Soft contact lenses are the most popular type of contact lens. Soft contact lenses can be used to correct various vision problems, including:
- Nearsightedness (myopia)
- Farsightedness (hyperopia)
- Blurred vision (astigmatism)
- Age-related loss of close-up vision (presbyopia)
Soft contact lenses conform to the shape of your eye. They're comfortable and tend to stay in place well, so they're a good choice if you participate in sports or lead an active lifestyle. Soft contact lenses come in various types, such as:
- Daily wear. Daily wear soft contact lenses are typically the least expensive option. You wear the lenses during the day, and remove them each night to be cleaned and disinfected. How long you can use a single pair of daily wear lenses varies depending on the manufacturer.
- Extended wear. You can wear extended wear soft contact lenses while you sleep, but they must be removed for cleaning and disinfecting at least once a week. It's still important to be cautious with overnight use, though, since it increases the risk of eye infections — even if the lenses have been approved for extended wear.
- Disposable. Disposable soft contact lenses are generally the most expensive option. You wear the lenses during the day and remove them at night. They don't need to be cleaned or disinfected. You simply use them for the recommended timeframe — such as daily, weekly or monthly — and then discard them. You might consider disposable lenses if you wear contacts only occasionally, you can't tolerate disinfecting solution or you place a premium on convenience.
