The three types of lenses, incorporating extended-wear lenses, daily lenses and disposable lenses, are designed for the length of time they are expected to be worn. Younger people tend to favour contact lenses because they are more comfortable and convenient, while not affecting one's personal appearance. The difference is that young people actually want to look different when they wear their lenses, eschewing the transparent type of the past for the coloured variety which has invaded the market in recent years. These new products not only correct one's vision but make the eyes look more attractive and dramatic. Not surprisingly, they have drawn a large following.
Domestic brands are generally cheaper and are mainly sold in small and medium-sized cities.
Extended-wear contact lenses are more popular because they do not need daily cleaning, but some people are put off by the fact that they may cause infection. Daily lenses, which require cleaning every day, tend not to cause infection quite as easily and are gas permeable. Disposable lenses are new to the market, but a growing number of consumers are impressed by the distinctive advantages of these healthy and trendy products. All rights reserved.
