This is an age of specialization and if you have a vision problem, there's probably a CIBA contact lens that can solve it. CIBA also makes lenses for people who's vision is fine and only want to change their eye color. Or if you'd like to improve your tennis game, there's even a CIBA contact lens for you.

At one time you got contact lenses because you preferred them to glasses. Now you can get contact lenses because you prefer a new eye color. There are two kinds of color contact lenses. One kind has a light tint and is meant to add to your natural eye color. The other type of color lens has a non-transparent tint which covers your iris to change the color. There's a color CIBA contact lens for both types and they come with or without vision correction.

Another relatively recent change to contacts has been the increased popularity of frequent replacement lenses. You can get a CIBA contact lens that gets replaced daily, weekly or monthly. By using frequent replacement contacts, you avoid possible hard-to-remove deposits on the lenses, which can build up over time. And if the lens is a disposable, you only wear it once and so never have to clean it.

If you like the idea of wearing your contacts continuously for weeks at a time, there's a special CIBA contact lens that can let you do that. The Focus Night & Day lens has been approved for up to 30 days of continuous wear. By getting more oxygen to your cornea and with a surface coating that resists harmful accumulations, this lens may be worn comfortably for weeks before needing replacement.

Many contact lenses are made to correct for common vision problems like astigmatism and presbyopia. But it's also possible to get a CIBA contact lens that can improve your tennis game. This lens is made to filter certain background colors so that a yellow tennis ball stands out more clearly.
