The many rival companies out there are no better. We're currently living in an era of rich marketing. When choosing a complex product such as contacts, requires you to be highly educated in order to make any sense of what you're buying. With that said, you'd want to look at all the rival companies and see how their products fare with the Ciba vision lens.
One of the first options that you'll have available to you is the coopervision contact lenses. Thanks primarily to the material used to create them (called Aqua form); they are very wearable and comfortable for the eyes. These contacts are designed to be softer and wetter than all its competitors, with longevity of wear being the primary focus of this product.
Acuvue have a similar ethos with their current line of contacts. Their advanced line is designed specifically for people who suffer from astigmatism. Up until only recently, people who suffered from astigmatism were unable to wear contacts, but with the new advances in technology, these people can now do away with their ugly glasses.
The reason why this has all been made possible is because of the new material used to make the contacts called silicone hydrogel. This material is designed to ensure more moisture and oxygen passes through the eyes. Expected levels for these contacts are around 95 percent, which is as close to natural levels as you'd get, anywhere else. The result of this means that people will be able to wear the contacts continuously for several days.
The number of different lenses by Ciba that you can find in this area is fairly large. You will find detailed product information outlining the levels of water, oxygen and comfort. It may all seem rather overwhelming, but the reality is that it's all designed to ensure comfort when you finally put those contacts on.
In theory, everything always seems to sound nice, but we've all fallen victim to marketing hype at least once in our lives. The only way to truly determine the value of a product is through experience, but because this product in particular costs around 30 per pack, it can seem rather steep parting with that much money for something that may or may not even work.
The best thing for you to do is to seek the advice of a professional. An optician should be able to tell you which product is best for you. The information that you get from them should be enough to determine which of the various products offers the most value for your money. So, when you're looking at the material used to create the coopervision contact lenses, or any lens for that matter, you'll be in a much better position to make a decision that is well informed.
