuvue Advanced brand has taken a leap forward with the use of Hydraclear - a new material. This moisture rich product allows more than three times the oxygen, as compared to the traditional hydrogel, to pass through to the eyes.

If you are a person who spends a lot of time in front of the computer, then Acuvue Advanced lenses are the ones for you. As most people in front of their computers blink less than they ought to, their eyes dry up faster, and your contact lenses give a scratchy feeling. The use of hydraclear in Acuvue Advanced takes care of the feeling of dryness, and you are more comfortable at your workstation.
